You see Sevynne the Disciple of Althedeus.
She appears to be a Half-Elf.
She is taller than average and appears to have come of age. She has crimson-veined luminescent yellow eyes and dark-splotched bronze skin. She has long, wavy dark burgundy hair left unbound save a few slender, beaded braids that drape over her shoulders. She has a rot-damaged face and the left side is little more than bare bone and tendons. Portions of the flesh of her legs, arms, and hands have been stripped away to leave only bone and wisps of shadow.
She is in good shape.
She is wearing a deeply hooded grey muslin robe with a ragged hem, linen bandages from head to toe that spiral along her limbs and body to her neck and are stained in shades of ruddy brown and yellow, and a pair of leather-tied sandals.
Sevynne was sent to Wehnimer's Landing by the shadowy demon Althedeus, where she plagued many, tortured them, and even collected blood and performed rituals for her dark master. She also worked to help recruit others to her side, but in time she was defeated and the shadowy remnants of her bones were infact harvested and used by Pylasar and Aralyte to create shadowbane weapons that eventually led to the weakening, and unraveling of Althedeus.
