Timeline

Timelines are a tier of spacetime, smaller than universes but at the same time, they can effect all of Reality. They are groups of time rather than groups of space, but they all exist at one point. Despite this, every passing moment causes near infinite other timelines to happen. Universes require deliberate action and an extreme amount of energy to be formed, but timelines are created through literally everything, from a star exploding to an atom moving in a different pattern. They are chaotic and infinite, but they are contained in the multitimeline easily, and will never exist anywhere else, as the multitimeline is a larger infinity.

De Club Franchises are mainly kept in one Timeline, but alternate versions are kept in other branching timelines. In short, timelines contain all of reality and every branch of every event that can possibly happen. Everything that happens in De Club is in a timeline.
