Standard Branch
The Absolute Void is the cosmic layer between the Antibox and Absolute Nothingness. It is the first real cosmic realm on the Hierarchy of Realms, even though it is practically nothing. It is not a "thing", rather it is the absence or "void" of such things - it is nothing, but not Absolute Nothingness. Entering the Absolute Void leads to absolute erasure from existence with no coming back, as the Absolute Void inevitably leads to Absolute Nothingness. It is fated that all things in the Supracosm will eventually enter the Absolute Void, no matter what. This includes all realms, dimensions, timelines, verses, concepts, beings, consciousness, mathematics, logic, information, existence, non-existence, entities, and everything else within the Supracosm.
The Absolute Void is the second lowest "realm" or "structure" to exist under the Flow Narrative's cosmology within the Supracosm.
