Cyrus, the possessor demon lord is dead, but his final battle left Hawaii in turmoil. Hundreds of people are wounded, and the aftermath of a volcanic eruption has kept the survivors busy with the cleanup. Schools are closed and stores are being rebuilt. Life is almost back to normal, except for Ikelia, Eli’s mother. 

Eligor, Eli’s father, is still trapped inside the Keeper crystal. Ikelia is unable to free him, so she asks Davin, the head of the Chosen Knights, to travel to her past to when she first became the Snow Queen to find any clue that could help her. 

They learn they must go to Kaneana Cave, home to a legend about a Shark Man who lures humans through a smaller opening in the cave and eats them. So Davin rounds up the team. But what they find there might mean the end for Ikelia and the Chosen Knights.
