The Realm of Caelum was a strange realm inhabited by spectral beings of concepts known as Gods. It has neither bottom nor top. All ends equal, and their mission was to spread their existence across all realities. Such was the creation of faith and religion. Their blessings and their concepts get better as long as something believes in their existence.
And if something doesn't believe them, the Gods will do everything to make their existence known. They were one of the annoying spectral races and were also one of the oldest ones along with the World Administrators. Atop the apex peak of existence, it has rather been a while since they tried dipping their divine selves onto the Realm of Piksyon.
