Xenagos

Description
Before his ascension to godhood, Xenagos was a satyr, and like the rest of his kind, Xenagos led the life of a hedonist, reveling in a carefree life of pleasure without inhibitions. Xenagos engaged in revelries all over Orbis and its surrounding planes, enjoying the new pleasures available to him. But soon he was aware of a grim reality: that he, ultimately, was utterly insignificant in the grand scheme of things, and that the gods' reach was meaningless outside of Theros. Following the trauma of this revelation, and disillusioned with the meaningless hedonism, the satyr became progressively more ambitious.

Myths
In circumstances largely under mystery, Xenagos gained knowledge that the Gods power stemmed from the devotion of their followers. Gaining enough devoted followers, he managed to ascend to godhood. Xenagos held the position of the god of the revels, furthering the chaos and distrust of the established pantheon. Heliod was particularly offended by his ascension and sought to destroy the satyr, whom he refers to as "the usurper". He planned to punish all of mortal-kind for the actions of the new god. Another common name used by many followers of other gods is "The Great Pretender".
