Far to the east of the Worlds Edge Mountains, across the barren, wind-swept steppes of the Howling Wastes lie the Mountains of Mourn, where the Ogre Kingdoms lie. In ages past, these snow-capped peaks were home to an ancient race known as the Sky-titans, enormous Giants of surprising intelligence so huge that would make even the mighty Bonegrinders seem insignificant. But the impact of the comet that would later form the vast crater known to the Ogres as the Great Maw forced the tribes to abandon their ruined homeland and migrate west. After a bitter conflict that saw the entire race of Sky-titans fall to the ravenous hordes of Ogre refugees, the tribes settled in this newly acquired land and the Ogre Kingdoms were born.
