Realm

A Realm was the name given to a dimension occupied by a single world.

The Realms were created by the Elder Gods who split the One Being through the use of a Kamidogu. Despite its separation from its form, the One Being would subtly influence inhabitants of the realm to re-merge the Realms back into its true form. Raiden cannot go into some of these realms because his powers weakens.
