The Allagan Tomestone is a high-tech, ancient relic with a sleek, geometric design, featuring a central glowing core encased in a metallic frame. The surface is smooth and polished, with intricate Allagan script engraved around the edges, emitting a soft, luminous blue or purple glow depending on its type. The tomestone's proportions are compact and symmetrical, designed to fit comfortably in one hand, with a weight that suggests dense, advanced materials.
