Exploring an Alien City

Well the group finally made it to their main objective by arriving deep underground to a city built by the Demon-fish millenia ago. This was after they had to overcome some obstacles including a couple of very big insects like a giant spider and scorpion. Then they dealt with the ghost of a trog but were not aware that it was a demon-fish using some of its abilities to hide from them. From there they have traveled close to 2 miles underground and at least 50 plus miles from the surface.
They found where the ancient artifact was that held the waters at bay and they destroyed it but not before they encountered some sort of brain collector that almost decimated the party with a well placed confusion spell. The results were nasty as the group started to fight itself as the Half-Ogre barbarian pounded away at the artifact.
Then the relic was finally destroyed and the group realized that the waters were about to pour in. Now for the second part of the plan, to destroy whatever was making the savage pearls. Most likely they can be found in the ziggurat and that's where the group is headed next, but not before they have to recover from the fight they just had.
At least most of the group has gained a level down here so they had accomplished the goal that was set out before them.
Now if they can make it back to the surface before the water rushes in... Good luck with that...

Through the Curtain We Go

Well the group has traveled further down into the darkness and have passed through a blue curtain that looks like water and have come across a small village of humanoids that eek out a meager living. The local leader tells them about the 'Lords of Dread' that now live in the city below that was the home of demon fish before the humans from above cast down the tear of a God that drove the waters away.
He asks the group if they wish to see one of these so called demon fish and the next day the group accompanies him through another passage and come into a large chamber. At the far end of the chamber they can see the blue curtain and on the other side, water and lots of it. On the floor in the middle of the room is a stone shaped fish like thing that is dozens of feet long. The headman invites them to put their heads against it. As they listen in amazement, they can hear things moving inside. Somehow this thing is still alive. What is it?
