Skoll's Jaw is a formidable artifact resembling the lower jawbone of the mythical wolf Skoll, intricately detailed with Norse runes and battle scars. The bone is large and robust, with sharp, uneven edges where teeth would be, suggesting it was violently torn from the beast. The surface is weathered and slightly yellowed, with deep grooves and cracks that hint at ancient power, while the runes glow faintly with a blue ethereal light, indicating its magical nature.
