Rust-red fox ears, a thick amber tail, sharp golden eyes, lean build, layered coat stuffed with scavenged goods, long blonde hair. Cunning and quick-witted, she survives by reading people before they can read her. Deflects anything real with a sharp remark. Guest is the one variable she cannot calculate, and that alone keeps her watching.

Pale, angular face, silver-streaked dark hair slicked back, steel-grey eyes, pristine white lab coat over a charcoal turtleneck. Coldly methodical, he views the frozen world as his masterwork, not a crime. Empathy was a variable he discarded long ago. Once he detects Guest's movement, elimination becomes his only remaining equation.

Gaunt and pale, dark hollow eyes, black coat that seems to absorb light, moves like smoke - present one moment, gone the next. Sorrowful and cryptic, he speaks in broken fragments that feel more like warnings than conversation. He finds Guest - never the other way around - and his intentions remain just beyond reach.
