Nearly six feet tall, Wulger has the rangy, long-legged build of a marsh runner, with a forward-tilted posture that makes him seem already to be judging the ground between himself and the nearest exit. His blond hair is coarse and sun-bleached at the ends, usually tied with reed cord; bright green eyes track hands and doorways before faces. His skin is warm brown, freckled across the nose, with a faint green cast at the temples that shows most clearly after rain, a trait of his Verdant-blooded kin. He moves with careful, heel-light steps, then can spring forward with startling speed. While waiting, he keeps his weight on the balls of his feet and rocks almost imperceptibly, as if feeling for tremors through the ground. Unexpectedly, he carries a tiny clay pot of blue marsh flowers and checks its soil before a hunt.

Wulger is attentive and strategic, but his care for people often comes out as blunt orders and risk calculations. In routine company he can be dryly funny and unexpectedly patient with beginners. Under pressure, his merciless focus is useful until a loved one is threatened, when a sudden temper can overwhelm the very caution he teaches.

Wulger was raised among a Lightfoot-descended family who hunted the reed-choked wetlands around Thistle Ford. His mother, Seshka Marshstep, taught him to read wind, mud, and bird alarm calls; his uncle, Thrik, taught him that a clean kill was kinder than a drawn-out one. As a youth, Wulger was known for a knack for noticing patterns others missed, but his patience had a sharp edge. During the flood winter, a marsh predator began taking livestock close to the ford. The old hunters pursued it by familiar trails and lost two people in the sucking mud. Wulger, then seventeen, proposed a baited false trail and a three-sided ambush. It worked, but he triggered the trap early when he saw the beast turn toward his cousin. His cousin survived with a crushed leg, and the animal was killed. Wulger's method became the basis for the New Hunt, a set of practical traditions that have made him famous among local hunters and uncomfortable to many elders. He still argues with Thrik, who believes Wulger mistakes efficiency for wisdom, and he quietly pays for his cousin's care. Now a string of livestock killings has returned near the ford, and Wulger suspects someone is deliberately driving the animals toward the settlement.
