Ten thousand years ago, the Great Lord Laius sealed away the Great Monster Sihn under an endless ocean. This ocean now makes up the surface of the new world, and high above rests the continent of Eternity, where people wield the power of the gods through fragments of their souls. When the great city of Calarina is turned to rubble, a young girl known as Alicia must set out on a great journey across the expanses of Eternity, and learn about the origin of Sihn, Laius, and everything in-between.
