The premise

The Priory of Saint Cordula sits on a shelf of rock above the Greave Pass, a day's climb from the village of Tarnwick, on the last consecrated boundary before the Unhallowed lands. Every dusk the brothers light a fire on the bell tower so Tarnwick knows they are alive. Three nights ago the fire did not burn.

What Tarnwick does not know: in autumn the brothers cut a figure out of the glacier above the priory. It was a man, or shaped like one, kneeling, perfect, with frost on its eyelashes. The Prior called it the Ice Saint and sent to Aubrecht for a canon to certify it. Pilgrims would come. The priory would be rich.

It was not a saint. The brothers laid it in the chapel to thaw. Old Brother Faustin sat vigil beside it through the night, alone. By morning the ice coffin was empty and Faustin said he had seen nothing.

It is called the Guest in this book, because that is what it does: it comes in, sits at your table and wears a face you know. It can become anyone it is left alone with for long enough. Every piece of it is all of it. Fire is the only thing that ends it.

The hook

The heroes are in Tarnwick when the fire fails for the third night. The reeve pays them a purse of clipped coin each, with a promise of more in spring, to carry the winter supply up to the priory and come back with news. They lead one mule: lamp oil, salt, flour and candles.

“If the fire burns on the tower when you get there, they've only run out of oil. Give them ours and come down. If it doesn't burn, come down faster.”Reeve Mathilde Sallow of Tarnwick

Make sure the players know two things before play: the pass closes in heavy snow, and nobody will come looking for them until spring.

The shape of the adventure

  1. The Last Lamp. Arrive in a storm, get inside, meet the survivors, find the empty coffin. The pass closes behind them.
  2. The Byre. The first night. The animals scream. Something is wearing Brother Odo, badly. Now everyone knows it copies people.
  3. The Cut. Climb to the dig on the glacier and learn what the Guest is, and the one test that tells it apart. Come back to find the gate barred against you.
  4. The Chapter House. Everyone is tied to the benches and tested, one at a time, while the fire burns down.
  5. The Icehouse. What is left of the Guest has gone below, among the winter dead, and is boring its way down the mountain towards Tarnwick. Burn it, or warn the valley, or both.

Who is the Guest at the start? Brother Faustin. He has been the Guest since the night of the vigil. In scene 2 a piece of him is taking Brother Odo in the byre. When the Horror first reaches 7 (or at the start of scene 4 if it has not), the Guest takes a second person: use the roster below. Keep both secret until the blood says otherwise.


What the Guest is and does

Nobody on the mountain knows where it came from. The ruin it was frozen in, Ossk Varel, is older than the Binding and has no name anyone can read. Do not explain it further. The less the players know, the better this works.

Its rules

Fire at the table

The rules do not have a fire rule, so here is a ruling for this adventure. A burning brand is a Close weapon: STR check, Basic Effort d4, and it counts as fire. A lit Flask of lamp oil thrown into Close or Near is a DEX check; on success roll Basic Effort d4 and the target is burning: it takes d4 at the start of each round until it spends an Action smothering itself in snow. Track burning by hand. Spells such as Ember, Ember Psalm, Pyre and Kindle count as fire, and each non-healing spell still adds its 1 Horror. That cost should hurt here: fire is exactly what the heroes need, and magic is the quickest way to get it.

The Horror, in this adventure

The table alerts you at 7, 14 and 21; you choose what happens. Suggested choices:

HorrorWhat the Guest does
7It stirs. Before the next scene the Guest takes a second person (the roster). Somebody is quieter than before.
14It draws near. The lamps fail. The oil store is found poured out into the snow. From now on the only light is what the heroes carry, and every WIS check to search or notice in the dark is Hard (as the Hooded Lantern describes).
21It has arrived. In scene 5 the Gathered Guest has 20 more HP and the countdown starts one lower. If a player agreed to the Taken Hero option, their hero is now taken.

Optional, for the paranoia: when the heroes kill or burn someone who turns out to be human, raise the Horror by 2 by hand in the Table tab. Say so before play.


The priory

A tight cluster of grey stone round a square cloister yard, the snow in it waist-deep. Every building is a short walk through the cold from every other, and every walk is a moment someone is alone.

