After securing the rope, Erdolliel dives down and Kushnak and Nethezar jump after. While Erdolliel swims, the other two sink to the bottom and walk. The passageway heads south, then opens into another room. Erdolliel leads the way, swimming to a pillar in the middle of the room. The elf swims to the surface of the water and grabs onto a ladder on the column. Tying the rope to the ladder, the others are able to half-swim, half-climb to the surface.
Once Kushnak and Nethezar breach the surface, they see what Erdolliel saw before. The column extends 10 feet above the water, and the ladder on the column covers only those last 10 feet. The room is light by pale blue everburning torches affixed to the walls.
Atop the column is a large lever. And a bridge, at the same height as the column, heads to a door to the south.

[sblock=OOC]I told Ti before, the passageway you just came through is, of course, also underwater. I have no idea why the map-makers didn't also make it blue.[/sblock]
