THE TOMB OF ASHKARETH

Your character: You are Bram Coldwell — a scarred mercenary fighter, chainmail dented from a hundred jobs gone sideways. You carry a longsword, a hand axe, a torch, and 30 feet of rope. You have 20 HP.

The job was simple: retrieve a signet ring from a dead nobleman's crypt, proof of inheritance for some lord you've already forgotten. Easy coin, the broker said.

That was three hours ago. Now you're standing at the bottom of a collapsed staircase, the entrance sealed behind you by falling stone. The only way is forward.

Your torch gutters in a damp breeze — which means air is moving somewhere ahead.

The passage splits before you:

A narrow tunnel to the left, low enough you'd have to crouch. The floor is scratched — something was dragged through here recently.

A wider corridor to the right, lined with old burial alcoves. Several of the stone slabs have been pushed outward from the inside.

Somewhere in the dark ahead, you hear a faint sound — rhythmic, wet. Like something feeding.

What do you do?

Type your action freely — no rules to memorize. Just tell me what Bram does.

Might as well get what I came here for. Burial alcoves.

Bram — pragmatic as ever.

You head right, torch raised, boots crunching on grit and old bone-dust. The burial alcoves stretch down both sides of the corridor — maybe a dozen of them. Most are intact, sealed with carved stone bearing faded noble crests.

But four slabs lie shattered on the floor. Those alcoves are empty. Not robbed — the stone was broken outward. Whatever was inside wanted out.

You scan for the signet ring. The broker said the nobleman — one Lord Edric Vane — was interred "in a place of honor." Your eyes follow the corridor to its end, where a larger alcove sits elevated on a stone dais. Fitting for a lord.

You approach. The slab is still sealed. Vane's crest — a hawk clutching a key — is carved above it.

The ring is almost certainly inside.

Here's the problem: the wet feeding sound is louder now. It's coming from the narrow tunnel to your left — the one that connects back to this corridor about twenty feet ahead of you. You can see the tunnel's exit from here, a dark mouth in the wall.

The slab will take ten, maybe fifteen seconds to shift.

Noisy work.

Do you:

  • Muscle the slab open now and grab the ring fast?
  • Investigate that tunnel exit first — make sure nothing's about to come through it?
  • Something else entirely?

Draw sword. Go toward the sound.

Now we're talking.

Steel scrapes leather as Bram draws his longsword. You plant the torch in a wall sconce — better to have two hands free than to see a little farther.

The corridor dims. You advance on the tunnel mouth.

Ten feet away. The feeding sound is loud now — wet tearing, the crack of something small. The smell hits you: rot, copper, and something animal.

You stop at the tunnel entrance and look in.

Crouched over the gnawed remains of a grave rat, its back to you, is a ghoul. Hairless, grey-skinned, fingers like iron nails. It hasn't heard you yet — too absorbed in its meal.

But you can see past it down the tunnel. There are two more shapes huddled further back, dormant. Sleeping, maybe. The ghoul in front of you is between you and them.

Three total. One aware, two not — yet.

Bram's an experienced fighter. You recognize the tactical reality immediately: if this one shrieks, the others wake up. Ghouls hunt in packs and their claws can paralyze a man. Three-on-one in a cramped tunnel is a bad death.

But you have surprise. Right now.

What's your move?

The tunnel is low — no big swings. You have a hand axe too. And that rope...

Plant the sword in its spine.

This is what mercenaries are for.

You shift your weight forward, sword leveled low for the cramped ceiling. Three steps — slow, heel-toe, silent — and you're close enough to smell the grease on its skin.

You drive the blade home. Hard. Between the shoulder blades, angled up.

The ghoul spasms violently — a horrible convulsion — and you clamp your free hand over its jaw before the shriek can escape. It bites down. Your gauntlet holds. Barely.

It goes limp. You lower it to the ground with agonizing slowness.

Silence.

You look up. The two shapes further down the tunnel — motionless. A long breath. Five seconds. Ten.

Still sleeping.

You ease backward out of the tunnel, ghoul blood dark on your sword. Your hand is shaking slightly, but that's just the cold. Sure it is, Bram.

Back in the corridor. Torch still burning. The sealed alcove waits on its dais — Lord Vane, undisturbed.

But you're now thinking clearly about something: four empty alcoves. One ghoul dead. Two more sleeping. That's only three.

The fourth alcove is unaccounted for.

You haven't heard anything from deeper in the dungeon. Yet.

Do you:

  • Grab the ring now — fast, then find a way out?
  • Put down the two sleeping ghouls first — clear the tunnel?
  • Listen — try to locate that fourth one before it locates you?

Put down the two sleeping ghouls first.

Bram thinks like a survivor. Good.

You wipe the blade on the dead ghoul's leg, take one steadying breath, and duck back into the tunnel.

