Xenagos's History
Xenagos was a former planeswalker and shortlived God of Revels on Theros.
In circumstances largely under mystery, he gained knowledge that the Gods power stemmed from the devotion of their followers. Gaining enough devoted followers, he managed to ascend to godhood. This occurred during a minotaur siege at Akros, battled off by the armies led by
Elspeth. The victory celebration was the final ingredient to Xenagos' divine ascension, and in the ensuing turmoil, the Sun god's champion was ironically scapegoated for this, resulting in her exile to the wilderness. 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.
Xenagos had accomplished what he had desired: obtaining a place in the pantheon. However, he could not sustain his godly form by himself; he gathered a large array of Nyxborn creatures, using them to keep his position. Capturing the Nyxborn caused Theros's sky to darken, as chaos spread across the plane. His stay in Nyx would not be a long one, though. Only a couple of days after his rise, Elspeth and her friend
Ajani arrived in Nyx to set Theros right again. After a difficult battle, Xenagos managed to knock Elspeth down, planning on taking her weapon, Godsend, to keep his position firm. However, Elspeth managed to throw the spear into Xenagos's chest, causing the arrowhead, which Nylea had shot into Xenagos before his ascension, to explode, tearing Xenagos's organs into shreds. As Xenagos died in Nyx, he did not fall to the Underworld and is thus truly gone.
