The Omniverse is everything that is. It incorporates every universe, known and unknown. There exists within the Omniverse clusters of universes that have access to each other; they share common themes, Natural laws, Common Geography, common personalities, or common organizations. These clusters are what we call Multiverses. There are many multiverses within the Omniverse.
History of the Omniverse
The Origin of the Omniverse
In the beginning, all was void. There was one in the void who explored the limits of limitlessness and plumbed the ends of infinity. He reached into the emptiness. In reaching he conceived fullness; he conceived everywhere, he conceived everyone, he conceived everywhen. He pulled his arm back from the emptiness and he held everything in his hand; it was a smooth orb that hid none of it's contents. It was full of darkness and light. From The Omni
, he made the first children, and with the first children he set about making a place for them all to live.
The first children stepped out and found a firm foundation. they looked about and saw that their progenitor had set the Omni into the foundation. Around the Omni, they built a forum
and around the forum, they set their homes. Their children set their homes just beyond those and their children set theirs just beyond those. As each generation piled onto the next the first city arose they named it Zion.
For Millennia the people of Zion grew and spread. They dispersed across the heavens and filled worlds. In their growing and spreading, they grew apart. Those that were brothers became diverse in form and creed. Worse yet these brothers came to hate one another. Squabbles became wars. the years of war came to outnumber the days of peace. there were those that came to believe that the varied races and creed could not coexist.
Their reality was held together within the Omni; it would be through the Omni that they would achieve "peaceful" separation. there came a Worldbreaker
with a great hammer
; The Worldbreaker struck the Omni. The Orb didn't give. The Worldbreaker continued to assail the Omni with blow after blow; it would not break, but under it's surface, fissures formed; and with each strike, the fissures multiplied. The Worldbreaker grew weary and collapsed baffled that the orb withstood his onslaught.
Outside the forum, the effects of the attack were evident. The initial blow shattered reality into many divergent facets and each subsequent blow shattered those facets into branches and sequels. As reality split, entire worlds and sectors were pulled into their own separate quantum streams creating new self-contained realities. theirs was no longer a Universe, but a multiverse of multiverses, an Omniverse.