The two shapes are visible now — slumped against the tunnel wall, side by side. Skeletal chests rising and falling in shallow, irregular rhythms. Ghoul sleep looks almost peaceful. Almost.

You approach the first one.

Same technique. Blade positioned. You've done this before — not to ghouls, but the principle is the same as any sleeping sentry. Don't hesitate. Commit.

You commit.

Clean. It shudders and goes still without a sound.

You pivot to the second—

Its eyes are open.

Yellow. Filmed over. Staring directly at you.

It was already awake. Waiting.

It lunges — fast, faster than the first one, swiping at your forearm before you can fully react. The claws rake across your chainmail, one finding the gap at your wrist.

A line of fire across your skin. 3 damage. 17 HP.

But you're a fighter, not a victim. The lunge brought it onto your blade. You drive forward on instinct, pinning it to the tunnel wall. It writhes, hissing, claws scrabbling at your arms—

You twist. It drops.

Silence floods back in.

Your wrist is bleeding. Not badly — but ghoul scratches have a reputation. You'll want to clean it soon.

Three down. The fourth still unaccounted for.

You back out of the tunnel into the corridor.

The torch is still burning. The dais is right there. Lord Vane's alcove, sealed and waiting.

And then — from somewhere below — you hear stone grinding on stone. Slow. Deliberate.

There are stairs at the far end of the corridor you hadn't reached yet. Leading down.

Something is coming up them.

Do you:

  • Grab the ring right now — thirty seconds, damn whatever's on those stairs?
  • Stand and meet it at the top of the stairs — control the chokepoint?
  • Douse the torch — fight in the dark and use sound?

Quick and quiet, move to a point beside the stairway opening. Ready to strike.

Textbook. Let it come to you.

You move fast — low, quiet, torch grabbed and smothered against the stone floor until it gutters out. Darkness swallows the corridor whole.

You press your back against the wall, two feet from the stairway opening, sword ready at your side. Not raised — raised means telegraphing. You'll bring it up at the last half-second.

You listen.

The grinding stops. Footsteps now — heavy, irregular. One set. Whatever it is, it's alone. It climbs slowly, like it's been underground a long time. Like it's remembering how legs work.

A shape emerges from the stairway.

Taller than the ghouls. Dressed in the rotted remains of noble clothing — a hawk crest barely visible on the breast. Grey flesh pulled tight over a gaunt frame. Its eyes are pale blue and luminous, faintly illuminating the dark around it.

Not a ghoul.

A wight. Lord Vane himself, by the look of it. Which means the alcove upstairs is empty — has been for some time. The broker sent you into a dead man's tomb not knowing the dead man still walked it.

Vane hasn't spotted you. He's moving toward the corridor, toward where his ghouls should be.

You have one clean strike before he knows you're here.

Wights are dangerous — they can drain the life from a man with bare hands. But they can also be dropped if you hit hard enough, fast enough.

Your sword arm tightens.

Do you:

  • Strike now — everything you've got, one devastating blow?
  • Wait — let him move further into the corridor, get a better angle?
  • Speak — sometimes the undead can be reasoned with. Stranger things have happened in tombs.

Speak: "Why does Lord Vane yet walk the halls of his tomb?"

Bold. Very bold.

You keep the sword ready but let your voice come out low and steady — the tone of a man who isn't surprised, even when he is.

Vane stops.

Those pale blue eyes sweep the darkness and find you with unnerving precision. He can see in the dark better than you can. He's been watching you for a moment already, you realize. The slow climb, the deliberate pace — he knew you were there.

A long silence. Then he speaks.

His voice is like a door that hasn't been opened in decades.

"The same reason you will."

He tilts his head — almost curious. Almost human.

"You carry the broker's coin. Aldric Mourne sent you." Not a question. "He has sent seven before you. He wants the ring because the ring opens the vault beneath this tomb. He told you nothing of the vault, I suspect."

The pale eyes drift to your bleeding wrist.

"The scratch. You killed my children in the tunnel." No anger in it. Just acknowledgment. "Mourne will send more when you don't return. He always does."

Vane takes one slow step toward you. You hold your ground — barely.

"I do not want to add you to my household, mercenary. You fight well and you think before you act. Rare qualities."

Another step.

"So I will offer you a choice instead."

The tomb is very quiet. Your wrist is burning.

Do you:

  • Listen to the offer — you're already curious about that vault
  • Attack mid-sentence — you don't negotiate with wights
  • Ask about Mourne — who is this broker, really?

"I'm listening."

Vane regards you for a moment that stretches uncomfortably long.

Then he moves — not toward you, but past you, down the corridor with that slow, deliberate gait. He expects you to follow. It's not arrogance exactly. It's the certainty of something that stopped fearing consequences a long time ago.

