Eons ago, powerful runes were left behind by a mystical force.
When these runes awaken, they are so powerful that they create abnormalities and chaos in the world such as storms, drought, floods, and all sorts of natural disasters.
In order to protect their people, the kingdoms of Cytos band together to find a way to stop the runes.
They eventually found the key to their problem - they needed a container. By putting the runes into a physical body, they were able to harness the power of the runes. However, the beings born from this process were not humans. The people call them Arcais.
Physically, the Arcais look very much like a human. However, there are many subtle differences such as the colors of their hair, eyes, skin, and occasional traits and birthmarks which diverge from the norm. Another difference is that the Arcais has the ability to control the elements. Depending on the element their rune used to have, they have the ability to use it as well.
With their power over the elements, many people have come to realize how dangerous they could be. The rulers of the kingdoms also took noticed, and slowly the concern for power started a war. The peace that carried out was tarnished, and it is now a race between the kingdoms to gather as many runes as possible.
And that, is the start of our story...
