How to Use This Document

This is the complete printed companion to The Ashrun Affair — a solo Cognitive Game (COG) adventure played entirely in the imagination. Everything in the digital version is reproduced here, including all branching paths, every NPC conversation, all fourteen clues, and all four endings.

You can use this document in three ways:

•         Read-Through: Experience the full adventure from start to finish as a narrative.

•         Reference Guide: Use it as a GM's companion if running this for a group.

•         Study Tool: Analyze the wicked problem structure and critical thinking moments — marked throughout in shaded boxes.

 

What Is a Wicked Problem? A wicked problem is a challenge whose causes are intertwined with the systems that produced them. Every proposed solution creates new problems. There is no neutral action. The people responsible for the problem are often also the people needed to fix it. The Ashrun Affair is designed as a wicked problem: you will uncover multiple overlapping causes, competing stakeholder interests, and no ending that satisfies every value simultaneously.

 

Part One: Setting the Stage

The City of Thornhaven

Thornhaven sits at the throat of the Ashfall Valley like a stone lodged in a wound. Three thousand souls. One river. Four factions. And for the last six weeks — the water has been killing people.

Not quickly. That's the cruel part.

A child drinks from the Ashrun River on a Tuesday. By Friday she has the shakes. By the following Thursday, her father is carrying a small pine box to the hill cemetery outside the eastern gate.

Fourteen dead. Forty-seven sick. And the city is fracturing.

 

The Four Factions

The Merchant Council says it's sabotage — someone upstream is poisoning trade to break their monopoly. They want the river locked down and the upstream villages investigated.

The River Cult of Sorrow's Mouth says the river itself is expressing divine judgment. They claim the Ashrun is alive and punishing Thornhaven for building the Intake Aqueduct that 'stole its path.' They want the aqueduct torn down.

The Warden's Watch says it's a magical plague, something uncorked from the old ruins of Fort Ashfall two miles upstream. They want the ruins sealed and anyone who entered them in the last three months arrested.

The Refugees — two hundred people who fled a flooding valley three months ago — are being blamed by everyone. They camped upstream for six weeks before being allowed inside the walls. Nobody says it out loud, but everyone thinks it.

 

The Inciting Letter

From Mira Soldane, Apothecary of Thornhaven: "I don't know who to believe. I don't know what's true. I know fourteen people are dead and nobody is asking the right questions. Come. Please. I need someone with fresh eyes and no loyalties. — M."

Part Three: Persons of Interest

There are five key NPCs in Thornhaven. Each knows a different piece of the truth. Each has reasons to share some things and conceal others. The player interviews them in any order.

Mira Soldane

Apothecary of Thornhaven

Mid-40s. Sharp eyes behind round spectacles. Her hands are stained with tincture-work. She hasn't slept properly in a month.

 

Opening Scene

She's waiting at the door of her shop before you've knocked. The inside smells like camphor and worry.

"You came," she says, and the relief in her voice is so raw it almost hurts. "Sit down. I need to tell you everything, but I need you to listen before you form opinions. Can you do that?"

 

Clues This NPC Can Reveal

•         The Symptoms

•         The Timeline

•         The Aqueduct's Hidden Design

 

Bram Corsley

Captain, Warden's Watch

50s. Military bearing going soft around the edges. Looks like a man who's been right his whole life and is terrified he might finally be wrong.

 

Opening Scene

The Watch barracks smells like leather and anxiety. Captain Corsley receives you in his office, standing.

"I know why you're here. Soldane's been talking to everyone." He crosses his arms. "I'll tell you what I know — but understand that I have six councilors breathing down my neck and two hundred refugees I can't account for and ruins that nobody should have been in. I'm not the villain here. I'm the man trying to hold a dam together with his hands."

 

Clues This NPC Can Reveal

•         Fort Ashfall: What's in the Records

•         The Interrogation Records

•         Warden Aldric Moss: Reconstructing His Last Days

 

Sable Dorn

Voice of the River Cult

Late 20s. Intense. Wears river-blue robes that have seen hard use. Believes every word they say — which makes them both more trustworthy and more dangerous.

 

Opening Scene

You find Sable at the river's edge at the south gate, standing in ankle-deep water, watching the current.

"I knew someone would come." They don't turn around. "The river tells you things, if you're quiet. Most people stopped being quiet a long time ago."

They finally face you. Their eyes are the color of slate.

"Ask your questions. I'll answer the ones that matter."

 

Clues This NPC Can Reveal

•         What the Cult Found at the River

•         The Original Aqueduct Plans

 

Oskar Venn

Refugee Elder

60s. Weathered. Dignified in the way of someone who has survived things that should have broken them. Deeply tired of being suspected.

