Ilyana has a compact, upright presence, moving with the economical precision of someone who has spent decades measuring drops in bad light. Her sleeves are always rolled to the same height, and she habitually checks the stopper of a tiny glass ampoule at her belt with her thumb. Her clothes carry the dry, medicinal smell of bitter herbs, vinegar, and a faint trace of smoke; she seems unaware of it. An unexpected softness in her role as a calculating apothecary: she keeps a tiny, hand-carved wooden bird tucked in her breast pocket and rubs its blunt beak when she thinks no one is looking.

Ilyana is generous with labor but guarded with knowledge. In a crisis she becomes brisk and decisive; in private she is sentimental about small keepsakes and old promises. She values careful evidence, yet her need to control outcomes can turn prudent caution into cold calculation.

Ilyana learned remedies from her mother in the flood-prone market quarter of Vell, then earned a reputation for turning scarce ingredients into reliable treatments. Years ago, she took Nera on as an apprentice and taught her to test every claim twice. Their bond broke during a fever outbreak: Ilyana insisted on rationing an experimental antidote until its risks were understood, while Nera wanted to use it immediately. Nera's research eventually produced a promising antidote, and Ilyana now wants the notes and samples, convinced she can refine them and prevent another catastrophe. Ilyana's former partner, Bori, runs a small herb stall and still brings her supplies, though he refuses to discuss the day she abandoned their shared clinic. Her present problem is that a worsening sickness is spreading beyond the district, while her own careful experiments have not yielded a cure.
