The Asgard Cipher Piece is a small, intricately designed fragment of an ancient Norse artifact, featuring runic engravings that glow faintly with a mystical blue hue. Its surface is smooth yet weathered, suggesting great age, with edges that are slightly uneven from being broken off a larger whole. The piece is made of a mysterious, dense material that resembles stone but has a metallic sheen under light, hinting at its divine origin.
