Mother Sea

The Mother Sea is a location or higher dimension which exist outside of the normal universe possibily between the Lilith Multiverse.

It can be accessed and connected to with manipulation of gravitational force this however, will destroy a universe that connects to it. It is also described to be connected to Taimanin arts, Inner Demons and the mysterious inhabitants the Aion.

Structure
As the the highest overarching multiverse structure, it contains "everything" and needs to be scaled down.


 * Entire grey area is the "Mother Sea".

All Lilith Multiverse, universes and possible "what if" scenarios exists in it, the Old World, New World and many Another Worlds included. Multiple Human and Dark Worlds pairs, connected by one or multiple Demon Gates or single worlds exist on the lower half of the Mother Sea. The total number of realities could be infinite. These worlds are 4 dimensional but with a Demon Gate one can move between them. The Brain Flayers are a species that can travel between such worlds and conquer some of them.


 * Seen as green, red or blue circles on the lower half of the image.

The upper area of the Mother Sea contains the Otherworld, a realm of Gods and Devils, which is a higher dimensional than the spheres below. However, still is contained as part of the larger Mother Sea. One could imagine it floating on top of water like oil. That realm is 5 dimensional and the Gods and Devils of it can enter lower realities but are very weakened by it, as they need to reduce their true power.


 * Seen as the brighter upper grey half of the image. Separated by the grey line.

If two worlds merge, they are annihilated sinking deeper into the "Mother Sea" but create a "splash" on it, the "droplets" of the splash create new worlds. This is seen in the "Vampire Asagi" ending of Taimanin Asagi 3, which created the ZERO Universe and its different bad and good routes worlds. This creation process has happened multiple times in the past..


 * Second image. Worlds merge, create fusion bubble that after that turns into New Worlds.

History
Edwin Black mentions that the Human World and Dark World are nothing but drops of water, floating in the mother sea. Both were infact formed out of the Mother Sea.

All main game universes and possible universes have been created within it, and beings called "Aion" came from it visiting the Human World and Dark World. They created the first Vampires which migrated to the Human World and changed into the progenitors, later mixing with Humans and became Taimanin.

The two characters mentioning the Mother Sea, tend to be Igawa Asagi, Inner Demon (Kage) and Edwin Black with both viewing it as something much higher than Human and Demon understanding. As all information comes from cryptic sources not much more is known.
