Multitimeline

The multitimeline is an infinite group of timelines residing somewhere in The Large Void.

this is where every timeline is kept.

despite it being used to contain timelines, it’s still a physical place that can be accessed and explored. Touching timelines in the multitimeline will manually cause trillions of timelines to split off of that timeline. Doing this will activate the defense system of the multitimeline, and you will be teleported to the first layer of the void, so it’s still a dangerous place to be.
