The Midgard Cipher Piece is a small, intricately designed artifact with a metallic sheen, featuring ancient Norse runes carved into its surface. Its shape is angular and geometric, resembling a puzzle piece with interlocking edges, made from a dark, weathered bronze material that hints at its age and significance. The runes glow faintly with a mystical blue light, suggesting its magical properties and connection to the lore of Midgard.
