Nahu Serrin

The campaign’s antagonist · why he hunts Pact-breakers · the night it starts from

At a Glance

Who: An Inquisitor of the Sanguine Inquisition, House Unåia
What he does: Interrogates suspects in their sleep — which is itself a violation of the Pact, and he knows it
Why: At twelve he chose not to send a soul on, because he did not want to say goodbye. It killed Kalda, the village he grew up in, which stands in ruins
The sin: Not fear and not a cover-up. Grief, indulged on purpose, which his own culture names as the selfish thing
He carries: An åsan. Replaced when it goes stale. Every day, for fifty years
At the table: Description, mannerisms, Wants / Needs / Has and Standing are on the run-sheet — this page is the why

The night

Two children are somewhere they have been told not to go, outside the village of Kalda. Ilsa is the bold one — casual about everything, never once caught — and she goes off the rocks. There is no curse in it and no spirit and no punishment. It is an accident of the ordinary stupid kind.

Serrin has an åsan in his pocket. Every child does. He knows exactly what it is for.

He does not use it. He tells himself he will tomorrow.

And then he goes back. She is still there, because nothing has sent her on, and they talk the way they always did. So Serrin comes again the next day, and the day after. It runs for days, and then a week or two — no longer than that. It is not a cover-up and it is not panic. It is a boy who has found a way not to lose someone.

He watches her change. That is the part he has never told anyone. Across those visits Ilsa gets colder, and hungrier, and less like herself, and less interested in the talking — and Serrin keeps going back anyway, because each visit is still more than none.

Then one day he goes down there and the place is empty.

He runs back to Kalda, and he is in time to see it. His mother and his father, the street, the people up and down it. And it is recognisably Ilsa, which is the detail that ends the argument he has been having with himself for a fortnight.

It does not touch him. He has never known why. There is nobody left to ask.

Kalda was never rebuilt. It stands in ruins, and nobody has settled it since.

And nobody said the words over the dead. The village went in a night, there was no one left to perform a rite, and no one has ever come back to do it. So Kalda is not only ruins — every person who died there is still there, unsent. A field of failed transitions, which is the precise condition that made Ilsa, at the scale of a whole village, produced by one boy’s decision not to say goodbye.

Later — intent, not a plan

They learn it by dreaming it. All cold opens are shared memories — he has been in theirs — and one of them is his. Then the party goes to Kalda and sends the dead on, doing the thing Serrin could not. They are already carrying the means: session 0 puts an åsan in each of their hands, for the road. Nothing about how they get there, what they meet, or what it costs is written yet.

The åsan

What it is, in canon

A small white bun, thrown into the water for a soul with nobody to see it off — an offering not of piety, but of pragmatic appeasement… to entice a lost shipmate’s spirit to begin its journey toward Labyrinth, and, more selfishly, to keep it from becoming another hungry echo in the depths. It needs no rank and no Animist. A child can do it. That is the point.

He carries one now, and has for fifty years. Bread does not keep, so it is not the same åsan — he replaces it when it goes stale, has done so several thousand times, and has never once been in a position where he needed it. He does not explain the habit and does not think of it as sentiment. It is the correction, carried.

Session 0 puts the same object in the party’s hands: an åsan each from the Speaker’s basket, given not taken, “for the road.” Four people are walking around Onda carrying the exact thing he did not use.

What it makes him

He is absolute about rites. He is the only person he has ever met with proof of what an unperformed one produces.
He writes everything down. An unrecorded death is an unsent soul. The notebook is not a threat; it is penance.
He cannot accept “I meant well.” He meant well. He meant well for a fortnight, and watched it change, and went back.
He does not believe in his own innocence, and never has — which is why walking a sleeper’s memory does not trouble him the way it should. He decided what he was a long time ago. The arithmetic is just arithmetic now.
He will not be talked out of a rule by someone he loves. It has been tried exactly once.

The scene this sets up

Session 0 is explicit that Isa Varga’s grief is not the cause of the rite failing, and that no player should leave believing it was her fault. Serrin will look at a daughter grieving her father over a casting off that did not take, and reach the conclusion his whole life has trained him to reach. He will be wrong, the party will know he is wrong, and he will not be able to hear them.

At the table

How he behaves in a room — description, mannerisms, the tell, Wants / Needs / Has, Standing, and how to play him — lives on the module run-sheet and is not restated here. The order he belongs to, and how a party recognises one of them, is the Sanguine Inquisition.

Not decided

Ilsa has no family name, and her people are not described.
Where Kalda is, and whether Serrin will say the name. The ruins are a real place someone could walk into; nothing yet says where, or who else knows what happened there.
Why it spared him. Mindless luck, or something in her that still knew him. He does not know, and the page should probably never say.
Where she went afterwards. Canon holds that a spirit which has departed cannot cross back while Umir stands — but nothing here says she departed.
How the sleep-walking came to him. Untouched. Nothing above depends on it.
How he is solved. Left open on purpose — exposure, becoming what he hunts, or winning and being billed for it all remain available.
How the Kalda dead are quelled, and by how many åsan. Four buns is not a village. Whether it needs a Speaker, a rite the party cannot perform alone, or something else is unwritten.
What the party is doing there, and whether Serrin knows they went.

What is frozen

Everything above is 🌊 Fluid. It stands on these 🔒 Canon facts, which are not:

U’Naim Ana — a spirit that falters on its path, clinging to the mortal world out of rage, sorrow, or unfinished business, becomes an Ino. Canon is deliberately vague about the rest; the one thing it fixes is that a soul not sent off properly can turn. The åsan is canon’s own named remedy.
U’Naim Ana — Death is not an end to be feared or mourned with excessive grief, which is seen as a selfish indulgence. Serrin did the named thing, knowingly, for a fortnight.
Social Customs — a proper burial is not just tradition; it’s a vital civic duty. What he withheld was not a kindness he forgot. It was an obligation he declined.
