A dark female druid inspired by norse seiðr magic and ancient death rituals, standing within a frozen marshland filled with rotting trees and drifting spirits. She has long black hair decorated with bones and raven feathers, pale skin marked by ritual scars, and unsettling grey eyes filled with forbidden wisdom. She wears layered decayed furs, moss-covered cloaks, and dark ceremonial robes stitched with faded runes. Strange fungal growths spread slowly across her staff and clothing. Green ghostly spores drift through the cold fog around her while ravens gather among dead trees and broken standing stones. The atmosphere feels ancient, eerie, and deeply supernatural.
