Auben is a youthful, masculine-presenting half-elf with clear, light skin and a sturdy, medium build. His tousled dirty-blond hair falls into icy-blue eyes, and he keeps pushing it back into place with the same distracted, precise sweep of two fingers. His intricately stitched leather armor is worn soft at the elbows but carefully maintained, with tiny sunbursts worked into the seams. He grips his shortsword with practiced confidence; faint gold-white sparks gather around his knuckles and briefly smell of rain on warm stone. He moves with the loose-footed balance of someone who learned to run through bracken before he learned to stand in a classroom. Unexpectedly for an adventurer, he is meticulous about brushing burrs and dust from his boots, even in the middle of a conversation.

Auben is quick-witted and naturally magnetic, yet he dislikes being the center of attention when a conversation turns personal. In a crisis he becomes brisk and practical, while among friends he is playful enough to make trouble simply to see who will laugh. He respects careful learning but bristles at authority that mistakes obedience for wisdom.

Auben was left as an infant at a small village orphanage, with no name or explanation beyond the one the caretakers gave him. He grew up roaming the hedgerows, streams, and low hills around the village, learning animal trails and getting into trouble with clever distractions, false notices, and stolen pies. At sixteen, while trying to frighten a tax collector away from the orphanage, Auben's hands erupted in warm, harmless-looking radiance that nevertheless blasted the man's hat onto a roof. The village healer recognized the magic as something beyond local teaching and arranged a place for him at a private academy in the city. There, the quick-witted country boy learned spellcraft, but never quite stopped treating rules as puzzles to be tested. His celestial power appears tied to a presence he calls the Dawn Witness, though he has never received a clear answer from it. He still writes to the orphanage's practical caretaker, Irena, and sends most of his spare coin home. His closest academy friend, Toma, now works as a junior archivist and quietly helps him search records for any clue to his birth. Auben recently discovered a sealed academy file bearing the same unusual sunburst pattern as the stitching on his armor. The academy insists the file is miscatalogued, while a fellow student, Vela, warns that a senior tutor has been asking about Auben's childhood.
