Chronal Cosmos

undefined:

A chronal cosmos is a cosmos, metalayer, alarach, or layer cluster that exists as different timelines of the same world or worlds. They are comprised of individual chronolayers, with or without a "central" layer. They do not interleave the same way those of a polychronal layer do, but still intrinsically linked in a sense.