 

Opening Scene

The refugees are housed in the old granary near the west gate. Oskar meets you in the courtyard, where children are playing a quiet game with stones.

"You want to know if we poisoned the river." He says it flatly, without accusation. "Everyone does. Nobody asked us what we saw upstream."

He looks at the children. Then back at you.

"I'll tell you. Because fourteen people died, and whoever did this is still out there, and my people are going to be blamed for it if you don't find the truth."

 

Clues This NPC Can Reveal

•         What the Refugees Found Upstream

•         The Barrel

 

Councilor Yeva Prace

Head of the Merchant Council

55s. Expensive clothes, inexpensive ethics. She's smart, which makes her more dangerous. She wants a solution — specifically, one that doesn't implicate her.

 

Opening Scene

The Council chambers are the most comfortable room in Thornhaven. Prace receives you like a business transaction.

"I'll be direct." She folds her hands. "I want this solved. Fourteen dead people are terrible for commerce, for morale, and for my reelection. I'm prepared to fund a thorough investigation."

She pauses.

"Within reason."

•         The Upstream Contracts

•         What the Council Owes

 

Part Four: The Evidence

There are fourteen distinct clues the player can discover. Each is presented here in full, including the dialogue that delivers it and the Critical Thinking Note embedded within.

1. The Symptoms

Source: Mira Soldane

"The sickness isn't consistent — and that's what keeps me up at night," Mira says, spreading a hand-drawn chart across her worktable. "Look. The first cases — weeks four through six — were upstream residents. The Millbridge neighborhood, close to the Intake Aqueduct. Then it spread downstream. But here's the thing no one is talking about: the symptoms aren't the same."

She points to two columns. "Early cases: joint pain, disorientation, a distinctive blue tint to the nail beds. Classic heavy-metal poisoning. Probably arsenic or lead from an industrial source — old pipes, perhaps, or a runoff site."

She moves her finger. "Later cases: fever, internal bleeding, those strange ulcerations on the mouth. That's not metal poisoning. That's biological. Possibly a waterborne pathogen — something bacterial or fungal."

She looks at you over her spectacles.

"Two different things are happening in this river. Possibly at two different times. Possibly from two different sources. And they arrived close enough together that everyone is treating it as one problem."

 

CRITICAL THINKING NOTE This is evidence of a compound problem — two separate causes that overlap in time, creating the appearance of a single cause. What assumptions might investigators be making by treating this as one event? Consider: what would a single-cause theory look like, and what evidence would contradict it?

 

2. The Timeline

Source: Mira Soldane

Mira produces a careful log, dated and annotated. She's interviewed every family she could reach.

"The refugees arrived at the upstream camp eleven weeks ago. They were there for six weeks before the Council allowed them inside the walls. During that time, no illness. None. I checked with their elder — Oskar Venn. Not a single case of this specific sickness."

"The first Thornhaven illness appeared four weeks ago. That's five weeks after the refugees arrived upstream."

"Now. If the refugees had been fouling the water from day one, we'd have had illness from week one. We didn't. So either they started contaminating the water exactly five weeks ago — for some unknown reason — or..."

She trails off, letting you finish the thought.

"Or something else happened five weeks ago upstream."

She taps the map near the marked ruins of Fort Ashfall.

"I asked around. Five weeks ago, a group from the city went to the ruins. To scavenge, perhaps. Or to investigate. I can't prove a connection. But the timing bothers me enormously."

 

CRITICAL THINKING NOTE Post hoc ergo propter hoc — 'after this, therefore because of this' — is a logical fallacy. Correlation isn't causation. But timeline is still evidence worth examining. What would you need to prove the ruins are responsible versus merely coincidental? List three alternative explanations for why illness started five weeks ago.

 

3. The Interrogation Records

Source: Captain Corsley

Corsley slides a folder across his desk with visible reluctance.

"I questioned seventeen refugees. Voluntarily — mostly. They all say the same thing: they didn't touch the river upstream except to drink from it and wash in it. Their camp was north of the ruins, not near the industrial channels."

He pauses. "I believe them. I hate that I believe them, because it would be simpler if I didn't."

"But here's what I found odd." He leans forward. "Three of them — all three adults, none of the children — show no signs of illness despite drinking the same water as the sick. Why are those three adults immune? I sent samples to a mage in the next city. She wrote back that the adults in question show traces of prior exposure to something she called 'Ashfall mineral compound' — an old term. Said it was documented in texts about Fort Ashfall."

He lets that hang in the air.

