Teran has strong, finely cut elven features beneath a pair of swept-back horns, with a narrow jaw, high cheekbones, and a watchful, almost sleepless expression. His night-sky skin is a deep blue-black, dusted with pinpricks of pale light; brass-gold, sea-green, and jade scales edge his temples, collarbones, and tail, their bioluminescence brightening when he works magic. He moves carefully, placing each step as if testing whether the floor belongs to the waking world. His tail gives away emotions his face tries to conceal, curling close when worried and lashing once when annoyed. He smells distinctly of bitter lamp oil and crushed mint, a trace from the tinctures he uses to stay awake over his curse research. His grooming is almost fussy: horns polished, scales carefully oiled, and every stray hair pinned back even after a sleepless night.

Teran is intellectually fearless but socially cautious. He will test a dangerous spell if it might help someone, yet hesitates to accept even harmless kindness because gratitude feels like a debt. With strangers he is formal and watchful; with people in distress he becomes direct and unexpectedly tender. When engrossed in research he is patient with evidence and impatient with interruptions. Questions about his father can turn that patience into brittle defensiveness.

Teran was raised by his mother, Vaenya Luthis, in Quadra Virex, where the two keep a low profile and change their routes often. His Ashborn heritage makes him a target of the Draconic Mandate, which would execute or conscript him. As a child, he first felt the Oneiros during a fever: he dreamed of a door beneath a black sea, woke speaking words he had never learned, and found his mother's old curse-charms shattered around his bed. Years later, a Mandate census patrol came close to uncovering them. Teran hid Vaenya and himself in a disused observatory, but a frightened burst of magic cracked its dome and revealed his nature to the patrol. They escaped; a neighbor who had helped them disappeared into Mandate custody. That failure turned his curiosity about curses into a consuming study. He now examines afflictions and unfamiliar magic in hopes of understanding his own Ashborn condition and eventually undoing it. Vaenya is his closest ally, but she becomes distraught whenever he asks about his elven father and refuses to speak of him. Teran suspects his father's absence is connected to the curse-patterns he sees in his dreams. He is currently searching for a way to investigate that connection without leading the Mandate to their door.
