OOC: For any of you who have been snoozing, I think things are going to get really interesting now. If you don't start posting, your characters may be targeted first, if the storyline leans that way.
You follow to the left. The blue water turns an even brighter glowing blue, so bright that you do not even need lanterns or light sources because of its luminescence. You walk down the left bank as the current grows strong like a river as more water flows in from rills on your right as runoff.
The ground is slightly muddy and slopes down as you continue toward the source of where you heard the man's screams. The river then flows down about 10 feet into a large cavern filled with water.
As you approach from the south (as oriented on the map), the mud beneath your feet gives way to very slimy and slippery rock. The path is like a 5-10 foot wide bridge forming a rough plus (+) sign with ledges going right, left and forward before the forward path leads to a roughly 40x40 foot flat area. There are two small "islands" as shown in the map.
In the place marked X, though obscured by the pillars of rock, you see an old man with white hair laying spread-eagled on his back. He is on some sort of platform that seems to be just 6 inches to a foot underwater, so that the water nearly covers his body except his head. His hands are chained, and the chains extend around and have him shackled to a pillar on his left and on his right, with his legs chained to a spike driven into the outcropping of stone wall south of his feet.
Several channels of water drain into this area with heavy currents. The water in here is extremely torpid and has an undercurrent pulling toward the west (where it is marked "60 ft"). At that area is a 60 foot tall waterfall, and all the water seems to be draining in that direction. If you get pulled into the water anywhere in the room, you can imagine it will be a hard current pulling you under.
The currents in the room have also created so much steam and spray that you cannot see much beyond the center of the giant chamber because it is obscured and dark. (The area marked with a rough half circle in the northern half of the chamber shows where you cannot see--fog of war.)
The noise of all the water rushing and draining in here is also so loud that it is hard to hear. That is perhaps why the thing perched in the center of the platform area straight ahead of you still seems to be slumbering.
Yes, a dragon lays curled in the center of the squarish platform area that is directly in front of you. Its eyes are closed and it appears to be unaware that you are present. It is a luminescent blue, but almost translucent in places. From head to toe, it is probably 50 feet long.
The water here is bright blue, and you believe it may be the healing water discovered previously. Now...to just find the bushes of berries.