"Which means those three had been in the ruins. Or near enough to absorb something from them. Before the camp. And they've been telling me they'd never been there."

 

CRITICAL THINKING NOTE Inconsistent testimony isn't proof of guilt — people lie for many reasons, including fear of being blamed. What are three reasons the refugees might lie about the ruins that have nothing to do with poisoning the water? How does the prior exposure evidence change (or not change) the conclusion?

 

4. Fort Ashfall: What's in the Records

Source: Captain Corsley

"Fort Ashfall was abandoned two hundred years ago," Corsley says, pulling a survey report. "Built during the Copper Wars to control the river route. Decommissioned when the wars ended. But before it was abandoned, they used it as a storage site for weapons-grade alchemical compounds — precursors to the fire-oil they used in the siege engines."

He looks uncomfortable. "Those compounds were sealed in stone vaults. The survey from forty years ago said the seals were intact. I sent a man to check them five weeks ago."

He goes quiet.

"He didn't come back."

A long silence.

"His name was Warden Aldric Moss. Twenty-two years old. I haven't reported it up the chain because the moment I do, the Council seizes control of the investigation and I lose whatever chance I have of actually solving this."

He meets your eyes. "Find out what happened to Aldric. If the vaults were breached — whether by accident, by the refugees, or by someone else — that's your industrial contamination source. The early cases."

 

CRITICAL THINKING NOTE Corsley is withholding information from his superiors to preserve his investigation. Is this ethical? What are the competing goods here — transparency vs. effectiveness? What could go wrong if he continues to conceal it? What could go wrong if he reports it? Is there a middle path?

 

5. What the Cult Found at the River

Source: Sable Dorn

Sable leads you along the river's edge to a place where the bank curves and the water runs slower. They crouch and point to a series of marks on the riverbed stones — visible through the slow current.

"These weren't here two months ago. I walk this bank every third day. These marks are carved, not natural. And see the color of the stone around them? That orange-brown stain — that's a biological residue. Fungal, I think, though I'm no scholar."

They stand. "Someone carved a ritual circle into the riverbed. Not ours — the River Cult doesn't do submerged carving, that's not our practice. This is older. Pre-Thornhaven. Fort-era."

They look upstream. "There's a similar set of marks near the Intake Aqueduct intake point. I showed them to Councilor Prace three weeks ago. She told me to stop looking at the river and go home."

They face you. "I don't know if the carvings caused the illness. I don't think carvings cause illness by themselves. But I think someone activated something old. The carvings are a symptom of a different problem — something the Fort people left behind that wasn't just in the vaults."

 

CRITICAL THINKING NOTE Sable's evidence is physical but their interpretation is speculative. How do you evaluate evidence from a source who has a strong ideological framework (the river is sacred and alive) that shapes everything they observe? Does their belief system make their physical observations less reliable? More reliable? How do you separate the observation from the interpretation?

 

6. The Aqueduct's Hidden Design

Source: Mira Soldane

"I asked an old engineer who helped build the Intake Aqueduct twelve years ago," Mira says. "He was reluctant to talk, but eventually he told me something."

She unfolds a technical diagram — old, hand-drawn, covered in annotations.

"The Aqueduct was built on the site of an older drainage channel. A Fort-era channel, used to drain overflow from the storage vaults so it wouldn't contaminate the main river. The original plans called for the new aqueduct to route around the old drainage points. But that would have cost more — required digging through granite."

Her voice tightens. "So they routed through the old drain points. Sealed them with mortar and a prayer and hoped the compound residue in those old channels was too old to matter."

She looks at you directly. "It wasn't. And two hundred years of geological pressure, and the recent tremors — there were small earthquakes three months ago, did anyone tell you that? — may have cracked the seals. Not completely. Enough."

"The early-case metal poisoning? I think it's leaching from cracked Fort-era drainage lines into the aqueduct channel. Slow, chronic, invisible until it isn't."

"And the biological cases? Those are something else. Something newer."

 

CRITICAL THINKING NOTE The aqueduct decision was made by individuals who weighed short-term cost against long-term risk — and chose wrong. This is a classic systems-level failure. Who bears responsibility: the engineers who cut corners, the councilors who approved the budget, or the society that normalized cost-cutting in infrastructure? Is there a meaningful difference between negligence and corruption in this context?

 

7. What the Refugees Found Upstream

Source: Oskar Venn

Oskar speaks slowly and without self-pity.

"Three of our people went to the ruins. I know. I told Bram they didn't. I lied, and I'm not proud of it, but I knew what would happen if I admitted it."

