Deep beneath the cracked ground of the Burning Lands, under the lowest caves of the Serpentines lies a magical stone chamber that has sat undisturbed for many thousands of years. The stones that make the walls of this chamber are living; they are the Vuto-duum, ancient refugees from a distant destroyed planet. They have hidden here in the rocks since the lifeless times, infusing them with a special type of magic that emits a faint violet fog. A cave-in at the Dwarven mines above recently opened a thin passage all the way to the Great Lava Lake at 1200 fathoms below the surface, and the magic escaped.
A small wisp of the violet fog eventually found its way to the Lava Lake and dived in. With complete control over the molten rock, The Vuto-duum were able to finally craft the perfect stone body for their ultimate warrior. Caladuum is infused with all the ancient wisdom and knowledge of the Vuto-duum, as well as their magical powers. He is destined to free them forever from their prison of stone, and the Splinterlands shall know a new champion.