You follow. Sword still drawn.

He stops before his own empty alcove and looks at it the way a man might look at an old portrait of himself.

"Aldric Mourne is not a broker. He is a collector of forgotten powers. This ring—" Vane raises his right hand. The signet ring — hawk clutching a key — is on his finger. He never removed it. "—opens a vault I sealed before my death. Inside is something Mourne has wanted for thirty years."

"A Codex. Written in a dead language. Instructions for binding souls to a place permanently. Not undeath as I am — something far more permanent. Far more useful to a man who trades in leverage."

The pale eyes fix on you.

"I cannot leave this tomb. That is my limitation. But you can. Bring Mourne the ring — I cannot stop you — and he completes his work within a year. Or—"

He reaches into his rotted coat and produces a second ring. Plain iron. Unremarkable.

"Deliver this to a woman named Sera Voss in the city of Dunhaven. She'll know what it means. She has been fighting Mourne far longer than you have known his name."

He holds it out.

"I am already dead, mercenary. I have no use for heroes. But I have use for someone Mourne doesn't know is working against him."

Your wrist throbs. The torch is dead. You're standing in the dark negotiating with a corpse.

What does Bram do?

"I am no hero, Vane. You have named me well. I am a mercenary. What shall be the reward for delivering the ring to Sera Voss in Dunhaven?"

A sound escapes Vane that might once have been a laugh.

"Spoken honestly. I respect that more than courage."

He considers you with those luminous eyes. Calculating. Whatever he was in life — and the hawk crest suggests old money, old power — he was a man who understood transactions.

"Mourne offered you coin. I will not insult you with the same."

He reaches back into his coat. Produces a small iron key, old but perfectly preserved, and holds it alongside the plain ring.

"Beneath the third flagstone left of this dais is a strongbox. My personal treasury — what remained when I died. Four hundred gold crowns. Yours now, before you leave this tomb. Proof of good faith."

He sets the key on the edge of the dais.

"Additionally. That scratch on your wrist." His eyes drop to it briefly. "Ghoul wounds fester in ways physicians don't understand. Sera Voss will know the treatment. Consider that — your continued health — part of the arrangement."

He pauses.

"And when Mourne falls — because he will fall, Sera has been building toward it for years — there is a second vault beneath the first. One Mourne doesn't know exists. Its contents I leave to whatever agent delivers his end."

He extends the plain iron ring toward you again.

"Four hundred crowns now. Your health. Whatever is in that second vault later. And the satisfaction of having ruined a man who used you as expendable."

The ring waits in his dead fingers.

"I would call that competitive rates for a mercenary."

Your wrist is definitely burning more than it was.

Bram's move.

"A generous offer and the promise of more adventure. I will fulfill this quest." Accept the iron ring and take the key.

And just like that, Bram Coldwell has a new employer.

You take the iron ring — cold, heavier than it looks — and pocket it carefully. The key follows.

Vane withdraws his hand and steps back. Something in his posture shifts, almost imperceptibly. Relief, maybe. The body language of a man who has been waiting a very long time for someone to say yes.

"The strongbox is where I said. Take what's there — all of it. You've earned it already tonight."

He turns back toward the stairs.

"One warning, mercenary." He doesn't look back. "Mourne will know you entered this tomb. He always watches his investments. When you don't return with the signet ring, he'll send someone after you."

"Don't go back to whoever hired you on his behalf. Don't sleep where you slept last night."

"Find Sera Voss first. Everything else follows from that."

He descends the stairs. The pale blue light fades with him. You're alone in the dark.

You find the torch, relight it with your flint. Third flagstone left of the dais — you count, press, and feel it shift. The strongbox is there. Iron-banded, locked tight.

The key turns smoothly.

Four hundred gold crowns. Neatly stacked. Vane was a man of his word, at least.

You pocket the iron ring, shoulder the strongbox, and start looking for another way out of this tomb — because the entrance is rubble and Bram Coldwell did not survive this long by leaving the way he came in.

Twenty minutes later you find a drainage passage behind a false wall near the tunnel. Cramped, wet, smelling of old earth. It opens onto a hillside half a mile from the tomb entrance, cold stars overhead, the lights of a distant town flickering in the valley.

Dunhaven is three days east.

Your wrist burns.

You set off into the night.

SESSION COMPLETE

That was a tight, well-played hour, Bram. You ended with:

  • 400 gold crowns
  • The iron ring for Sera Voss
  • Three ghouls dead, one wight allied
  • A festering wrist and a powerful enemy in Mourne
  • A mysterious second vault waiting at the end of the road

Want to pick this up another time and ride for Dunhaven?

What the Dead Keep

The first is Bram's story — a simple job that wasn't. The second is Vane's — a secret held in a tomb for decades, waiting for the right mercenary to walk in.
