Restricted by the laws of heaven, the gods had no choice but to sit back and watch the humans of Earthland destroy each other, their wars never seeming to cease. One day, however, the powerful Gaia had had enough. Along with six disciples, Gaia exited heaven in an attempt to set things straight on Earthland -- or so he led his disciples to believe. Upon his dissension, Gaia became greedy for power, summoning an army of monsters to parade with him throughout the entire world and locking his disciples into one of the many new magical towers he had constructed.
