Thousands of years ago, the demigod children of the goddess Sonova murdered their mother out of envy for her power, but 300 years ago the demigods mysteriously vanished, leaving a barrier that divided the world into four separate nations. Ryn, the futuristic and technologically advanced society that focuses on hedonistic pleasures of sex and drugs; Miizu, the matriarchal samurai-era nation of honor and discipline where women are in power and men take the nurturing roles; Ghald, the steampunk land of religious zealots where it''''s society are working for the church or grueling over hard labor; and Paiyi, the nation that refuses to take any technological advancements after they had nearly caused worldwide genocide in the past; all nations governed by the Central Government and their spies known as The Phantoms.
