Roger Torrents and Israel Mckinley are reeling from the events of the Spring Equinox Festival, and they fear the Soul Alliance is being torn apart. Roble is off in the Soul Freezer village, and Slick and Slime are nowhere to be found. The Chosen Ones are left alone to set sail on the high seas in search of the Soul Stones, where they must face unimaginable obstacles as they break into evil island shrines and battle vicious wardens, knowing Chanulville and the Central Orb's future depends on their success.

In the meantime, Slick and Slime embark on the urgent mission of collecting the pieces of the Dark Prophecy of Malgorpeo. As they delve into Lord Rayo's past, they uncover far more horrifying dangers and details than even they could've imagined. As the scroll is brought together piece by piece, they slowly realize that stopping the darkness of the prophecy may only leave them with one choice. One where not everyone will survive or live to remember Chanulville.
