The chaotic magical energy of the War of the Magi caused an influx of Celestial and Abyssal forces to bleed into the mortal realm, giving rise to myriad beasts, curses, and curiosities. Humans mutated into many different forms including orcs, fae, mermen, and the like. All manner of fantastical creatures from dragons and goblins to unicorns and sprites began to populate the earth. The sudden appearance of supernatural beings ushered in an age of chaos that caused all major civilizations to fall and their technology and knowledge to be mostly lost.
