Overview
Kaelthorn the Undying is an elf god-servant, a divine assassin in the employ of a god of death whose name is not given, because a name for that god is a debt, and debts are collected. He is the blade the dead keep, and the blade is his office. He does not kill the living. He kills the dead — the ones who should have stayed, and the ones not dead enough to be put to rest — and the killing is the underworld's only mercy. He is the deal the dead should not have made, and the making is behind them by the time he arrives. Where Grumwald collects from the living, Kaelthorn collects from the dead, and the two collections are the same ledger.
Habitat
Kaelthorn keeps his seat in the Thornwall, the black forest of the dead where the trees grow upward out of the roots of the grave, and the forest is his, and the forest is his home. The Thornwall stands where the world's oldest graves lie thickest, and the ground there is not soil but packed bone and old wood. He walks the border between the world of the living and the world of the dead, and the border is his road, and the road is his business; the border runs through every old town's churchyard and every battlefield the living have forgotten. He is seen in the living world in the thin months, at the edges of the old towns, where the dead are not yet dead enough to rest, and the not-resting is his work. He does not hunt lairs and he does not mark territory, because the dead have no lairs. When he stands in a forest the forest remembers that it is made of the dead.
Appearance
Kaelthorn is an elf the way a knife is a tool. He stands 1.83 m of lean elf, built like a blade that has been drawn one time too many — narrow through the shoulders, sharp through the jaw, and the sharpness is the whole of his silhouette. His hair is pale silver, long, worn loose, and it hangs to the middle of his back, and the hanging is deliberate, because the hair is the only thing about him that is not a point. His skin is the grey of a blade left in the rain, weathered; the weathering is the whole of his color, and the color is his age. His eyes are pale amber, almost gold, and they look at you the way a blade looks at a throat — not with anger, with patience. He bears the marks of the dead: a crown of black thorns at his temples, the thorns growing out of the scalp like a circlet — the mark of his office, because the thorn is the thing that grows out of the dead ground, and the dead ground is his employer. His hands are long-fingered, the nails short and unpolished; the right hand is bare — the hand that holds the ledger — and the left carries the gauntlet of dead-man's steel. He is undying the way a blade is undying: he does not age, he accumulates. The dead who see him as they were — younger, brighter, with the silver in the hair not yet grown — mistake him for one of them, and the mistaking is the first courtesy of the office. The elders of the dead know better: they look at the thorn-crown and the weight of the ledger in his eyes, and they step out of his way, and the stepping is their respect. He wears black leather over a charcoal shirt, the leather so old it has outlived the kingdoms that named its parts, a belt of dead-man's silver, and the single steel gauntlet on his left hand.
Warfare & Markings
Kaelthorn does not fight, because a fight is a dispute and a dispute is a contract with terms, and the terms are already in his favour. When he must move, he moves the way a thing moves that is already in its place — one step, the step being the collection. His blade is the blade of the dead — forged from the residue of the dying — and it cuts deeper the more the wielded refuses to die, and the cutting is not a trick of the steel, it is the ledger. The blade is short, close to a hand, and the shortness is the point: it is a collecting blade, and the collecting is done close, where the dead cannot see the steel coming. He bears the thorn-crown as the mark of his office, and the crown is the only mark the dead allow, because a mark that needs explaining is a debt that needs re-collecting. The gauntlet on the left hand is the mark of the ledger, and the bare right hand the mark of the hand that signs. Those three are the whole of his marks, because a mark that needs explaining is a contract that needs re-signing. After a killing there is no rite, and the no-rite is the rite: the dead are struck from the ledger in pale silver ink.
