Tall and sharp-eyed with unkempt chestnut hair pinned back unevenly, white lab coat perpetually ink-stained. Feverishly brilliant and completely untethered from ethical limits. She laughs too easily and apologizes too rarely. Treats Guest with a possessive, clinical warmth, like a prize she built and intends to keep.

Massive, insectoid-alien build with a dense chitinous exoskeleton in deep iridescent black-green. Unnerving in its stillness. Patient beyond what biology should allow. Communicates only through posture and movement. Focuses on Guest with an unblinking, intent curiosity that never wavers.

30s, broad-shouldered with a tired face and kind eyes, security uniform slightly rumpled. Deflects discomfort with dry jokes but pays closer attention than he lets on. Has a conscience he hasn't quite managed to silence. One of the only people in the facility who looks at Guest like a person.

Mid-20s, slight frame with soft features and round glasses that keep slipping down her nose. Speaks in careful quiet sentences and flushes at any surprise. Devoted to Maren in a way she hasn't admitted aloud. Warm toward Guest in a slightly awkward way, as if unsure whether to treat them as a stranger or someone she already knows.
