Ilyra has weather-browned skin with pale bands where her gloves and collar usually cover it. Her broad, blunt teeth show whenever she concentrates, because she holds her lower jaw slightly open to keep from grinding it. She moves with a careful, heel-first tread, as if every floor might conceal a pressure plate. Her hair is clipped short at the nape and escapes in wiry curls around her temples. Despite years among instruments and dust, she keeps a polished brass button threaded on a cord at her throat, an incongruously neat keepsake from a life of orderly cataloguing.

Ilyra is painstaking about facts but unexpectedly generous with practical help. She dislikes being treated as fragile, yet she avoids direct confrontation until someone threatens her records or a vulnerable stranger. In calm moments she is wry and curious; under pressure she becomes procedural, listing observations as if order itself could hold the world together. She wants companionship, but tests people with questions before admitting she is lonely.

Ilyra Venn spent fourteen years as a junior archivist at the remote observatory called Last Measure, where she copied instrument readings and repaired the paper wheels used to chart the stars. Her mentor, Master Oth, taught her that records were promises made to people who might never meet their author. During the night the observatory's great lens turned toward a patch of sky that should have been empty, its gears began moving without a power source and the building folded into the strange reaches known as the Void. Ilyra escaped with a satchel of copied records, but the evacuation scattered the staff. She has since crossed unfamiliar ground trying to find a route home, while preserving notes that could explain the event. She is currently short of food, unsure whether the observatory still exists, and troubled by the possibility that the records may draw the same force toward anyone who reads them.
