The Return of Celadon
A short hike up from the village on a well-traveled logging trail leads to an area described on your map. Someone has been expecting you- for a side trail, slightly obscured by brush, has been cut through the brush.
You find yourself at the opening to a cavern in the side of a granite bluff.
(presumably the players will go in)
It’s pretty dark in here. (draw the front side of the shore). There appears to be a lake blocking the the passage in the cave.
(after the players swim/get across) On the shore you see three very large crocodiles lounging in front of two massive, dragon scale entryway doors.
