Since he was a boy, Yorn always wondered about the origins and mysteries of the "Edens", two floating cities that turn out to be more sinister than they appear. Yorn's encounters with the Edens begin when his father is murdered by assassins from the two cities and he finds out that he's going to be next. Soon, Yorn has begun a quest to find his long-lost mother and discover the truth about his family. In these episodes, Yorn and the others finally reach Rubeed, only to find that the princess is no longer there. Meanwhile, Yulgaha is advancing troops towards the city to make sure Yorn can't escape.
