While swimming in the ocean at night, Nita encounters a dolphin (nicknamed 'Hotshot'), and Kit reports the local rocks' memory of disaster.

In the following night, they are carried by the dolphin to a nearby beach, where they see a pack of sharks attacking a humpback whale wizard named S'reee, whom they rescue.

As the Lone Power's binding weakens, large kraken attack the wizards underwater, and volcanic vents become active.

Thereafter the Celebrants descend into Hudson Canyon, where they are attacked by kraken and other monsters until they reach the Sea's Tooth, where the Song is held.

A rough epilogue then forms in which Ed appears in 'Timeheart', the Heavenly realm preserving affectionate memories, to Nita and Kit.
