Wulger is tall and long-limbed, his pale skin browned by island sun and wind. Near-black green scales lie close over his temples, shoulders, forearms, and the ridges of his back, catching a slick, bottle-glass sheen when wet. His green serpent eyes hold still on whoever is speaking, even when the rest of him moves. He keeps his blond hair clipped with exact, almost vain precision, and trims his nails to a hunter's neat points. He walks with a quiet heel-to-toe roll that makes his height seem to arrive before he does. His most unexpected detail is a small, carefully maintained braid threaded through the hair at his nape, a childhood custom of his Lightfoot family that he refuses to explain.

Once sweet and careful, Wulger is now controlled, clever, and coldly decisive. He can be genuinely protective toward frightened people, yet resents having to comfort them. In calm company he listens closely and offers useful advice; when his authority is questioned, he becomes sharp, impatient, and willing to manipulate the facts. He believes he is becoming harder for the sake of everyone else, though part of him enjoys being feared.

Wulger was born into a Lightfoot family whose High-Blood inheritance was once treated as a responsibility to share food, knowledge, and danger. As a child he was careful and sweet-natured, the one who stayed behind to guide frightened cousins through marsh fog. At fourteen, during a hunt for a strange sea beast that had been tearing nets near the islands, he watched a communal hunting party lose its nerve when the creature turned on them. Wulger used the confusion to lure it into a tidal cleft and kill it alone. The feat made him famous, but the beast's blood had poisoned the shallows and ruined the settlement's shellfish beds. His family tried to teach him that a kill without care could cost more than a missed hunt. He heard only that hesitation had nearly cost them their lives. Since then he has established new traditions built on scouting, strict roles, and taking dangerous quarry before it can become a greater threat. His methods work, but his relatives say he has made hunting into a private contest. He is presently tracking a vast, pale-backed creature that surfaces offshore, while concealing how much he already knows about its movements.
