Akasha

"Akasha [...] the soul of Creation, as it were. Impossible to truly behold, but instinctively familiar to all beings. This is where mana and prana all come from and return to. Or so we can claim to understand - No one knows where the material world stops and where Akasha begins, whether or not Akasha can think for itself, nor how it can possibly fuel all things."

- Zev Raregroove

Akasha was a metaphysical location that some believed to be the highest dimension of the BZPB Multiverse and the "source" of all of the facets of existence.

Description
Zev Raregroove believed Akasha to be the "soul of Creation"; the source of all energies that existed in the BZPB Multiverse and the place where souls were born and returned to after death. Zev once compared the relationship between Akasha and the mortal planes to the relationship between a mother and child, with that mother's love being the energies that fuelled the multiverse. Akasha was also theorized to exist outside of time and contain the "Akashic Records"; information about all possibilities and events of the past, present, and future. Artifacts such as the Sacred Weight Stone and entities such as Nu-13 drew energy directly from Akasha to fuel their powers.

Though "Akasha" has been shown to exist in some form, its true scientific nature and relationship to other "higher" dimensions, such as the Hyperdimension, Internet Dimension, and Knowledge Dimension, remains unknown.

History
Mistgun once recalled that the Sacred Weight Stone was able to draw on a small portion of energy from Akasha and concentrate it over time to channel massive amounts of mana into the Suiten Taikan Kagami.

In 150,082 CMT, a duel took place between Zev Raregroove and Wulf Orden, and their respective familiars, Asabana and Garvantine, in a tower on Hei Fon 4. When Garvantine used Tournesol to unleash a spell of unstoppable destructive power on Zev and Asabana, the latter two attempted to counter it with the defensive capabilities of the Crowned Mirror. The four then discovered what happens when an unstoppable force meets an immovable object: the two spells struck a perfect harmony and offered a brief glimpse into Akasha. While Zev explained to Asabana what he thought Akasha was, its light revealed two characteristics of his true form; teal hair and glasses, before it faded and the group found themselves back on Hei Fon 4.

Later, Nu-13 demonstrated to Blackout that she served Akasha by briefing opening cracks in the fabric of reality to reveal Akasha's light.
