Asgardian Steel is a high-quality, semi-realistic metal with a dark, almost black base color, infused with subtle glowing blue runes that pulse faintly, indicating its divine origin. The surface is smooth yet bears fine, intricate engravings of Norse patterns, suggesting its craftsmanship by the gods. The edges are razor-sharp, reflecting light with a cold, metallic sheen, and the material itself is slightly translucent at the thinner sections, revealing the inner glow of the runes.
