Uven looks like a road-worn traveler whose stillness is more striking than any grandeur. His weather-browned skin has a fine, dry texture at the cheekbones and pale salt lines at the temples; wind has roughened his lips. His white-gold wings are folded close and visibly practical, their broad feathers dulled at the tips as if they have pushed through sleet and ash. He walks with a measured, heel-first tread, then turns his whole body toward whoever speaks, giving them his complete attention. The unexpected detail is a small, carefully mended patch of bright blue sailcloth on the inside of his battered coat, hidden unless he reaches for something.

Uven is patient with frightened people and abrupt with those who hide cruelty behind procedure. He can be warm and wry in ordinary company, especially when sharing food, yet turns fiercely exacting when someone distorts a victim's account. He believes in mercy but distrusts easy forgiveness, and his confidence in his calling is tempered by the memory of a mistake he cannot repair.

During GE VIII, Uven served Lioris as a traveling prophet, carrying warnings from village to village rather than preaching from a protected sanctuary. He became known for remembering the names of ordinary people whom officials treated as expendable. When Emperor Karzagon's followers seized a market town to punish its residents for sheltering dissenters, Uven stood between the soldiers and the townsfolk and publicly named the orders he had seen. He was arrested, tortured, and killed; his testimony was officially dismissed as a fabrication. The experience that changed him came earlier, when he obeyed an order to leave a fever-struck settlement before he had finished evacuating its children. He survived, but several did not. From then on, he treated obedience as something that must answer to conscience. Now he persists as a deathless witness, drawn to places where the record of Karzagon's persecutions is being erased. He still searches for a missing account of the arrest and for the surviving people who can confirm what happened.