He folds his hands. "They went exploring — we'd heard stories that Fort Ashfall had old goods worth salvaging. They found the outer courtyard, nothing remarkable. Then they found a vault that had been recently opened. Not by us — the hinges were oiled and the lock was cut, not broken. Someone else had been there first."

"Inside were rows of old sealed containers. Most were intact. Two had been opened, their contents removed. And on the floor, there was a body."

A long pause.

"Young man, in Warden's uniform. He'd been there for some days. He hadn't been killed — no wounds. He'd collapsed. We didn't know what to do. We didn't touch anything. We sealed the vault behind us and we left."

He looks at you steadily. "We should have reported it. I know that. But we were refugees. A dead Warden in a vault we'd entered illegally? We would have been hanged before you could say 'investigation.'"

 

CRITICAL THINKING NOTE Oskar's group made a morally complicated choice — withhold evidence to survive, at potential cost to others. Evaluate this choice: Was it rational? Was it ethical? Are those two questions the same thing? What would you have done? Does the power imbalance between refugees and city authorities change the ethical weight of their silence?

 

8. Warden Aldric Moss: Reconstructing His Last Days

Source: Captain Corsley

Corsley gives you Aldric's patrol log — what there is of it.

"He signed out five weeks ago, destination listed as 'upstream survey.' That was his assignment — check the vault seals. He had a partner scheduled but the partner fell sick the morning they were to leave. Food poisoning, we thought at the time."

He points to a separate document. "I found this in Aldric's room afterward. He wasn't supposed to go alone. His instructions were to wait for a replacement partner. He didn't wait."

The log's final entry reads: "Vault 3 seal cracked at the base — visible seepage at the drainage point. Containers 7 and 8 appear missing. Recent footprints in the dust, more than one person. Going inside to assess."

That's the last entry.

"He found the same thing the refugees found. But earlier. And he went in." Corsley's voice is flat. "The vault residue — whatever leaked when containers 7 and 8 were removed — it's what killed him. Or incapacitated him severely enough that he died of exposure."

He pauses. "Someone removed two containers of Fort-era alchemical compound. Someone who knew what they were taking. Someone who went there before Aldric, before the refugees. Five weeks ago or more."

 

CRITICAL THINKING NOTE Aldric disobeyed protocol and died for it. But his disobedience also produced critical evidence. How do you evaluate a rule-breaking action whose outcome was both fatal and valuable? Does outcome determine the ethics of a decision? What does this imply about rules and protocols — are they always worth following?

 

9. The Barrel

Source: Oskar Venn

"There's something else," Oskar says quietly. "I didn't mention this to the Captain because I didn't think it was significant. I'm reconsidering."

He leads you to a corner of the granary where a group of adults sit at tables. He speaks to one of them briefly, and the man goes to a locked chest and returns with a small sealed clay jar.

"When we were still at the upstream camp — week three — one of our younger men found this floating in the river, snagged on a root. He fished it out. We thought it was preserved food."

The jar has a wax seal. Stamped into the wax: a merchant's mark. Mira's earlier diagram surfaces in your memory — the same mark appeared on the Merchant Council's upstream contracts.

"We didn't open it. It smelled wrong through the seal. Like copper and something biological, something alive."

He looks at you.

"Someone dropped this into the river. Above our camp. Above the intake aqueduct. Someone who had access to something from those vaults and something biological. And they wanted it to reach the city."

 

CRITICAL THINKING NOTE The barrel suggests deliberate action — this isn't purely accidental infrastructure failure. But two different types of contamination, one accidental and one deliberate, occurring nearly simultaneously strains credibility. What alternative explanations exist for the barrel? What evidence would definitively distinguish deliberate poisoning from coincidence? How does the merchant's mark change your probability assessment?

 

10. Who Benefits From Thornhaven's Crisis

Source: Councilor Prace

Prace chooses her words like she's spending coin.

"You want to know about competition. Fine." She folds her hands. "The Ashfall River trade route is worth forty thousand gold marks a year. Thornhaven controls the bottleneck. Three other cities would benefit significantly if Thornhaven's reputation for safe water was destroyed — if merchants rerouted through the highland passes."

She names them: Velmoor, Carrick's Landing, and Ostwend.

"I have contracts with all three." She says it without flinching. "Standard trade agreements. I'm not in the business of poisoning my own customers."

Then, after a pause: "But I'm aware that certain former partners of mine — investors who were bought out when I restructured the Council's trade arrangements two years ago — might feel differently. Men and women who lost significant money and blame me personally."

She says a name quietly. You don't recognize it, but the name is written in the margins of Aldric's log. Someone he'd spoken to.

"I'm not telling you this because I trust you," she adds. "I'm telling you because if this goes wrong and it comes out that I sat on information, it ends me. I'd rather be inconvenienced than destroyed."

