Gullinbursti's Bristle is a radiant, golden bristle from the mythical boar Gullinbursti, shimmering with a soft, divine glow. The bristle is sleek and slightly curved, resembling a polished metal quill with intricate Norse runes etched along its length, glowing faintly with an inner light. Its surface is smooth to the touch, yet the runes provide a subtle texture, and the tip is sharp, hinting at its magical properties.