Map of the Priory of Saint Cordula: buildings around a cloister yard, the glacier path to the north, the lower road and rope bridge to the south to the Cut · the glacier lower road · rope bridge · the pass Chapel of Saint Cordula the empty ice coffin Belltower fire Chapter House scriptorium above 4 cloister yard Infir-mary Dormitory the dorter Refectory · kitchen icehouse below 5 Gate 1 Byre · stores goats, mules, oil 2 3
Numbers mark where each scene happens. The bell tower is reached from the chapel; the icehouse by a trapdoor in the kitchen floor.
PlaceWhat is there
GatehouseAn oak gate with a bar on the inside and a spyhole. The porter's cell beside it is empty, the blanket folded.
ChapelCold as the yard. The ice coffin lies before the altar on two trestles, split open from the inside. Meltwater has frozen again on the floor in a long smear towards the vestry door. One window pane is broken; a fragment of stained glass lies in the frost.
Bell towerA ladder from the chapel, a platform with an iron fire basket. The basket holds cold ash and a cracked oil jar. Three fire baskets in a row, the old signal, mean plague: stay away.
Chapter HouseStone benches round the walls, one hearth, the priory's books upstairs in the scriptorium. The only room with a door that bars from inside on both sides.
InfirmaryBrother Lucan's room. Herbs, a physician's satchel, a slate covered in his notes about the Ice Saint.
DormitoryEight cells off a corridor. Faustin's cell is very tidy. Under his straw mattress: his own spectacles, which he has not asked for.
Refectory and kitchenThe warm room. A long table where everyone eats, so everyone can watch everyone. A trapdoor in the kitchen floor leads to the icehouse, where the brothers keep the winter dead until the ground thaws.
Byre and storesGoats, two mules, hay, the oil barrels. Ursel sleeps in the loft.
The CutAn hour's climb up the glacier: the dig, a lean-to of tools, and the black mouth of the ruin in the ice.
Lower roadThe way home: a rope bridge over a gorge, then the pass. In snow it is a day to Tarnwick. Once the pass closes, it is a spring away.

The people

Eight people are alive at the priory when the heroes arrive. Tick a box when someone is taken; it is only saved in your own browser.

Prior Severin Ashby

Proud, tired, charming. Ordered the dig. Wants the Ice Saint to be real, because he has already spent the money it would bring. Will lie to protect the priory's name.

Brother Lucan Tarn

The infirmarian. Clever, frightened, thorough. The first to understand. After scene 3 he decides nothing must leave the mountain, and he means nothing: he burns the rope bridge and bars the gate. He is never taken unless you choose; he is the dangerous human.

Brother Faustin Mourne

The old scribe, half-blind, gentle. Kept vigil over the Ice Saint. The Guest from the start. Tell: he reads small writing without his spectacles.

Brother Odo Wick

Cellarer and cook. Big, kind, laughs too loudly when scared. Being taken in the byre during scene 2.

Brother Dunstan Crane

A novice of fifteen who keeps the bell and the tower fire. He let the fire go out because Brother Faustin told him the Prior had forbidden it. He is ashamed and will not say so.

Canon Hildreth Vesper

Of the Order of the Vault, sent from Aubrecht to judge the Ice Saint. Cool, exact, unafraid. Secretly carries a Vault specimen jar holding a piece of the Ice Saint, cut off in autumn. The Order wants a live one for the Undervaults.

Ursel the Goatherd

A lay servant, fifty, hard as a boot. Trusts the goats more than the brothers. A natural ally, which is exactly why she is worth taking.

Jorun the Muleteer

Brought the Canon up and wants his pay and his road home. Quick to anger, quick to accuse, carries a crossbow. Will try to leave by the lower road at the worst possible moment.

The second Guest

When the Horror first reaches 7, or at the start of scene 4, roll a d6 to see who else the Guest has taken. Roll again if that person is dead or already shown to be human.

d6TakenHow it happened
1Prior SeverinHe went to pray in the chapel alone. Faustin followed to keep him company.
2Canon HildrethShe opened her specimen jar to look. The piece was waiting.
3UrselShe went out to the byre to calm the goats.
4JorunHe tried the lower road, came back an hour later, and said the bridge was out.
5Brother DunstanHe climbed the tower to light the fire against orders.
6Your choiceA hero, if a player agreed to the Taken Hero option. Otherwise choose whoever would hurt most.