 

CRITICAL THINKING NOTE Prace has a strong incentive to point blame away from herself. Does that make her information less reliable? How do you evaluate testimony from a source with an obvious self-interest in a particular narrative? What corroborating evidence would you need to trust what she's told you? Note that the name she gives appears in Aldric's log — what does that independent corroboration suggest?

 

11. The Upstream Contracts

Source: Councilor Prace

The contracts are dense with legal language, but you find the relevant section.

The Merchant Council holds extraction rights to a mineral seam three miles upstream — a seam that runs directly beneath Fort Ashfall. The extraction operation was licensed eight years ago, quietly, with minimal environmental review. The operation was paused two years ago due to "structural concerns" — a note in the margin, barely legible, reads: "drainage integrity compromised, recommend immediate survey of Fort-era channels."

The survey was never conducted.

Instead, the extraction license was quietly sold — to a holding company that Mira's engineer contact, when pressed, connects to the name Councilor Prace mentioned: a former investor with a grudge.

The extraction operation resumed fourteen weeks ago. Two weeks before the refugees arrived upstream.

And extraction operations, poorly managed, in an area with Fort-era drainage channels that connect to the Intake Aqueduct intake...

 

CRITICAL THINKING NOTE You now have multiple overlapping causes: cracked infrastructure, a resumed extraction operation that destabilized it, a deliberate act with the barrel, and a political cover-up. A wicked problem isn't just complicated — it means the causes are intertwined, the stakeholders are also implicated, and solving one part may make another part worse. Draw a diagram: who contributed to this crisis, and how do their actions connect?

 

12. What the Council Owes

Source: Councilor Prace

You press Prace on the extraction contract sale. Her composure doesn't crack, but something behind her eyes tightens.

"The Council had debts," she says finally. "Three years ago, the winter was bad. We borrowed against future trade revenues. When the revenues underperformed, the debt called early. We had to liquidate assets."

"The mineral rights were an asset."

"The man who bought them — yes, I know who it is, don't look at me like that — he knew what he was getting. He also knew about the Fort-era drainage concerns. He bought the rights because of them. Because he understood that if the extraction restarted improperly and contamination resulted, the liability would trace to the Council, not to him. The contract indemnified him."

She presses her lips together. "I didn't know, at the time, that he intended to use the contamination deliberately. I thought he was buying a chance to sue us. I didn't think he would—"

She stops.

You wait.

"There's a name," she says. "He has a warehouse near the north gate. I have no proof. But the timing, the barrel you described — if someone removed Fort-era compounds and introduced them deliberately..."

She looks out the window at the river.

"Find him before he finds a way to blame the refugees. Because he will. And the Council will let him, because it's convenient."

 

CRITICAL THINKING NOTE Prace helped create this situation through financial decisions, then failed to act when she suspected deliberate harm. She is now trying to direct you toward the 'real villain.' How complicit is she? How do you decide how to allocate blame across a chain of decisions where each person thought someone else would prevent the worst outcome? Does intent matter when outcomes are severe?

 

13. The Original Aqueduct Plans

Source: Sable Dorn

"The River Cult keeps records," Sable says, with something like quiet pride. "Everyone forgets us when they want to remember things. They come back when they can't find what they need anywhere else."

They produce a rolled sheaf of documents from a waterproof case. These are the original plans for the Intake Aqueduct — predating the construction by two years, showing the initial design.

The alternative routing — the one through granite — is marked in red, with a note in careful script: "Costly but necessary — old Fort drainage channels in current route show evidence of alchemical residue. Recommend complete avoidance."

Beside this note, a different hand has written: "Council approved alternate route B — cost differential unacceptable. Risk assessed as negligible."

The signature beside the approval is Councilor Yeva Prace. Twelve years ago, before she was head of the Council. Her first major vote.

Sable watches you read it. "I'm not trying to destroy her," they say. "I'm trying to save the river. Those are different things. But sometimes the same information does both."

 

CRITICAL THINKING NOTE This document changes Prace's culpability significantly — she didn't just inherit a bad situation, she helped create it. But she was also younger, under budget pressure, and told the risk was negligible. How does context affect moral responsibility? Does intent matter when outcomes are severe? At what point does negligence become something worse?

 

14. The Deliberate Hand: Ferren Vask

Source: Synthesis

The name Councilor Prace gave you is Ferren Vask.

You find him through the warehouse, as she said — but not before you've pieced together what he did.

Vask was a mining investor, bought out from the Council's mineral operation two years ago. He spent those two years learning everything he could about Fort Ashfall's drainage architecture — the same records Mira's engineer had seen, the same survey reports that said not to route the aqueduct through the old channels.

