From the Dream Pod 9 website:
"The world of Tribe 8 was once the one we know today -- skyscrapers, modern medicine, nine-to-five existence -- but all that was wiped away by the arrival of supernatural terrors. Some called them demons, monsters or horrors, but their proper name is Z'bri. No human tongue can quite pronounce the word correctly, but if your breath is rasp and stuck in the space between agony and pleasure, you're close.
"The Z'bri came from a distant spirit realm and descended on the modern world like a plague. They were powerful, mad and magical lords drunk on the physical pleasures they had long been denied, and they caused civilization to collapse. Endless tombs dotted the lands and the survivors were herded into camps to dance, scream and die for the pleasure of the mad Z'bri lords. This bondage was seemingly endless, blasting away the memories of the "World Before."
"There were those who kept freedom alive, however. They prayed for salvation and whispered forbidden memories to one another. When even their hope was on the verge of being washed away forever, the Goddess (Tribe 8's Earth Mother divinity) chose to manifest Herself.
"The Goddess sent eight strangers -- known only as Nomads -- to the camps of a once-great city called Vimary. They taught the prisoners how to summon avatars of the Goddess and sacrificed themselves in these same arcane rituals. These avatars, powerful manifestations of one aspect of the Goddess, were called Fatimas and they were glorious indeed, imbued with holy power and divine righteousness. These Fatimas led the prisoners in a revolt against the Z'bri.
"The victory against the monsters was neither easy nor complete. In the end, Joshua the Ravager, most powerful of the Fatimas, and His tribe were slaughtered in a final conflict with the Z'bri overlord. The horrors were pushed back to the north of Vimary, but they were not destroyed. The seven surviving Fatimas together formed the Seven Tribes -- the new nation of humanity.
"Humanity was liberated, but not yet free."