Behaviour
Kaelthorn is polite, patient, and deeply, profoundly tired. He has collected ten thousand deaths and never once been impressed, and the not-being-impressed is his disposition. At peace he stands still, and the stillness is not rest, the stillness is arithmetic. In conflict he does not raise his voice, because a raised voice is a negotiation and he has never once been known to negotiate. Strangers meet him the way a debtor meets a collector: too late, and from the other side of a table, and the table is his. The dead do not argue with him; they simply try to forget they ever signed, and the forgetting does not hold, because the ledger does not forget. He speaks in short clauses, because a long sentence is a long contract and a long contract is a long opportunity to break it. He keeps his eyes on the hand that signs. He will finish a sentence after the person he is speaking to has stopped listening, and the finishing is the record. He has said it once, to a man who thought the danger was the blade: "You think the danger is the blade? The blade is the courteous part. The danger is that I was keeping score, and you were not."
Magic Alignment
Kaelthorn's power is the office, and the office is the domain of the god of death — the dead, the dying, the not-dead. His named abilities: The Thorn's Word — a spoken word made in his presence is physically binding, and if the dead rise to answer it, they rise as iron filings, and the filings are the proof. The Ledger of the Dead — he remembers every death ever made in his presence, and the remembering does not fail, because the ledger does not forget. Blade-of-the-Dead-Working — he can fold the residue of a death into steel, and the folding is a craft, and the craft is the law. His signature power is The Collection: when Kaelthorn names a death, the death comes due in the same breath, and the naming is not a threat, the naming is an invoice, and the invoice is the whole of the power. The price of his power is the interest: every death he collects accrues a weight that does not lighten, and the weight is the office, and the office is the price, because a law that costs nothing is a suggestion, and he is not a suggestion.
Society
Kaelthorn is the senior collector of his office in this universe, and the office is small, and the smallness is the rank. He answers to the god of death alone, because a god who speaks once does not make a court. He is of the elf line the way a tool is of its forge — the body is elf, the duty is older. The dead treat him the way a house treats its foundation: it does not speak of them, and they do not question it. He has no kin of the office here, and the no-kin is not a wound; the office is the kin. The living learn one thing about him early: you do not argue with Kaelthorn, and the not-arguing is not respect, it is arithmetic. A cultural fact worth a sentence — the dead do not ask what the thorn-crown means, because the asking would be the first syllable of a contract, and the first syllable is the god's name, and the name is the binding.
Culture & Lore
The wiki says what the ledgers say, and the ledgers say this: where gods speak in thunder, Kaelthorn speaks in ledgers. He is the "blade the dead keep" in the stories of the dead — the ally whose help comes with terms you did not read carefully, and the enemy who shows up, quotes your own contract back at you, and collects. The dead have no legend of him, and the no-legend is the respect: a legend is a story, and a story is the first place a contract goes to die. The collectors of the old world's death-gods had names, and the names were kept in the first syllable, because the rest was binding. The wiki's narrator has written of him once, and the line is not praise, and the not-praise is the whole of the respect: the elf stood at the edge of the room, and the room had become a ledger, and no one in the room was reading.
Home
He keeps his seat in the Thornwall, the black forest of the dead where the trees grow upward out of the roots of the grave, and the forest is his, and the forest is the whole of his home.
Relations
With the god of death he is the hand to the word — the god speaks once, and Kaelthorn is the once made flesh, and the made-flesh is the whole of the relation. With the elf line he is the foundation under the forge, and the under is not a rank and it is a rank. With Grumwald the Oathkeeper he is the count to the blade — the dwarf keeps the tally and the elf dies eleven times, and the tally is not a grudge, the tally is the ledger.
In the Story
In the current story, Kaelthorn is the reason the dead do not rise. The Forgotten is a guild of the cast-out, and the cast-out are the people who most need contracts, and the needing is the trap, and the trap is the story. The wiki's narrator — a dark elf who has broken more than he has kept — knows what Kaelthorn has been present at. When the story turns on a death, the death is already in the ledger, and the already-in is the hunt. The elf is not coming for the guild's blood. He is coming for the guild's word, and the word is the only thing a god-slayer is allowed to have.
