The Universe, also referred to as the First Universe or the Mortal Plane, is a multi-layered plane of existence which is composed of the space-time continuum, the first Universe to be fully created by God and the Light Beyond the Stars, and the Universe of which other Universes were based on. This Universe follows physical laws, and is separated from dimensions such as Heaven, Hell, and Purgatory, which can only be accessed from this realm through gateways and death.
It is considered the most treasured Universe in all creation, and the one under the most protection by Heaven.
