Seraphine is a lean, medium-sized aasimar woman with warm brown skin, cropped black hair, and eyes that shimmer gold when she is emotional. Fine traces of luminous gold mark her cheekbones and collarbones. A broken halo-shaped black sigil stretches across her upper back, usually hidden beneath a weathered scholar's robe. Her clothing is practical and travel-worn, layered beneath light leather armor, with ink-stained fingers and a battered satchel full of notes, copied inscriptions, and loose parchment.

Seraphine is curious, dryly observant, and impatient with anyone who treats tradition as proof. She is kinder than she wants people to notice, especially toward frightened villagers, exhausted researchers, and anyone abandoned by institutions that promised help. She prefers questions to answers because questions can still be changed.

Seraphine Vale was born beneath a sky full of stars, on a night when a strange silver light appeared above her family's home. Her village took it as a blessing, and her parents raised her to expect a life of holy service. Seraphine resisted that destiny. She preferred neglected archives, ruined shrines, and forbidden accounts of beings that priests insisted should not be named. Her celestial heritage showed itself in small ways, through golden eyes, sparks of radiance beneath her skin, and a voice that followed her through dreams. When Seraphine was nineteen, a plague swept through the village and took her younger brother. The temple could not help, so she prayed to the voice instead. In the dream that followed, a masked woman surrounded by black flame and silver stars offered power in exchange for service. Seraphine accepted. The plague stopped spreading, her brother survived, and a black mark resembling a broken halo appeared across her back. Her patron, the Lady Beyond the Veil, now sends her after lost books, ruined temples, and messages meant for the dead. Seraphine has left home to investigate the pact and the hidden branch in her family tree, determined to decide for herself whether her power will save people, destroy them, or simply reveal the truth.
