When the Blood Moon made their prison weaker, the demons flooded out across Ashan and wreak havoc. The armies of the land, who had not faced a horde of demons for a long time, were unprepared for the fierceness they faced, and they were driven back. The wizards of the Seven Cities, realizing that they needed new frontline fighters for their war, injected human slaves and prisoners with demon blood, and the orcs were created. The orcs could fight with a fierceness that matched their demon relatives, and the armies of Sheogh were driven back to their homeland and imprisoned once again.
