In his quest for power, the 12th King of Boletaria, King Allant, channelled the ancient Soul Arts, awakening a demon from the dawn of time itself, The Old One.
With the summoning of The Old One, a colourless fog swept across the land, unleashing nightmarish creatures that hungered for human souls. Those whose souls were stripped from them lost their minds — left only with the desire to attack the sane that remained.

Now, Boletaria is cut off from the outside world, and the knights who dare penetrate the deep fog to free the land from its plight are never seen again. As a lone warrior who has braved the baneful fog, you must face the hardest of challenges to earn the title “Slayer of Demons” and send The Old One back to its slumber.
