In the beginning when God was creating humanity, he decided the only way to get his perfection done right was to create a energy pulse that would run through the Earth at all points of both land and sea. God created the energy pulse and dubbed the name for it "Leyline". The energy did succeed creating life as God intended too. His only wish was that the "Leyline" to not be discovered by the humans. Now one would think that the energy was discovered during the "apple" incident but no it was many years after.
One day four humans and their followers discovered the "Leyline" energy and thus decided to toy around with it, maybe bend it to their will. God, being all knowing, discovered that a large group of humans have found out about the "Leyline" energy. Being furious he decided to curse them all. The first one, Adam, would get the curse that when near the "Leyline" energy it would make them feel weak, and giving one a slow death, being human forever more. The second, Fenrir, would get the curse that would turn him into a beast when a moon is full and bright at night. The third, Nosferatu, would get the curse of being an unliving soul and to pray on humans sucking life out of them. THe last one fourth one, a unknown, was given the curse of knowing the Leyline energy and toying with it, but at a cost of losing their humanity the more they use it.
God then left them with their own curses and disappeared from them all, only being a watcher. However the four would learn how to control the curses and be able to live throughout their daily lives. First one to control was the Fenrir types, later dubbed Werewolves, controlling on how to shift from human form to the beast form at will. The second was the ones, later dubbed Witches, being able to save their human forms while toying with the "Leyline" energy under spells and stuff. The last, Human, being able to save those they call scientists to invent things in order to survive in the "Leyline" energy and creating a drink that would allow all humans to survive in areas where the "Leyline" energy thrived. Nosferatu, dubbed Vampires, would be able to create certain bonds and items to help the feel alive without the need to feed on so many innocent souls. When the four were able to control the curses they all agreed to keep them a secret from the rest of the world, to make sure the rest of humanity wouldn't cause a panic if discovered again.
These four would soon bond alliances with each other and create consoles in the process. The Wolves Console, Legion of Witches, Vampir Courts, and Human League. Over time the peace would soon end and all would be at war with one another making the humans change their name to Hunters Core in order to wipe out those who dare disturb the peace. War would be over and the Hunters Core would be the victor, making rules and laws for the others to hopefully follow. Many years after past since the war and these consoles still live to this day. However they're talks about the Vampir Courts losing hold of their own kind and it may start another bloody war that could end them all.