Running the paranoia

The fights are short. The real game is the talking between them. A few habits keep it frightening:

The Taken Hero (optional, ask first)

Before play, ask privately whether one player would enjoy their hero being taken. If they say yes, and only then: when you choose, write in that hero's private notes on the table (only the owner and the GM can see them) “You were alone in the dark for too long. You are the Guest now. Nobody must know until you choose.” The player keeps playing their hero, keeps rolling honestly, and wins if the Guest gets down the mountain. Their blood fails the test. Never do this to a player who did not agree.

The Last Lamp

Target 12Gatehouse, chapel, refectoryArrival, introductions, the empty coffin

The snow has been coming sideways since noon. The mule is stumbling. Above you, the priory sits on its shelf of rock like a fist, and the bell tower is dark. The gate is shut. Drift is piled against it to the height of a man, and behind you, down the pass, you can hear the mountain moving.

Nobody answers the gate at first. The porter is gone. The heroes have to dig and force their way in while the storm closes the pass behind them.

Obstacle
The Drifted Gate
Progress
0 / 20 Effort
Check
STR to dig and heave

Snow to a man's height, and the gate barred from inside.

A Wayshrine Crowbar makes the STR check Easy. A Rope and Grapnel gets one hero over the wall as a Move; they can then lift the bar and the obstacle is done. Someone inside (Ursel) lifts the bar if anyone shouts for 2 rounds straight.

Countdown
The Pass Closes
Rounds
4, automatic

The mountain is moving. The road behind you will not be there long.

At 0 a snow shelf comes down across the lower road. Anyone still outside the gate takes d6 as the edge of it buries them. If the mule is not inside by then, it bolts down the pass with the supplies: the oil, candles and salt are lost.

Inside

Ursel lets them in, or finds them in the yard, with a goat-knife in her hand. She takes them to the refectory, where the survivors are gathered round the only fire they still trust. Let the players meet everyone in one room, at one table, so they can watch faces.

The chapel

If the heroes ask about the Ice Saint, or wander, they find the chapel. The coffin is split from inside. The frozen smear on the floor runs to the vestry door and stops. The vestry is empty: robes on hooks, one of them missing.

The missing robe is the one Faustin wore at the vigil. It is in the icehouse, under the dead, with the porter: the first person the Guest killed, two nights ago, when he caught it trying the gate. The heroes cannot know that yet.

Loot · hidden
Fragment of stained glass

A shard of blue glass in the frost under the broken window.

Catalogue relic, 1 Horror. Looking at the coffin through it shows one image from the last day: an old brother's hands flat on the ice, and the ice pressing back.

Loot · hidden
Brother Lucan's slate

A slate covered in small chalk writing.

Story item, no rules. “Wept for nine days in the coffin. Not meltwater. Too warm. Hair grew. It was not dead. It was not sleeping either.”

Leaving the scene

End with the first night. The Prior offers the guest cells in the dormitory. Ask each player where their hero sleeps, and with whom. Ask who keeps watch. Then let it be quiet for a while.

Rest: a Party rest is fine tonight, if the heroes keep a watch. If nobody watches, the Guest does not take a hero tonight, but tell the players nothing either way.

The Byre

Target 12Byre and stores, the yard at nightFirst fight, the first proof

You wake in the dark to the goats. Not bleating. Screaming, the way an animal screams when it cannot get out. Across the yard there is a lamp moving in the byre, and the shadow of a big man bent over the stalls, and the shadow is wrong. It has too many elbows.

Brother Odo went out to the byre with a lamp because the goats were restless. A piece of Faustin was waiting in the hay. The heroes arrive halfway through. Odo's face is still Odo's; the rest of him is opening like a book.

Countdown · paused
The Byre Burns
Rounds
3, start it when the hay catches

Hay, timber, lamp oil. It will go up fast.

Fire is the obvious answer, and the byre is a tinderbox. Start this countdown when anything burns. At 0 the roof comes down: anyone still inside takes d6, and everything left in the byre burns, including any Crawling Piece. The oil barrels go up too, which matters at Horror 14.

