The group makes their way carefully to the place where they fought the dragon. The smooth golden light from Eldath's fountain lights their way much better than the continual flames did, enabling them to see a good 40' ahead instead of 20'.
First, they go a bit south, then east along the way, then south again. They pass by a closed door and the corridor where Jalon and Ivellios met the ghost. There is a faint smell of burnt meat in the air, getting stronger as you go south. When they pass that way, the light from the vial turns white and dims a bit.
In the practice room with the training machine and training-themed frescoes, the secret door has been closed by someone since the group left. They quickly get it open again.
On the other side is the witches' bedroom. Some things are missing since last time (clothes on pegs in the walls, writing implements on the writing stand etc). Looks like whoever lived here didn't plan on coming back. The mosaic of strange glyphs still covers the floor.
Opening the door out of the room, the party exits into a wide, L-shaped hallway that is adorned with bas-relief depicting abstract, geometric shapes. This hallway is, like most of the dungeon, littered with organic and mineral debris. This is when Taz's light returns to a nice golden color.
They then go south and east to finally arrive at the place where they fought the dragon. It's body is still here and small flames still burn its flesh in places. The stench of burnt flesh is overpowering here.
Looking around, the party find themselves in another wide L-shaped hallway, debris-strewn and decorated with partially intact bas-reliefs depicting monks standing in line.
The two doors leading to the three rooms with the imp smell are closed. The rooms themselves have already been pretty thoroughly checked out by Ubaar last time. This was where you recovered the religious artifacts.
The two doors leading to the lizardfolk's room are open and no sign of movement is seen in there. There is also a door to the east that is closed and hasn't been explored so far, and a corridor leading north.
