They're the main antagonists of my monster taming series project, Crack Quest. They're ancient entities brought to life by two kings with a great hunger for power using the power of Elementalism (the main way to control monsters in my setting). Unlike their kings, who wanted power over all, these two were programmed with defeating their opposite, and thus Praldabaoth wanted to destroy Adversariel and vice versa.
One day, during that dreadful war, a man without a family or a home was contacted by God, and was bestowed the four elemental guardians of the world, to defeat the two entities. After a long battle, the two were defeated and sealed back in the Information Space, the place where only imagined and thought things lie, who were not brought to reality.
