Hibernation Cave

""Sometimes dragons like to be in dark places. Since we're sure that you don't want an angry dragon on your hands we thought that it'd be wise to provide a dark place away from the prying eyes of visitors for some of your dragons. Of course, since visitors can't see them, these dragons will not earn any income while hibernating!""