Running it

After the fire

Brother Lucan kneels in the ash with tongs and lifts out something that is still moving. Now everybody knows: it can look like anyone. The Prior wants to pray. Jorun wants to leave. The Canon wants the thing in the tongs, very badly, and asks for it in a level voice.

If the Canon gets it, put it in her specimen jar. That raises the chance she is taken (she is 2 on the d6 table already) and gives you a second Guest to release at a bad moment.

Loot · hidden
Odo's keys and lamp

A ring of cellar keys, and a Hooded Lantern with one cracked pane.

The keys open the oil store and the icehouse trapdoor. The lantern is the catalogue Hooded Lantern.

Loot · on the table
Flasks of lamp oil

Two flasks on a shelf by the stalls.

Two catalogue Flasks of lamp oil, if the byre has not burned. Thrown alight, use the fire ruling above.

Rest: the heroes can take a Party rest before dawn, in the refectory, with everyone watching everyone. A rest here is a fine moment for the Horror to reach 7.

The Cut

Target 13The glacier, the ruin of Ossk Varel, the barred gateWhat it is, the test, shut out

Brother Lucan says the answer is at the dig. The brothers' notes stop on the day they found the figure; something else was down there, and the Prior had the tunnel boarded up. Lucan cannot climb. The heroes can. Ask who stays behind. Jorun or the Canon will come if asked; Faustin offers, and should be refused, with a smile.

The glacier is blue inside. Your breath freezes on your scarves. At the top of the climb there is a lean-to of picks and planks, and a tunnel the brothers cut, boarded across. Someone has pulled the boards out from the inside.

Obstacle
The Ice Stair
Progress

Check
STR or DEX

Steps cut in the ice by the brothers, half filled with new snow.

A failed check costs the climber d4 from a fall or the cold, which nothing reduces. A Rope and Grapnel lets the whole party skip this as one Move, as its own text says.

Countdown · paused
The Ice Weeps
Rounds
3, start when a flame comes Near the far wall

Water runs down the wall in thin lines where your light touches it.

A second figure is frozen in the far wall. Heat wakes it. At 0 it breaks free: add the Sleeper in the Wall. Working by no light keeps it asleep, but every WIS check to search or read in the dark is Hard.

Reach
Close

Half a shape, still sheathed in ice to the waist.

Slow from the cold: it acts last in each round and cannot leave the wall for its first 2 rounds. Same breaking and burning rules as every Guest form. If it is not burned, it follows them home.

What is in the ruin

Beyond the boards: a round chamber of black stone, older than anything the heroes have seen. Around the walls, in the ice, are people. Twelve of them, sitting in a ring, facing inward, dressed in nothing anyone can name. In front of each one is a stain in the ice, bright red, and the stains are not frozen. They are still wet after all these centuries.

Carved on the centre stone: a row of figures, each one holding out a cut hand over a white field. Under most hands the drops lie still. Under two, the drops have stood up and are running towards each other.

Learning the test

Any of these teaches it:

The test. Human blood dropped on snow freezes into a dark crust within a breath. The Guest's blood does not freeze. It stays bright and wet, and then it slides across the snow towards the nearest other part of the Guest. A test can expose two at once. It needs snow, a blade and light to see by.

Loot · hidden
Pre-Binding coin

A coin of black metal from the floor of the ring, too heavy for its size.

Catalogue valuable. The GM decides its worth in Aubrecht. The Canon will want it.

Loot · roll
The diggers' lean-to

Picks, planks and a frozen pack.

Roll once on the d100 loot table, or give the Wayshrine Crowbar and Iron Spikes and Hammer.

Coming home: the gate is barred

It is nearly dark when you reach the priory. Smoke is rising from the lower road, where the rope bridge was. The gate is shut. Brother Lucan's voice comes through the spyhole: “How long were you up there? Were you ever apart? Then how do you know?”

While the heroes were gone, Lucan burned the bridge and poured out half the oil so nobody could use it to leave. He is not taken. He is right, and he is terrified.

Obstacle
The Barred Gate
Progress
0 / 30 Effort
Check
STR to force it

Oak, barred and spiked from the inside.

Lucan has spiked it, so forcing it is Hard. The other way in is talk: a Hard CHA check to persuade him, which ends the obstacle at once. Offering to be tested at the gate is worth making the check Normal instead. Someone inside may open it for the heroes; who offers is a good place to plant suspicion.

