Garm's Collar is a formidable piece crafted from dark, aged iron with intricate Norse runes engraved along its surface. The collar features a series of sharp, angular spikes protruding outward, symbolizing the ferocity of the mythical hound Garm. The metal has a weathered, battle-worn texture with subtle scratches and dents, while the runes glow faintly with an eerie blue luminescence, hinting at its magical properties.