He resumed extraction fourteen weeks ago. Not to profit from minerals — but to stress the old drainage points. To accelerate what was already slowly happening.

Then, when the passive leaching wasn't killing people fast enough — when it was just making them slightly ill, a mystery, not a crisis — he obtained a sample of the residue from the Fort vaults. He paid two refugees, separately, to enter the ruins — told them there were valuables there. They weren't his agents, just poor people doing what he asked for coin. They left. They found Aldric. They ran.

Vask retrieved the containers himself. Mixed the compound with a cultivated biological agent — a fungal toxin that amplifies the effects of the metal contamination — and deployed it. The barrel.

He wanted a crisis. Not mass death — just enough to collapse Thornhaven's reputation, trigger an emergency Council vote to liquidate the trade route rights, and buy them at catastrophic discount.

Fourteen people died.

He is, when you find him, in his warehouse counting crates, apparently unconcerned. He's been watching the investigation fumble for weeks.

He looks at you and doesn't reach for a weapon.

"You can prove very little," he says.

He's right. And wrong. And therein lies the hardest question of this entire investigation.

 

CRITICAL THINKING NOTE The full picture is now assembled. But notice what you're holding: a corrupt financial decision that enabled infrastructure failure; an engineer who flagged the danger and was ignored; a man who caused deliberate harm but is legally insulated; refugees who withheld evidence out of survival fear; a Warden Captain who covered up a death; a Cult with partial-but-real evidence that was dismissed; and 47 still-sick people who need the contamination source eliminated NOW. This is the anatomy of a wicked problem. Before reading the endings, write your answer: what would you do?

 

Part Five: The Wicked Problem — Analysis

Before the player chooses a resolution, they are invited to stop and analyze what they've found. The digital version presents this as a formal reflection screen. In print, use this section as a guided analytical framework.

 

The Anatomy of the Problem

The Infrastructure Failure

The Intake Aqueduct was built through old Fort-era drainage channels despite an engineer's explicit warning. This was approved by a young Councilor Prace under budget pressure twelve years ago. The decision has been leaching metal contamination into Thornhaven's water for years. Recent earthquakes accelerated what was already happening.

 

The Deliberate Act

Ferren Vask, a displaced investor with a grievance, used the existing contamination as cover. He restarted extraction operations to stress the drainage points further. He retrieved alchemical compounds from Fort Ashfall — indirectly causing Warden Aldric Moss's death. He introduced a biological amplifier into the river via a sealed barrel. His goal: collapse Thornhaven's water reputation and buy the trade route rights at catastrophic discount.

 

The Cover-Up Chain

Captain Corsley concealed Aldric's death to protect his investigation. The refugees concealed their visit to the ruins to protect themselves from being scapegoated. Councilor Prace concealed the aqueduct approval document because it implicates her. Each concealment made the problem harder to solve and cost time — and lives.

 

The Scapegoat Mechanism

With a crisis and no clear explanation, everyone defaulted to blaming the refugees — the people with least power and most visibility. This is a pattern as old as crisis itself. The refugees are innocent of the main crime but implicated in minor ways that make them convenient targets.

 

The Compound Cause

Two different contamination sources — industrial leaching and deliberate biological introduction — overlapped in time, creating what appeared to be a single problem. This confused every investigation and allowed the deliberate actor to hide behind the accidental one.

 

 

Five Critical Questions

These questions have no correct answers, but they shape what action is appropriate:

 

Who is most responsible?

Vask caused deliberate harm. Prace made a negligent decision twelve years ago. Corsley committed an ongoing cover-up. The system rewarded cost-cutting over safety. Rank these — but notice how difficult that ranking is.

 

What does 'solving this' actually mean?

Justice for the dead? Prevention of future harm? Political stability? Medical recovery for the sick? These goals are not always compatible. Which do you prioritize?

 

What do you owe to the refugees?

They are innocent of the main crime. They also withheld evidence. They are the most vulnerable party. Does that vulnerability change your obligations to them — or to others?

 

What can you actually prove?

Evidence and truth are not the same thing. You know things you cannot demonstrate. What happens to justice when the full truth is unprovable?

 

What systems created this?

Vask is an individual villain — but he operated inside a system that made his plan possible. If you only stop Vask, have you solved anything?

 

Part Six: The Four Endings

The player now chooses how to act. There is no correct ending. Each represents a legitimate value or set of trade-offs. All four are presented here in full, followed by the final debrief.

Choice A: Expose Everything

Bring all evidence into public light, regardless of the fallout.

