The World of Kritias

The World of Kritias was created by the corpses of the two Great Gods. The corpse of Anir, The Bright God, became the day, the sky, the stars, the sun, the vegetation, and the animals, while the corpse of Kelsus, The Dark God, became the moon, the ground, gave birth to intelligence, to emotions, to destruction, and death

As life flourished, the intelligent races were born by the world, Humans, Dwarves, Elves, Beastmen, and Demons.
