The story begins after Adol's ship is attacked by a fleet of Romun ships. Forced to sail into an unknown area, they encounter a large storm. Adol is swept off the vessel while trying to rescue a fellow sailor and washed ashore by the vortex that surrounds the Canaan Islands. He is found, unconscious, by the daughters of the chieftain of the nearby Rehda village, Olha and Isha. The girls take him to their village and lay him to rest in their father's house. Adol hears them talking about him and wakes up briefly, afterwards going back to sleep because of his exhaustion. His adventure then begins.
