The apocalypse in Braithe occurs when the Kal Greater God of Death escapes from his dimensional prison and conquers the world , asserting himself as its absolute ruler . His energy , empowered by decay and destruction , eats away at the world , causing something of a magical nuclear apocalypse . The landscape becomes barren , with flora and most fauna in the world dying off . Not only does the natural world begin to fall apart but Xeros ' the aforementioned Kal of Death energies morphed the landscape , causing harsh landscapes and severe climates , as well as poisonous atmospheres in some locations . The once flourishing bastions of civilization where Mortals , Ulvess , and Vessan use to inhabit were specifically targeted by Xeros ' forces . The cities were razed , destroyed , or taken over , and the Akine , the animalistic , semidivine allies of Xeros were put in charge of the remaining populations that survived . The mutant stereotype comes in the way of Xeros ' foot soldiers , the very barely , almost , sort of , sapient , Kyxus . They run rampant , as the ruling authority of much of the world , Xeros himself , will obviously do nothing to stop their rampage across the world . The more death these Kyxus produce the stronger Xeros becomes . Now , since this is an actively caused apocalypse that could be ended with Xeros ' death , there are groups that act to remove the Kal from power , or , the world at large . This is largely divided between two mind sets . There are those that aim to aid Xeros in the long run , as he only intends to gain power in Braithe before breaking through its Gate , and breaching the Void , the divine plane , to go to war with his father ' s wife and the ruling Kal that imprisoned him . This is an incredibly short sighted plan . Others yet aim to directly kill Xeros , this group , led by AmusAtil , Xeros ' nephew and the Kal of Magic , seek to kill the Kal of Death , dividing his essence forcefully . In the end the apocalypse is ended when this group led by AmusAtil successfully kill Xeros . AmusAtil , being the son of the call of Life , as well as his secondary domain being Nature , releases his energy throughout Braithe and restores the world to what it was before Xeros . This has the interesting affect of causing an age of exploration , as Xeros ' death and AmusAtil ' s energy kill off a large portion of the Akine , the beasts that had been preventing Mortals and the other races from colonizing more than a couple hundred safe zones throughout the world .
