Mortal Realm

The Mortal Realm, also known as the Universe or simply existence, is the realm of being where everything, from planets, people, and much much more, exist.

Creation
The Mortal Realm was created by the Dark Guardians, a group of gods who reside within the Astral Plane, around 14 billion years ago. They then went on to populate this universe they had made with life, technology, and many other things.

From this point, they allowed things to occur naturally, such as evolution of life and the formation of stars, galaxies, and planets, mostly having a benevolent presence within the evolution of the Mortal Realm. When the time came, however, the Dark Guardians would act as their nature was (in a neutral manner) and effect universal events.
