The Old Skull Inn

Some whisper of an inn that sails the skies on a dragon’s back. Bound to the mercurial archfey of the Court of Stars, this enchanted skyhouse glides through the planes on an endless, fate-smitten journey. It is said that those who earn the favor of the fey can call upon its services by chanting the dragon’s name, and journey aboard the skyhouse to any destination they please.
