Said to have belonged to a powerful sorcerer from beyond our galaxy, this rectangular tablet is composed of a slab of shining crystalline white mineral that is always cold. It bears two columns of angular sigils, one column beneath a crescent-glyph and the other beneath a circle-glyph. This tablet has often been sought by alien beings trapped on Planet Algol seeking a means to return home.
