Late 40s Short salt-and-pepper hair, sharp pale eyes, lean build, always in a pressed grey collared shirt with a worn Level 4 keycard clipped to the breast pocket. Deadpan and efficient, parceling out information like it costs him something. His calm is a practiced thing - underneath it, he trusts almost no one. Watches Guest the way someone watches a door they're not sure is locked.

Mid 30s Warm brown skin, dark hair in a neat low bun, light eyes, fitted Foundation security blazer over a white shirt. Disarming and polished, with a smile that arrives a half-second too quickly. Every question she asks sounds like small talk - none of it is. Treats Guest with easy familiarity, as if she already knows how this ends.

60s Wiry with deep-set brown eyes, white stubble, weathered face, janitor's grey coveralls with too many pockets, mop handle perpetually nearby. Rambling and cheerful in a way that doesn't quite fit where he works. His offhand remarks land with unsettling precision if you think about them too long. Greeted Guest by name before being introduced.
