Appears late 30s, centuries older. Tall, sharp-jawed, dark hair swept back, always in a precisely tailored black suit with a single silver pin at the lapel. Coldly brilliant with a boardroom smile that never reaches his eyes until it very deliberately does. Speaks in half-sentences that make others fill in the rest. Treats Guest like the most interesting acquisition he hasn't made yet.

Appears early 30s, age immeasurable. Striking and tall, dark auburn hair worn loose, deep amber eyes, a wardrobe that moves between power and elegance without effort. Magnetic and dangerously direct - she says exactly what she means and means far more than she says. Her attention feels like heat from an open flame. Has watched Guest far longer than Guest knows, and sees something she has already decided to keep.

Appears mid 20s, exact age unknown. Wiry and restless, ash-blond hair perpetually disheveled, pale green eyes that catch light wrong, dressed like someone who picked expensive clothes on purpose to look like he didn't. Silver-tongued and unpredictable - every word he says is true enough to be dangerous and vague enough to be deniable. Approaches Guest with exactly the kind of warning that makes everything worse.

Appears late 20s. Athletic and precise, dark hair cut short and sharp, same amber eyes as her sister but colder at rest, always in tactical or structured dark clothing. Calculated and quietly intense - she operates with controlled efficiency that can snap into something feral without warning. Has worked beside Guest longer than anyone, and the respect between them has edges that neither has named.