 

You compile every piece of evidence and present it publicly — Vask's deliberate act, the Council's infrastructure negligence, the covered-up Warden death, the refugees' silence, all of it.

The result is chaos, then catharsis.

Vask is arrested on circumstantial evidence and held pending investigation. He'll likely spend years in court. Maybe he'll be convicted. Maybe not.

The Council is forced to authorize emergency funds to seal the Fort drainage points and reroute the aqueduct's intake. The repairs take three months. During that time, fourteen more people get sick.

The refugees are exonerated — but the community that blamed them doesn't apologize. They leave anyway.

Captain Corsley is censured for concealing Aldric's death. He resigns. He'll spend the rest of his life wondering if he should have reported it.

Mira Soldane saves thirty-one of the forty-seven sick. Sixteen die before the contamination is fully stopped.

The city rebuilds. Slowly. Imperfectly.

 

What You Gained The full truth is on record. The people responsible are named. Systemic reforms are possible now, in a way they weren't before.

What You Lost The immediate crisis deepened before it ended. Several innocent people suffered collateral exposure. Trust in institutions collapsed further before it could be rebuilt.

 

FINAL REFLECTION Was full transparency the right choice? What does justice require — the full accounting, or the most lives saved? Is there a meaningful difference between truth as a value and truth as a tool?

 

Choice B: Target Vask, Protect the System

Target the deliberate actor specifically; preserve the institutions.

 

You give Corsley what he needs to detain Vask — enough for an arrest, not enough for a public trial yet. You quietly hand Mira the medical information she needs to treat the biological cases. You tell the Council what they need to authorize the infrastructure repairs, without going into detail about the aqueduct approval document.

The refugees are cleared without full explanation. They'll never know why, exactly. They'll move on.

Things improve. The sick improve.

Vask sits in a cell while evidence is slowly assembled. It'll be enough. Eventually.

What nobody talks about: the aqueduct flaw. It's repaired, quietly. The engineer who flagged it twelve years ago is given a consulting contract. He doesn't know why. He doesn't ask.

Prace survives politically. The systemic failure is buried.

 

What You Gained Thirty-nine of the forty-seven sick recover. Vask is punished. The immediate crisis ends with minimal additional harm.

What You Lost The structural conditions that enabled this — the corner-cutting, the budget decisions, the culture of dismissing safety concerns — remain intact. In twenty years, something like this happens again.

 

FINAL REFLECTION You saved more lives, short-term. You may have made the next disaster more likely. Is that trade a good one? Who gets to make it? Is protecting a flawed system ever ethically defensible?

 

Choice C: Fix the System, Not Just the Symptom

Prioritize long-term systemic change over individual justice.

 

You focus on what you can actually change.

You give the medical information to Mira. You give the infrastructure information to an independent engineer — not the Council. You connect the River Cult's archival records to the city's public works office, establishing a precedent for their knowledge to be formally consulted.

You give Corsley enough to keep Vask detained while you work on the larger picture. You don't expose everything publicly — not yet. You use what you know to force the right decisions quietly.

The aqueduct is repaired. The refugees are cleared. The Fort drainage system is sealed by a joint team that includes, for the first time, a River Cult advisor.

Vask eventually goes free — lack of evidence, eventually. He leaves Thornhaven. He'll try something like this somewhere else. You know that and can't stop it.

But you've changed how Thornhaven makes decisions. Slightly. Incrementally.

 

What You Gained Long-term systemic change. A template for how to handle the next crisis differently. The River Cult's knowledge is formally integrated. The engineering failure is documented.

What You Lost Vask faces no real justice. The individuals most responsible for the infrastructure failure are never formally named. Some people will always believe the refugees were involved.

 

FINAL REFLECTION Wicked problems rarely end with a villain punished and a system healed. Usually it's one or the other. You chose the system. Was that wisdom or compromise? What does justice mean if the most harmful actor goes free?

 

Choice D: Trust Mira to Lead

Give everything to Mira Soldane and trust local knowledge to find the path.

 

You give everything you've found to Mira Soldane.

All of it. The documents, the testimony, your analysis, the barrel's contents, Aldric's log, the aqueduct approval record. You tell her what you think it means and where the connections lead.

Then you step back.

Mira is from Thornhaven. She knows its people, its politics, its fault lines. She knows who will respond to what kind of pressure. She knows which revelation will cause riots and which will cause quiet reform.

She works for three weeks with what you gave her. She saves forty-one of the forty-seven. She gets the aqueduct repaired. She gets the refugees cleared.

She never publicly names Vask — but he leaves the city within a month and never returns. Nobody knows why.

