The party makes their way back up the hill giving the Dragon's bones a wide berth. At the threshold of the cave you pause and light a torch and give it to Rik. He gulps but takes up his duty as torchbearer. "Umm if I die please make sure my wife is provided for."
With out any further drama the party enters, the cavern slopes downward almost at once, the grade is a good 5-6% and travels hundreds of feet. Along the way you notice lots of tracks just as you did at the entrance. Eventually the cavern opens up into a natural underground lake. The beach that you come out on is well used by animals and others for freshwater apparently.
As you stand along the beach you notice lights spring up in the deeper parts of the cavern. It is strange sight, the lake, the lights, the caverns....
