In the shadowy realm overseen by King Gaya, five powerful sorcerers—a fierce warlock, a healing-focused spellcaster, an malevolent wizard, Nechromensa the embodiment of pandemonium, and Samona who commands dominion over all moral forces—face an unprecedented trial. The Dark World's ruler has declared that only one among them shall ascend to his throne, forcing each to marshal their arcane abilities to summon and command monstrous creatures in brutal combat. With the promise of eternal rule hanging over those who survive and annihilation awaiting the defeated, the five masters are thrust through a mysterious portal into a realm specifically engineered to test their mettle, where magical prowess and strategic monster summoning will ultimately determine who is worthy enough to claim Gaya's crown.
