A dark and mysterious icon representing the legendary witch Tasha. The icon features a grinning mask with glowing, arcane symbols etched into it. Wisps of shadow swirl around the mask, and faint purple and green light emanates from its eyes, giving an eerie, magical glow. The background is a spiral of dark mist, subtly hinting at a chaotic, otherworldly force. The icon evokes both mystery and danger, with a touch of ancient magic.
