PancakePrince's Lair

..This is the place, right? Poking at the old sundial, you accidentally trip a mechanism, and the sundial opens to reveal stairs down into a vast network of tunnels lit with gently glowing orbs of light, of course being spacious enough to accommodate even the largest dragons.
Small rooms branch off, and a few dragons actively roam the tunnels- it seems this is where those whose places are yet to be decided stay.
