Genesis Era

42 BYBP - 15 BYBP (42 to 15 billion years before Praevoricor)

The moment existence and nothingness apparated, then spawned The Overarcher, Pre. An amalgamation composed of all-encompassing consciousness and sentience. It's imposed will became reality and their power, limitless.

Overwhelmed by the cruelty of consciousness, the Overarcher:  Pre  ripped itself apart and unleashed the Overarching Deities into the universe. Following this, they proceeded to create the Inner Planes and Spheres of Influence to reside in.

Innumerable clashing energies and emotions welled from within The Overarcher: Pre, and it was driven to divine madness. It was literally ripped apart from this, as  Pre  bisected itself, releasing it's kindred and simultaneously beginning time and creating matter.

These beings of sentience and consciousness are known as the Overarching Deities and emerged with a need to create, form of self expression for gods. It was their art. The unlimited amount Overarching Deities are separated by origin into three Realms, these realms are then divided by nature into seven Houses, where countless deities may fall into.

Amidst the experimental Elemental and Energetic Chaos, the Silence Image of Neutrality:  Inritu  sought to create a plane where entropy would not run rampant, a neutral plane. He then invited his kin to create a sphere where each of the artists could incorporate their unique influence, thus creating the Prime Material Plane.

Many deities left the Elemental and Energetic Planes to dedicate their attention to the material universe that was being created, as this was like no other. This plane was universal, not pertaining to any polarity nor element.

Spheres of Influence
Deities which conflicted too greatly with each other went on to create their own domains, known as separate Spheres of Influence (Crystal Spheres) within the Prime Material Plane.
