[sblock="OOC"] I'm going to assume that Three Flowers climbs down as well, since there's no reason for him not to. Blackrat has exams at the moment so I expect his posting rate to be a bit slower.[/sblock]
[sblock="Second OOC"] Concerning light - note that Jar'Thol has the sunrod to hand (it still has at last 5 hours of use to go, I reckon on about an hours worth of exploration so far) so light without the enchanted pebble is not an issue. Edit: Ninja'd by WD![/sblock]
The group splash down the short corridor and come to a round, domed room (about 30 ft. diameter). Several other stubby corridors lead away from it (eight in all, equally spaced. The light of the sunrod is enough that you can tell that the three opposite, at least, are only about 7-8 ft. in length.).
Walls are made of cut stone, all neatly dressed but undecorated. Knee-high water spreads throughout the rotunda and side corridors.
On the far side of the room, the three grey humanoids are huddled in a group, engaged in a squabble of some sort which they stop as you enter, and turn to look at you.
They are human-sized but wiry and emaciated. Lank black hair hangs in a fringe around bald heads, their eyes glow with a dark green light, their noses are withered away and their teeth seem sharp and fang-like.
They wear only scraps of tattered clothing, and in their hands (fingers tipped with long, filthy claws) they each hold a selection of treasures - one holds some gold dishes and goblets, one a selection of beaded necklaces and a jade carving, and one holds the statue of the Great Mutta (or, at least, one that meets the Vashti's description perfectly).
[sblock="Jar'Thol"]
You reckon they are malignant spirit creatures of some sort, but their specific type is not something that you are familiar with.

One other thing to note:
As Three Flowers descended the ladder, he noticed that the crack in the wall of the room above gave a little groan of protest and shifted slightly. The trickle of water into the room above has grown slightly in its rate of flow. Nothing to worry about at the moment, perhaps...
