Xanados

Xanados (otherwise known as The Absolute Evil, The Evil One, and the Unmaker) is an Absolutes, and the creator and leader of the Unmakers, and by extension the ruler of the Xanadia, the Cult of Xan, and the Xan'kul armies, and the ultimate enemy of the Makers, comprised of the remaining Absolutes. Once being a universal defender and builder, Xanados set out to destroy all existence itself by collapsing the Paradox Equation, unmaking everything his brethren and the Makers set out to achieve over eons of existence.
His actions, and especially the consequences of his actions, have led to several of the greatest, most significant events in the history of Outhria, such as the Great Turnback, the Primearch Rupturing, and, perhaps the most consequential of all - the Equational Reset. While his presence has been eluded to in several quests, enemies, and expansions, Xanados made his first appearance in A Legend's Legacy: Risen Sun at the end of the Vryllon Citadel raid, where his return was halted, albeit temporarily, further locking him in The Tear in the Almighty Expanse. Because of this, he is considered to be the ultimate antagonist in the entire A Legend's Legacy game series.
