From the introduction:
The land of Nendo is locked in a terrible prophetic dream. This prophecy, the words spoken by the prophets of the Mountain, has thrown its shadow across the people for ages. Now in the year of destiny, it finally has met a challenger. You see, the Mountain isn't the only force of Nendo. Drawing its strength from the unknown over the centuries, growing more and more powerful in darkness, the River now has enough might to step from the shadow of the Mountain's prophecy. Take on the role of an eternal goddess, a Rose Maiden, whose only purpose is to break prophecy and usher in a new era of wonder to a land that is dying of stagnation. Acting through her dream, a human woman in the land of Nendo, can you free everyone from blissful stagnation of prophecy?
