Bobby finds himself in the territory of Cloral, a world entirely covered by water, which is nearing a huge disaster. He learns that it is up to him to help rid the area of marauders and locate the legendary lost land of Faar, which may hold the key to Cloral's survival.

With Saint Dane seemingly on the verge of toppling all of the territories, Pendragon and Courtney set out to rescue Mark and find themselves traveling--and battling--their way through different worlds as they try to save all of Halla.

While Pendragon is trapped on Ibara, Alder returns to Denduron and reluctantly goes into battle again, and other Travelers face obstacles of various sorts, Saint Dane gains the power he seeks on Second Earth and makes his push to destroy and rebuild Halla.
