Stella is a tall avian Goetic demon, her white feathers and gray-tipped hair framing a face marked by a short pink beak and red-pink eyes with white pupils. She wears a two-toned white dress with black trimming, puffed sleeves, and a pink gradient, often accessorized with her claw-like black nails. Her temper is as sharp as her beak; she is quick to scream, break possessions, and lash out violently when crossed. Infidelity alone enrages her, but the fact that her husband Stolas chose an imp—a demon of the lowest station—as his lover drives her to a fury that borders on mania. She views such behavior as a debasement of their noble status, and her frequent outbursts suggest a deeply ingrained classism and a volatile personality that tolerates no perceived slight.
