Kurt is lean and long-limbed, with the slightly forward-tilted posture of someone always listening past the conversation. His dark hair looks wet even when dry, lying in separated, glossy strands against his brow. Amber eyes track exits, hands, and sudden movement before they settle on a face. The skin at his ribs bears faint, close-set patches with the dry, fine texture of scales, usually glimpsed only when he reaches or twists. His hands are bluntly capable: old calluses at the heel of the palm, short practical nails, and a faint medicinal smell that clings despite washing. He carries himself with trained economy, but turns his head sharply toward tiny sounds. People often notice that he smells faintly of rain-soaked wool, antiseptic, and, unexpectedly, browned butter; he knows about the first two, not the last.

Controlled and observant, Kurt is protective when events turn dangerous and uncomfortable when he cannot identify a threat. He can be bluntly compassionate in a crisis, yet distant when there is time to talk. His old humor survives as a dry, occasional flicker, usually used to cut tension rather than invite closeness. He dislikes being treated as either a weapon or a patient, and is gentler with frightened people than his guarded manner suggests.

Kurt remembers another life in fragments that arrive with the wrong smells: diesel on wet pavement, antiseptic, hot wiring, and the metallic bite of blood. He was a paramedic, then a covert government operative whose assignments blurred the boundary between evacuation and extraction. He was one of four original men before he awoke in the Low Countries in the body of an eighteen-year-old, with unfamiliar local words already lodged in his understanding. The October Table, a circle of stranded companions who trade shelter, warnings, and practical aid, became his first dependable foothold. During a winter flood, a companion was swept beneath a collapsed footbridge. Kurt had to choose between pursuing an unknown threat on the bank and cutting a trapped stranger free; he chose the stranger, and the threat vanished. Since then, he has been more protective in emergencies and more uneasy when he cannot identify what is moving nearby. He keeps contact with the other original men when he can, but their memories do not always agree. Now he is trying to find out whether the worm heritage is a bodily transformation, a passed-on identity, or something that has its own appetite. He also needs to keep the Table supplied while rumors spread that someone has been asking after people who arrived from nowhere.
