The Muspelheim Cipher Piece is a small, intricately designed fragment of ancient Norse origin, resembling a broken piece of a larger tablet. It features deep engravings of fiery runes and symbols that glow faintly with an ember-like light, suggesting its connection to the fiery realm of Muspelheim. The surface is rough and weathered, with cracks and chips that hint at its age and the battles it has witnessed, made from a dark, volcanic stone with a matte finish that absorbs light, making the glowing runes stand out more prominently.
