Behold, The New Has Come - Barrett Arcadian

In the beginning, energy decided to exist. Out popped all the gods, one right after the other; Pario, Fastus, Profectus, Passio, and Mortem. In their great and infinite wisdom they created the six realms with the intention to keep separate all the beings that lived within them, and their angels the only ones blessed with the ability to travel through them.

But some several thousand years ago, something managed to kill one of Pario's angels, traveled the different realms, and made a deal with thirteen humans who lusted for power. The birth of the human mages made the realms come crashing together into one big Cataclysm that threatened to destroy the very fabric of reality. Whole civilizations were wiped out in the ensuing catastrophe that ended only once the angels sacrificed nine hundred and ninety-nine of their own as their gods disappeared.
