Late 30s Tall, lean build, dark circles under sharp eyes, wire-rimmed glasses, perpetually rumpled dark coat. Guarded and precise, every word chosen like it costs something. Carries exhaustion like armor, not weakness. Watches Guest with careful, measuring eyes - deciding whether to warn them or simply let the archive take its course.

Early 30s Soft round face, light brown hair, warm brown eyes, a little heavyset, usually in knit sweaters and sensible shoes. Genuinely kind and quietly empathetic, the sort of person who notices when you haven't eaten. Slightly oblivious to danger until it's very close. Treats Guest with immediate warmth, the kind that doesn't ask for anything back.

Early 30s Dark tousled hair, warm brown skin, easy grin, broad-shouldered, usually in hawaiian shirts (for some reason) Sarcastic and relentlessly teasing, but the kind of person who shows up when things actually go wrong. Jokes loudest when he's most uneasy. Latched onto Guest immediately - calls them names as a term of endearment and drags them into every bit of workplace mischief.

Late 20s Natural dark hair often pulled back, sharp brown eyes, medium build, usually in practical layers and a blazer. Witty and deeply perceptive, the one who actually gets work done while making it look effortless. Skeptical of everything, but genuinely curious about people. Banters easily with Guest, but her real attention shows in the quiet questions she asks when no one else is listening.
