Dimensional Planes of Existence

The Dimensional Planes of Existence are the different planes that comprise the universe as we know it. These planes were created at the time of the universe's creation, and thusly are connected in some way or another, whether through abilities created or gifted onto the residents of one of the planes or phenomena that occur on the different planes.

The First Dimension, also known as the Mental Plane or the Emotional Spectrum  is the least complex of them all, as it is simply a manifested form of all emotions and thoughts of living beings, mundane, mythical or divine. It is home to several beings of manifested emotions, known as Emotion Titans and Demi-Titans. It is also believed to be home to the god Cthulhu and those within his pantheon.

The Second Dimension, also known as Limbo , is one of the least complex of all the dimensions, as it is simply a manifested form of all things chakra, and a potent well of said energy in and of itself. It is home to many fearful Bijū-like creatures known as Chakra Beasts that prey on any person foolish enough to transverse the thin dimensional divide to enter their realm.

The Third Dimension, also known as the Physical Plane , is one of the only places where organic life exists naturally, and is home to the "core" universe. It houses large planets most with some form of life upon them, and the home of the normal Shinobi World. This is the place where the planet Gaia resides.

The Fourth Dimension, also known as the Natural World , is one of the only places where organic life exists naturally, and it is directly parallel to the Third Dimension. This is where the families of the Summoning Contracts reside, and it exists as a large well of Natural Energy that feeds directly into the Physical Plane via several different methods, such as ley lines and various portals and entryways throughout both.

The Fifth Dimension, also known as the Afterlife or the Pure Lands' , is the most complex dimension due to the fact that its residences are spirits, the Angels of Kami, or the Demons of Datara, and it acts as a pathway to the Shinigami for wayward souls. No living being can exist within this plane for extended amounts of time without passing on themselves, making it very dangerous for anyone living to travel there.
