There has been multiple timeline inversions and incidients over the timeline of existance.
There is personalised timeline correspondences and affinitys, each coinciding with a beings lifetimes. Some altogether entangled with majoritys of beings: of the same species or collaboration - depending on significance, partake of what they've done and resolution to an existence out-take in reality.
Many though, are primarly independently based timeline merges on a beings fate, capablity and destiny - even on just foresight.
Mostly based on affinty to a projection of what a being can do.
- viewed in visions, contemplation and in clairvoyance
e.g. space races in ships, realms coinciding & species interaction etc.
