Long before your time, four gods discovered their magical powers. By combining the power and the will to create something unheard of, they created the land called Arihasa.
This land was supposed to be peaceful, but soon got ruined by the foolish nature of the population. War broke out and divided the gods to different continents, where they continued the war against each other.
Now, 580 years later, after the start of the conflict, you set foot on their world, which is no longer what it was supposed to be. This new world, once thought to be peaceful, is now in ruins. You can however still find the mysteries of Arihasa.
