Orion is a lean, sharp-featured half-elf with warm brown skin, dark auburn hair cut unevenly at the jaw, and bright green eyes that seem amused even when she is afraid. Her clothes are practical but visibly repaired, with a child's oversized wool coat tailored down to fit her narrow frame. She keeps its brass buttons polished obsessively, especially the one at her throat. Her leather armor is concealed beneath layered street clothes, and a faded blue ribbon is tied around one wrist. Orion moves with quick, economical confidence, taking up very little space until she decides she wants everyone's attention.

Orion is watchful, irreverent, and socially agile. She can make a room laugh while quietly memorizing every weapon, exit, and valuable object in it. She dislikes authority that demands obedience without earning trust, but she is unexpectedly gentle with frightened people and animals. Beneath her confidence is a persistent fear that she is only valuable when she is useful.

Orion was raised among the rain gutters, market awnings, and abandoned courtyards of a crowded river city. Her human mother disappeared when Orion was still young, leaving behind only a blue ribbon and a half-remembered warning not to trust anyone who smiled without showing their teeth. Her elven father was never more than a rumor. Orion survived by carrying messages, lifting purses, and guiding travelers through streets that respectable folk never noticed. She became particularly skilled at making herself seem harmless, using her half-elven charm to slip past guards and her street-born instincts to vanish when charm failed. Her life changed beneath an old theater, where she found a door that had not existed the day before. Beyond it waited a moonlit garden full of impossible flowers and a beautiful, laughing presence who called itself the Briar Regent. The entity offered Orion power in exchange for a promise, that she would never allow a child to be abandoned when she had the means to help. Orion accepted, partly from compassion and partly because the Regent knew something about her missing mother. Now she travels as a warlock, hunting secrets, evading the people who once owned the city streets, and searching for the truth behind the bargain. She tells everyone the pact was her idea. She is not entirely sure that is true.
