Oriseus suggests adding salt to the water in the diorama and a room rises beyond the arch that shuts out the falling water. The group passes through to the other side, whereupon a series of lit doors slam shut to their right. Ignoring the shut doors, the party continues westward to an unpainted wall. Upon investigation, the adventurers discover that there are actually rotating doors built into the wall. Before long, they have all passed through to a room with a chessboard floor. Each tile appears to be trapped and after a series of electric shocks and thundering booms, they manage to pass to the hallway beyond. The corridor leads to an unlocked door. It opens into a small room, painted with ocean scenes, but empty except for a large painted statue of an orange fish. Dinsdale finds a secret door to the north.
The party moves through the door and down a long hall to a large chamber that is filled to the ceiling with breathable water. Inside, there are six huge sharks swimming menacingly. On the other side of the room, there is a seaweed covered statue of a mermaid holding an urn. Battle ensues. In a fit of aggression, Dareus charges into the room and suffers a series of shark bites. The party revives Dareus three times and just as it looks as though Dareus will be pushed from unconsciousness to death, luck strikes and the attacking giant shark misses its killing bite. The last of the sharks are slain. Dareus is revived a fourth time. The statue’s urn contains a vial of brightly colored transparent blue liquid. Dinsdale discovers a polished shell in a compartment in the back of the statue. An identify spell reveals that the shell can imbue its owner with the power to breathe water. The party takes a long rest. The session ends at 7:00 a.m. on Thursday, October 1, 1372 (DR) Third Age.
