The Reborn Kemet: When the Celestials came from Earth, fleeing the collapsing culture and the wars that raged among their kind, they took with them a spark and an idea and let it be reborn among the tribes of Helca. They “educated” the tribes, planting “new reeds” in the fertile ground of the tribes. Unto them was given a vision they called “Ouroboros” – a rebirth or their home and the best of their attempts to free themselves from the shackles of mortality and its limited thinking.
