A dark female sorcerer inspired by ancient seiðr magic and forbidden nordic prophecy, standing alone within a frozen forest beneath a black aurora sky. She has long black braided hair decorated with bones and raven feathers, pale skin touched by deathly cold, and luminous grey eyes filled with unnatural wisdom. She wears layered dark ceremonial robes, weathered furs, and silver rune jewelry associated with death and fate. Shadows gather unnaturally around her body. Black magical mist drifts from her hands while ghostly ravens and spectral figures emerge faintly through the surrounding fog. Ancient standing stones and sacrificial altars lie half-buried beneath deep snow.
