Before creation there were the Abyssal Ones. They were the only things that existed and they inhabited the lands before creation. An endless field of nothingness that extended into infinity. These beings were made up of what we now call Blackfire, the raw essence of nothingness. The Abyssal Ones were all equal in power, and they never had reason to fight or disagree with each other.
Then one Abyssal One grew tired of the constant nothingness and created the first realm. In that instant a portion of the land before creation became a new place, something that had never happened before. The Abyssal one that did this tied its very essence to this plain and became far more powerful than the Abyssal Ones. The Blackfire that formed him changed. What was one pure nothingness had created something and became Whitefire, the power of creation. And this Abyssal One became the first Primordial.
The Primordial saw the power he had gained and looked upon the beauty of his realm, and decreed that his realm should expand to consume the entirety of the land before creation.
The Abyssal Ones tried to resist him but found he was so much greater than them, so they to began to create their own plains and also became Primordials. But the Primordials all looked upon their plains and saw the beauty within them. And so they said that their plain should grow to encompass all other plains and what small parts remained of the land before creation.
And so the Primordials went to war with each other. Each one fought alone, for they new that only their realm should be the one that encompassed all things. And so this war went on for eternity. Time and space were were born and torn apart in an instance, Primordial fought Primordial in epic clashes that would destroy a lesser beings mind if they were to gaze upon it. The few remaining Abyssal Ones could only cower and hide in the scraps of the land before creation that had been left untouched.
It seemed like the war would have no ending, but then four Primordials formed an alliance, they thought that they would rather infinity was split between their plains than risking their deaths and the consumption of their plains. So these four Primordial began to kill the others. One by one the other Primordials fell, till only those for still lived. The four remaining Primordials gazed upon their plains.
Lucifer, the Primordial of Hell, suggested that in order to prevent the four from turning on each other that they should create a pact. They would create the pact and place their own essence within in it, so if they broke it they would be destroyed.
The first to agree was the one many on Earth call God, the Primordial of Heaven. He was benevolent and trusting and had grown tired of the eternal conflict.
The second to agree was the Primordial of Earth, Gaia. She wished to return to her realm and to create new life, not to continue a war that could be ended with words.
The last to agree was Oberon, the Primordial of Fairy. This was not through any wish to continue the conflict, but he was cautious, and he was right to be as Lucifer was a cunning creature.
The pact was formed. It was a simple thing, the other Primordials could not enter, affect or contact anything or anyone in another Primordials plain as long as that Primordial lived. And with the pact made the four retreated to their plains.
