Yin and Yang. Two energies, as different as day and night, yet united as one. Yin governs over all that is Cold, Evil, Dark, Dead, etc, while Yang is the leader of all that is Warm, Good, Light, Alive, etc. They are in everything, and they are everywhere, but they come from the center of the universe.

As the result of the unification, Cosmic Energy came to be. It stretched across the vast and empty space that was the universe, and wherever it went, stars, planets, and other things formed. When a solar system was created, a new thing began. It was known as life.

When life formed, part of the energy broke of from Yin and Yang, and traveled many light years to be implanted into one being: the Human. Inside the human, the energy took shape and developed the ability to think, thus, at that moment, it began to tell the human of their origins, the way the energy worked and the balance was kept, for without balance, everything falls apart.

And the human listened to the energy, which deemed itself a spirit. With it as a guide, the human learned how to live, and how to keep in harmony with nature. When someone cut down a tree to use for building a hut, they would plant a seed in its place. When someone killed an animal for meat, they would be sure to use all parts of the animal, so it would be unnecessary to kill another one. As the humans learned, they discovered something new about them. They could manipulate, control one of the four elements at will. The spirits told them how to use their powers, and they grew stronger. When one manipulator became the first master, the spirit underwent a transformation. Inside of the person, it changed its form from human to animal, and then emerged from the body. It was now external, but it kept a mental connection with its body and never left its side. From that point on, whenever a human mastered his/her element, the spirit would change form; it would become a dolphin for water, a dragonfly for air, a puma for fire, and a bear for earth, and it would leave and protect it’s body. But this was also dangerous, for now that the spirit was external, it could be killed easily by another spirit.

Soon after a group of humans became masters, they left the village where all of the human beings were and went to explore the world. What they found was incredible; a new environment, not just one, but thousands. The humans recorded what they saw, and their spirit guides told them what they were, for they knew about everything associated with nature and the energy. They returned with many stories, and, surprisingly, new abilities. While they were exploring, they stumbled upon several gems. They were elemental gems; whoever touched one of these gems would be able to control a new element, until they learned all four.

Thousands of years later, and the small village where all humans once lived has disappeared. Instead, hundreds of new villages and dozens of giant cities lined the face of the planet. But knowledge that the spirits knew never died out, instead, it grew. Some cities and many villages now built temples too Yin and Yang, even though they knew full well that Yin and Yang was swirling energy, not physical things like the spirits were. But still, they worshipped this energy for creating them and the environment around them, and they still kept on with the ancient ways of keeping in harmony with nature. But not all did.

Some humans have turned greedy and power hungry. They wish to discover the portal to Yin and Yang, and when they are there, they want to steal the energy for themselves, which would make those people the greatest and most powerful beings ever to exist. But doing so will cause the delicate balance to tip and everything will fall apart, causing chaos and destruction to everything except those people, for they will be immortal and indestructible.

Now, to stop these people, several humans must join forces and find a way to fight these people and in turn save the entire universe from a catastrophic end.
