Pocket Between Time



Pocket Between Time (時のポケット, Toki no Poketto) is an endless void-like phenomenon found between timelines from nearly all inhabited structures within the. Despite its existence, it is a rarely-known concept that only a small handful are aware of.

Within Fate/Advent, it is explained by Abe no Seimei that the Pockets Between Time are both the weaknesses and advantages of planets, like the, where they hold little to no jurisdiction, being considered a fail-safe if something unplanned were to happen to them. If all timelines were to somehow be destroyed, a Pocket Between Time could gain enough influence within the husk of a planet to bring about a new Genesis. Inversely, if left unsupervised, an inhabited Pocket of Time could gain enough momentum to overtake the Main Timeline, making it the new Main Timeline and overwriting all other timelines.

Seimei further claims that there are an infinite amount of Pockets, similarly to how there are an infinite amount of timelines, but all of them lack any sort of concept, unless concepts are applied to them gradually over time. It is due to this, that if one were to happen to enter one, they would immediately be ejected out back into their previous area, as the space is unable to hold something that which cannot exist within it. This results in an initial concept, whose purpose is to create a habitable space, having to be applied from outside the Pocket Between Time.

There have been some observations that Pockets Between Time can be created from something that doesn't exist anymore. Such an anomaly, thus far, has only been confirmed to happen from destroyed timelines, resulting in the creation of an Ort.
