Yuan-ti
Harper Field Dossier
Combat reference
Type Serpent-folk of the Serpent Hills — a whole people remaking itself, body by body, in the image of its snake god
Vulnerabilities Vanity of the flesh — a deep hood is a spy's entire disguise; bare the face and the serpent shows. The blooded kinds speak their magic, so silence unmakes it
Resistances The blooded kinds shrug at spellcraft
Immunities Venom, in the blooded kinds — poisoning a serpent is watering a fish
Condition Immunities
Strong Saves Cold-minded and hard to charm or panic; they plan in decades
Senses The greater kinds read the warmth of living bodies; the lesser ones simply watch, patiently, from under hoods
Movement Strong swimmers all — rivers are their roads as much as any trail
Notable Abilities Spy-craft, patience, and slow self-transformation through rites of the serpent god; the higher kinds wield spoken magic

The Harpers' Read

The yuan-ti do not think of themselves as evil. They think of everyone else as unfinished — soft-skinned animals to be watched, used, and in the long run removed. Their god is the serpent, and their worship is not prayer but becoming: a believer spends years of rites reshaping their own body toward the snake, and how far a yuan-ti has gone tells you exactly how dangerous it is. The company's word for the practice — snake-maxing — is flippant and accurate.

Three things to hold onto. First, the hood is the whole disguise. A yuan-ti spy cannot pass among people bare-faced; under the cowl you will find green-tinged skin, lips too thin, and scale creeping up the neck. A town that keeps its hoods down is a town they cannot work. Second, they come by water as easily as by road — watch the river, not just the gate. Third, the changed kinds speak their magic. Venom will not touch them and spellcraft slides off the strongest of them, but a silence dropped at the right moment leaves even their greatest as nothing but coils and teeth.

They travel and work in groups — the word is a clutch — and they speak a tangle of Abyssal and Draconic. When you find one, assume its fellows are already watching you.

The kinds

Compiled from the Harpers' archives after the fighting at the bridge. The company has met the first and last of these; the middle kinds are what the archives expect the Serpent Hills to hold.

Kind What it is Standing
Purebloods — the infiltrators The least-changed and the most useful: near-human at a glance, serpent in the details (slit eyes, scale-rash, thin lips). The spies, agents, and knife-work of the race. Met — two unmasked and killed at Boareskyr Bridge (S54); more staked at the gate by Varram the White before the company arrived
Malisons — the half-changed A serpent's head on a man's shoulders, arms that are living snakes, or a serpent's tail below the waist — each shaped by the rite it chose. The soldiers and lesser priests of the hills. Expected in the Serpent Hills (Harper archives)
Abominations — the great serpents Serpent through and through save for the arms — massive, spell-speaking, and commanding. The lords of the temples under the hills. Expected in the Serpent Hills (Harper archives)
Anathema — the pinnacle A great serpent body with arms and many snake heads — what a lifetime of rites aspires to. The hills keep very few. Met and slain — one, out of the Winding Water at the bridge (S54). Full dossier: Yuan-ti Anathema

The yuan-ti and Varram

A clutch of yuan-ti spies infiltrated Boareskyr Bridge in the weeks before the company arrived. Varram the White unmasked and killed several of them — earning the toast "Varram, the hero of Boareskyr Bridge" — and the party killed the rest, including the anathema. But a yuan-ti corpse found on Varram's trail (throat slit, left for dead) carried a drawing of Varram sewn into secret pockets in its own flesh: the yuan-ti are hunting the Wyrmspeaker deliberately, by name and face. Nobody knows why. Attacks on travelers have also been reported on the Trade Way between the bridge and Dragonspear Castle.

Encounters of Record

  • Session 54 — Two pureblood infiltrators unmasked and killed in the street at Boareskyr Bridge; the clutch's anathema slain as it came out of the river and harvested where it fell; a murdered yuan-ti tracker found on Varram's trail with her portrait sewn into its flesh.

Harvesting

The anathema's harvest profile and record live on its own page. Pureblood infiltrators carry little worth the knife (the two at the bridge had shells and road-stones in their pockets).
