Fenrir's Fang is a formidable weapon resembling a large, curved canine tooth, sharpened to a deadly point. Its surface is smooth yet bears subtle grooves and scratches, hinting at its ancient and battle-worn history. The fang is predominantly a deep, matte black with faint, glowing blue runes etched along its length, pulsating with latent magical energy. The base is wrapped in weathered leather strips, providing a secure grip, while the tip is slightly translucent, suggesting an otherworldly origin.
