AngelofSaverem's Hibernal Den

You wander into a large hollow carved into one of the cliff sides, it seemed to be naturally formed but had been dug out more farther in. The hollow is filled with flora and sleeping dragons, large willow trees act as cover from the light shining in from the hole in the ceiling. How did they get so many trees in here? How are they alive? You have many question to ask, but the snuffling of a sleeping dragon makes you remember the old saying.
