Stingray arrives at Arcadias last known position and encounters the galleon, which does not respond to Troy's hails. Shore and Phones board the ship and find its upper decks deserted. However, they fail to notice a platform built into the floor of one of the cabins and are lowered into a watertight section in the vessel's depths. There, they are held at gunpoint by an undersea pirate called Idotee, who reveals that he has converted the galleon into a submarine and that he used its cannons to sink Arcadia. Idotee now intends to kill the Stingray crew for their crimes against the undersea races.
