Demon Emperor

"In the beginning, there was only a churning turmoil of chaos. At the heart of chaos, where all things became one, appeared an Egg. Having tumbled from the vortex, the egg gave rise to the Original One. From itself, two beings the Original One did make. Time started to spin. Space began to expand. From itself again, three living things the Original One did make. The two beings wished, and from them, matter came to be. The three living things wished, and form them, spirit came to be. The world created, the Original One took to unyielding sleep..."
