Assuming you all go through the door...
You push open the heavy copper doors, and step through into a large square room. Rock rubble is scattered across the floor, and the walls are covered with carvings showing a lizard or dragon-like god stepping forth from the walls of a temple, taking the gifts offered to him, and disappearing back into the stone. The lower part of the far wall is also covered with writing in a script unknown to most of you, although Jason and Seraphina recognise it as Draconic.
A strong musky smell lingers in this room, similar to the stench of the zombies that unsettled Kerrick's stomach. The constant sound of rushing water that has echoed in your ears since entering the mines has faded to the faintest whisper.
Three passageways lead out of this chamber (discounting the doorway to the south from which you entered), heading to the north, east and west.
