Ancestor-universe

Ancestor-universes were prior universes from which realities such as N-Space were descended. They were so named because the creatures within them often spawned new universes (for this is how universes are made) called descendant-universes. It was difficult to make a new universe which differed too much from one's own universe, meaning that unigenetics could be traced through a lineage which had evolution over time. (PROSE: The Cosmology of the Spiral Politic)

A clear example of unigenetics of ancestor-universes could be seen in the Known Worlds, which were two related families of universes: one a collection of parallel universes where the Roman Empire never fell and the other a collection of universes where Nazis won World War II. These clusters likely shared a similar ancestor-universe interested in testing what would happen if history were altered in this way. (PROSE: The Cosmology of the Spiral Politic, Warlords of Utopia)

The Kotturuh believed they had been spreading the existence of mortality in the prior universes. They did the same in the universe during the Dark Times and believed they would do so again in subsequent universes. (PROSE: The Dawn of the Kotturuh)