She never forces the Council to account publicly for the aqueduct decision — but Prace quietly endows a public infrastructure safety fund before her next election.

Nobody gets the full story. Nobody gets punished proportionally.

But thirty people are alive who might not have been.

 

What You Gained You trusted local knowledge over outside judgment. You used information as a tool rather than a weapon. The outcome is imperfect but livable. Mira becomes a lasting institutional resource.

What You Lost There is no record. In twenty years, people will tell this story differently — they'll say it was an accident, a mystery, never quite solved. The lessons will have to be relearned.

 

FINAL REFLECTION Is an undocumented outcome that saves lives better than a documented outcome that assigns blame? Who is history for? Does it matter who gets credit for a solution, if people are saved?

 

Part Seven: Debrief — The Nature of Wicked Problems

This section is for use after completing the adventure — in a classroom, a discussion group, or solo reflection. It connects the adventure's structure to the theoretical framework of wicked problems.

 

Defining Wicked Problems

In 1973, design theorists Horst Rittel and Melvin Webber defined 'wicked problems' in contrast to 'tame problems.' Tame problems can be solved using standard approaches: they have clear definitions, finite solutions, and success criteria. Wicked problems cannot.

 

The Ten Characteristics of a Wicked Problem (Rittel & Webber, 1973)

1.       There is no definitive formulation of a wicked problem.

2.      Wicked problems have no stopping rule — you never know when you're 'done.'

3.      Solutions to wicked problems are not true-or-false, only good or bad.

4.      There is no immediate or ultimate test of a solution.

5.      Every solution is a 'one-shot operation' — you cannot undo what you've done.

6.      Wicked problems do not have an enumerable set of potential solutions.

7.       Every wicked problem is essentially unique.

8.      Every wicked problem can be considered a symptom of another problem.

9.      Discrepancies in representing a wicked problem can be explained in numerous ways.

10.   The planner has no right to be wrong — there is real-world accountability.

 

How The Ashrun Affair Embodies Each Characteristic

No definitive formulation

Is this a public health crisis? A crime? A political failure? A systemic infrastructure problem? All of these are true simultaneously — and different stakeholders define the problem differently based on their position.

 

No stopping rule

Even after Vask is identified, the aqueduct remains compromised. Even after repairs, the cover-up is unaddressed. There is always one more thing to fix.

 

Solutions are good or bad, not true or false

Each of the four endings produces some good and some harm. None is 'wrong.' All involve genuine trade-offs.

 

No ultimate test of a solution

Will Thornhaven be safer in twenty years? That depends on whether the systemic conditions change — which is unknowable in the moment.

 

One-shot operation

The choice to expose everything publicly cannot be undone. The choice to protect the system cannot be undone. These are irreversible decisions made with imperfect information.

 

No enumerable solutions

The four endings are illustrative, not exhaustive. Real investigations produce hybrid, partial, improvised responses — not clean categories.

 

Essentially unique

The specific combination of actors, history, geography, and timing makes this problem unlike any other. Generic 'water contamination' solutions miss the specifics.

 

Symptom of another problem

Vask's actions are a symptom of a political grievance. The infrastructure failure is a symptom of a culture of cost-cutting. The scapegoating is a symptom of social division.

 

Explained in numerous ways

The River Cult sees divine judgment. The Watch sees criminal sabotage. The Council sees external competition. The refugees see injustice. Each explanation is coherent and partially true.

 

No right to be wrong

Forty-seven people are still sick during this investigation. Every hour of delay costs real harm. The investigator is accountable to those outcomes.

 

 

Critical Thinking Skills Practiced in This Adventure

Identifying Hidden Assumptions

Every faction in Thornhaven operates from assumptions they haven't examined. The first step in addressing a wicked problem is surfacing these assumptions.

 

Distinguishing Correlation from Causation

The timeline clue explicitly flags this fallacy. The refugees were upstream before the illness — but that doesn't mean they caused it.

 

Evaluating Source Reliability

Each NPC has partial truth and self-interest. Prace's testimony is more reliable when corroborated by Aldric's log; Sable's observations are reliable even though their interpretation is speculative.

 

Systems Thinking

The aqueduct decision twelve years ago and Vask's actions five weeks ago are connected through a chain of decisions no single person made alone. Understanding the system means tracing those connections.

 

Ethical Reasoning Under Uncertainty

Every ending requires choosing between competing goods — transparency vs. stability, justice vs. lives saved. This is the core of ethical reasoning in complex situations.

 

Resisting Simple Narratives

The temptation to find one villain (Vask) and declare victory is powerful. The adventure is designed to reward players who resist this and examine the full system.
