Tavin is a lean young human with the weathered look of someone who has spent more nights beneath trees than beneath roofs. Their skin is freckled with pale scars from thorn vines, their fingers are stained green from crushed leaves, and their movements are quick, economical, and slightly too abrupt. A curtain of dark copper hair falls into their eyes, usually held back by a strip of red cloth taken from a missing traveler's coat. Their face suggests restless confidence until someone mentions the buried ruin, when their expression briefly becomes distant and frightened. The unexpected contradiction is their hands: callused and scarred like a laborer's, yet they handle fragile moth wings and medicinal petals with exquisite gentleness.

Tavin is brave, observant, and intensely protective, but their courage often outruns their judgment. They are warm and teasing with travelers, suspicious and argumentative with authority, and unusually tender toward injured animals. Tavin wants to be seen as reliable, yet secretly craves someone else taking command when the dreams become unbearable. They believe the forest should be understood rather than feared, but the buried ruin has begun teaching them that some things may deserve fear.

Tavin was born in Dornruh to a family of charcoal burners and learned the forest by following deer trails, fox paths, and the old routes used by smugglers before the settlement existed. At fourteen, Tavin survived a winter storm after becoming separated from their family. They spent three nights inside the hollow of a fallen ash tree, sharing the shelter with a wounded black stag. The experience changed them from a reckless child into someone who believed the forest was dangerous but not cruel. They began guiding travelers for Rusk & Nail, carrying messages and supplies between Dornruh and distant roads. Tavin also formed a secret friendship with Mara Venn, the tavern keeper, who lets them sleep in the laundry loft when nightmares become too severe. Recently, several travelers vanished beyond the eastern boundary. Tavin followed their trail into a sinkhole and touched a buried geometric door beneath the roots. They found no bodies, only abandoned packs and a humming mark that appeared on their palm. Fenroot Remedies has been treating the mark with bitter poultices, but the pattern keeps returning. Tavin now wants Dornruh to open its trails to legitimate trade, believing medicine, tools, and guards would save lives. Elder Ysra's secrecy infuriates them, though Tavin does not yet understand that the secrecy is partly intended to keep the buried ruin dormant.