Countdown
Night Falls
Rounds
4, automatic

The light is going, and the cold is coming with it.

At 0, each hero still outside takes d4 cold at the start of every round. A hero in a Pilgrim's Cloak or under the Winter Shroud takes none (GM ruling).

No rest between scenes 3 and 4. Lucan will not allow anyone to sleep until everyone has been tested.

The Chapter House

Target 12The Chapter House, everyone presentThe test, the reveal, a fight among the bound

Everyone alive goes into the Chapter House. Lucan bars the door. He has rope and insists everyone is tied to the stone benches by one wrist, heroes included, except whoever does the testing. A bucket of snow sits by the hearth. The hearth is the only light.

Roll for the second Guest now if the Horror has not reached 7.

Everyone left alive, on stone benches, one wrist each tied to the iron rings that once held the brothers' book-chains. The fire spits. Brother Lucan holds out a knife, handle first. “I do not trust my own hand,” he says. “Someone else must cut me first.”

Countdown
The Last of the Oil
Rounds
6, automatic

The hearth is burning the last oil and the benches' kindling.

At 0 the fire is out. The only light is what the heroes carry; without light the test cannot be read at all. At Horror 14 or more, start it at 4.

The test, one person at a time
Blood on snow
Cost
one Action per person
Check
WIS to read it

Cut, drip, read. With good light, a Normal WIS check against the Target. In poor light, Hard. A success reads the blood clearly. A failure means it is smeared or unclear: test that person again. A hero's natural 1 also smears it. It is a plain check, so the natural 1 adds no Horror.

Who goes first

Let the players choose the order and argue about it. The NPCs push: the Prior insists on going last, as befits his office. Jorun insists the heroes go first since they were away. The Canon asks quietly that her jar not be opened. Lucan goes first if allowed, and is human.

The reveal

The Guest does not wait to be tested. When the knife is one person away from a taken one, or when the countdown reaches 2, it unveils. If the second Guest's blood is tested first, Faustin's drop slides across the snow to it, and both unveil together.

The Icehouse

Target 14Below the kitchen, the bell towerThe finale: burn it, warn the valley

The ladder goes down into blue cold. The brothers keep their winter dead here, wrapped and stacked like cordwood until the ground softens. The stacks have been pulled apart. At the far end, where the old meltwater channel drains away under the mountain, something has made itself out of them. It is very busy. It is digging.

Everything left of the Guest has gone below and gathered into one body, built from the dead. It is boring along the meltwater channel, which runs under the mountain and comes out in the spring above Tarnwick. If it reaches the village, the heroes have lost.

Oil, timber shoring, straw, and a ladder up.

Roll the oil barrels down from the stores (STR), pour them across the floor (DEX), knock out the shoring so the roof falls in (INT or STR). When it is complete, the icehouse goes up: the Gathered Guest takes 20 damage at once and is burning (d6 each round) and cannot reach the channel through the fire. Anyone still below at the end of the next round takes d8. If the byre burned in scene 2, the barrels are gone: the obstacle needs 40.

Three iron baskets on the tower, iced over.

Clearing and lighting all three on the bell tower tells Tarnwick: plague, stay away. Whatever happens below, nobody from the valley comes up. If the Guest gets away, the village has warning; it is Brother Dunstan's idea, if he lives.

Ways to win


Endings

IfThen
The Guest burned and every piece was foundThe heroes and whoever lived wait for the thaw in the chapel, the only roof left. In spring Tarnwick comes up and finds them thin and quiet. Nobody sits alone with anyone, ever again.
The Guest burned, but a piece escaped somewhereThe same, except you know, and they do not. Tell the players nothing. Keep a note.
The Guest reached the channel, the three fires burnedTarnwick saw the fires and barred its gates. It may be enough. Begin the next adventure in the valley.
The Guest reached the channel, no firesIn spring the reeve sends a letter up the mountain thanking the heroes for the oil. It is in her handwriting. It is very warm in tone.

The last image

Whatever happens, end on two survivors sitting in the snow outside the burning building, watching each other across the fire. One of them offers the other a drink. Ask the player whether their hero takes it. Then stop.
