Before we get into the nitty gritty, I would like to remind everyone that i don't own Supernatural. If I did, Destiel would be canon because holy crap it would have already been if Cas had chosen a female vessel. Just calling out bull crap when I step in it…

First, there was nothing.

Now you might be thinking of complete, unending darkness, but even that is something. Here, there was a complete absence of existence. There was no light to inspire anything, there was no darkness to fill the void.

There was just absolutely nothing.

Then, an idea broke through the emptiness. For just a flicker of a moment, something existed. And that something created the Darkness.

She (as she would later identify herself) was an all-consuming entity that spread blackness wherever she touched. She spread herself to all corners of the universe, filling the surprisingly limited infinity. And for a while, all that existed was Darkness.

Then, another flicker.

This idea manifested itself as God (or at least, that's what he called himself). God was a force of light that promised more things to come, and he was the one that first named the Darkness (for she only existed before, never giving thought as to who or what she was).

For eons, the Darkness and God existed alone, winding around each other as they filled what was once an endless void. Good called the Darkness "sister" and he was called "brother."

But while the Darkness was content with just existing with her sole companion, God felt a different calling, a calling to do more than exist for eternity.

God began to create.

The Darkness allowed it, for a time. The creations were small ideas, the concept of organized lights (stars) and their rotating rocks (planets). But soon, the creations became more complex and started to spread into what was once understood as her dominion.

God loved the Darkness and tried to share the fruits of his labor, his little worlds that seemed to be an extension of his own self, proof of just what he could do.

The Darkness devoured them all.

In moments, several millenniums of work were completely and utterly destroyed, leaving only Darkness behind. She didn't care that they were a part of God, that he had designed and constructed every aspect of each of those worlds down to the last atom. They were taking up God's attention, which should have been on her and only her. They only needed each other and their endless dance around the void.

But God could no longer dance. He could no longer just exist. His very self was about bringing new things into existence, and the Darkness refused to accept it.

And, for the very first time, God hated his most beloved.

God knew his sister and he knew that if his creations were to survive, she would have to be sealed away. In the deepest parts of himself, of his light, where the Darkness had the hardest time breaking through, he created four beings: Michael, Lucifer, Raphael, and Gabriel. They were made of his deep intent on sealing away the Darkness, and he called them archangels.

God and his archangels fought against the Darkness, for God's right to create. And while the Darkness was outnumbered, they were totally and evenly matched. However, the Darkness had started to develop a soft spot for the second-made, Lucifer. It seemed, whenever he fought, his heart wasn't in it all the way. The Darkness reached out to him and he seemed to respond...

… Right before he betrayed her.

It had been a trick, to distract the Darkness, and she soon found herself bound to a mark that suppressed her influence over the void. The mark was given to Lucifer, God's most beloved and the Darkness's most hated. And while she wanted to destroy God and his creations for what they had done to her, all she could do was wait.

As she waited, the void was now filled with God's light, and he used it start creating again. He created a home for his archangels, Heaven, and filled it with thousands upon thousands of angels, though none as powerful as the first four.

He filled the universe with galaxies and stars and suns and planets and moons and so many wondrous and terrible and beautiful things.

After having to seal away a particularly nasty species away in the realm of Purgatory, God decided to start working on his masterpiece on a small planet orbiting a somewhat mature sun. Unlike all the others, this work of art would not be led by his own purposes, but by their own. Free will, he called this concept. The species, he called mankind.

When they were constructed, they were presented before the angels and God declared mankind superior. He commanded that the angels submit to his new creation, and all except one did.

Lucifer, God's most beloved angel, had started to feel the influence of the mark on his soul. As soon as God had started working on these… things, the Darkness had started to fill him with the same hatred she felt.

Lucifer refused to bow and started a rebellion that would lead to his, and several angels', fall from heaven. God, fearful of the Darkness's rage and influence, sealed his beloved angel in the deepest bowels of Hell, a place called the Pit. There, Lucifer plotted revenge against his brothers, the humans, and, more importantly, his father. And it would be carried out many millenniums later, on that small blue planet.

But that's not all this story is about. No, this is just a small taste of what we must dive into, to help you understand how multiple worlds are about to collide.

Our story starts before. Before Lucifer's plot. Before the fall. Before the refusal. Before man. Before Purgatory. Before angels. Before the mark. Before the first war. Before the archangels. Before the destruction of the first worlds. Before God. Before the Darkness. Before even the void…

...There was a flicker of an idea. And that idea had a home. And that home was shared with her.
