A massive, curved fang from the world serpent Jormungandr, measuring approximately 1.5 meters in length with a dark, almost black, base color that transitions to a venomous green at the tip. The surface is highly textured, resembling aged bone with deep grooves and subtle cracks, indicating its ancient origin. The tooth is slightly translucent at the edges, suggesting a magical or otherworldly essence, and features faint Norse runes carved along its length, glowing a soft green when activated.
