Exodimensional space

The exodimensional space (EDS) is the space in which the entire multidimensional system is located. It is a space where physical laws break, and matter cannot exist. Instead, to communicate between universes and mobilize matter between dimensions requires the aether, a substance that flows from the entirety of the multiverse and contains the universes, working as a shell for the matter not to scatter and disappear in the EDS, and transports matter through naturally formed cracks across the inside of the aetherial columns that form between aetherial shells. This allowed entire universes to disappear, or simple transfer matter and energy to another. Multiple artistic interpretations have visualized the EDS as an endless, pitch black emptiness in which bubbles of aether contain stars and galaxies, all of existence, and connect with one another in interuniversal flows of aether.

Behind the Scenes

The move that introduced EDS also introduced translations in Hitoku: yasuteri yasanakyum, or simply yasute for EDS, fūshūn for aether, and deneka tagyoku, or simply tagyoku for aetherial columns. These translations were not included in the canon text in order to avoid confusion.
