Realm

"Despite what many may think, a realm isn't just simply a kingdom, a country, or an alternate dimension, a realm is a self-consistent universe with its own laws and history, all connected to the real world through an invisible thread."

- Matt Wright.

A Realm is a self-consistent universe with events, and often other elements, that differ from the real world.

Overview
The gods have stated that all realms are in a constant state of flux, shifting like endless dreams. However they're a different concept from alternate realities. Thousands more realms, known and unknown, are stated to exist. Travel between realms is done via various portals and dimensional rifts. Moreover, many of these realms were fashioned by the gods themselves during the universe's youth but this was mostly during their warring conflicts against their primordial predecessors who at times were their own parents as well.

Some of these realms in question were also said to have been fashioned by the mutilated corpses of their primordial parents with this motif being found in mythologies like the Norse and the Mesopotamian. In such cases, the would-be rulers of the cosmos attack and kill these ancient primordials and fashion the many layers of the world with a piece of their body. This in turn becomes a realm. They are all connected to the branches of the Tree of Life. These realms are also said to contain beings and creatures known in myth or even unknown by humanity.

Most pantheons has at least one realm to itself. For example, the Norse pantheon has the Yggdrasil tree, which is "inside" the Void of Oblivion, Ginnungagap. Yggdrasil itself also serves as a bridge to other realms, as it can lead the gods and even humans from Asgard to Midgard, the Norse name of the human realm. Realms are sometimes seen as an alternate universe even if that is factionally incorrect though some realms may have their own dimension with it having its own physical and temporal laws. All realms exist within the Omniverse and can be connected and accessed through black holes, white holes, wormholes or interdimensional passages between the "gap" that separates each universe.

Description
Each realm is different from the other, and may be completely different from the mortal universe where humans live, for example: there may be a realm where time runs backwards from the human perspective, or a universe where time runs faster, making 1 day on Earth is 200 years in the realm. However, a realm that always catches the attention of human beings is the abode of God and the angels, Heaven, also called the Pleroma. One of the Bible writers, Paul, wrote that he was taken to the Third Heaven in spirit and saw ineffable things. Which means that Heaven is a realm beyond the imaginable, being indescribable to human beings.

Another realm that deserves attention is the Outerverse, created by God to trap the Old Ones and prevent the annihilation of all reality. The descriptions of this dimension are beyond imagination, totally inexplicable for any human being and even an angel, it is a space of pure nothingness and chaos that transcends all conceptions of being, size and limits, as the genuine and definitive infinity beyond the mathematics of any cosmos, of which all existence is but an atom, residing beyond a vast hierarchy of "unlimited void beyond all thought and entity."

In addition to this realm, there is also The Empty, a mysterious place that is said to predate Ayin and Khaos, ruled by an eternally sleeping entity called only "The Shadow". This place is said to be beyond the powers of God Himself and that none other than the Shadow has power and authority from that place. The Empty also serves as the afterlife for most supernatural beings.
