Legend has it that in an era older than Chaos, there was a silent torture between heaven and earth.
There was no thunder, no fire, just a blade carved from pure pale bones, cutting through the eternal night. What it cuts off is the radiance of the stars, the crown of the gods, and the lines of the avenue that build the origin of the world. The divine blood is like a waterfall, staining the riverbed of time red, and the fragments of the law rustle down, accumulating into the dust of later generations of civilization.
At the end of the punishment, the bone blade loses its divinity, gathers away its fierce glow, disintegrates into its most primitive base state, and disperses into the endless reincarnation, waiting for the next "inopportune time".
It has a name that has been deliberately erased by the heavens and is only recorded in twisted symbols in the broken pages of taboo books——
Heavenly punishment.
Later generations called it: the period of the fall of the gods.
