Prosperity

Prosperity was the first of humanity's ark ships, sent out into space to colonise other worlds. Eventually, the transmissions from Prosperity stopped, and it was declared lost three hundred years after its launch. The ship continued on for more than three thousand years, piloted by Ana, who was kept alive artificially. The people aboard forgot their origin as colonists, the vegetation spread to cover the interior of the ship, and the culture regressed to a tribal state. One tribe called themselves "Umans" and were lead by their Elders, the left-tenant and the right-tenant. Over time, both the oak trees and the humans aboard became taller and spindlier in the lessened gravity. (PROSE: The Lost Generation)
