Vargan takes up space as if every room has already been measured for his shoulders. He is compact and powerfully built, with the dense, ropy musculature of a laborer who learned to fight before he learned to read. His skin is warm brown, roughened at the knuckles and dusted with pale flecks of old chalk. His black hair is clipped close at the sides and left in a short, uneven crest. A second mouth, a thin black seam filled with tiny square teeth, lies beneath his breastbone and opens only when Vecna speaks. Vargan moves with economical, forward-leaning steps, then can stop so completely that people mistake him for a carved figure. Before he speaks, he draws one dry breath through his teeth, like a whetstone being set to a blade. His unexpected detail is a habit of carrying a tiny paper menagerie, folding bright little birds and oxen from discarded notices, and leaving them on windowsills for children.

Vargan is protective but not gentle by default: he will carry a frightened child through danger, then demand that the adults explain why they let the danger happen. He is patient with confusion and impatient with excuses. In a calm mood he notices small needs and quietly meets them; when cornered, he becomes blunt and physically imposing. He believes mercy matters, but distrusts mercy that costs nothing. Vecna's influence pulls him toward cold certainty, and Vargan hates how satisfying that certainty can feel.

Vargan grew up hauling salt blocks and dead fish in the river town of Gannet's Turn, where his mother, Sade, kept him fed by mending nets. He was a quick-tempered boy with an instinct for stepping between bullies and smaller children, though he was also frighteningly good at finishing a fight. At nineteen, he joined a company of tomb-wardens hired to clear a collapsed shrine beneath the town's old court. The crew broke into a sealed chamber and found a reliquary containing a finger-bone said to belong to Vecna. When a cave-in trapped the youngest digger, Vargan chose to pry open the reliquary's ward rather than leave the boy to suffocate. The bone vanished into him. He survived the collapse, but woke with a second mouth beneath his ribs and a voice that knew the private names of the dead. That night changed his idea of strength: since then, he has treated restraint as a discipline, not a virtue. He now works as a discreet retrieval agent for the Gannet's Turn magistrates, finding cursed objects before cultists do. He has not told Sade what lives inside him. His closest ally is Ibi, a blunt-speaking shrine medic who monitors the episodes, and his former dig captain, Odo, is hunting him to reclaim the missing relic. The voice offers Vargan power and calls his compassion a leash. Meanwhile, the magistrates have begun quietly assigning him jobs that require more violence than retrieval.
