from the introduction: D&D Skyships is a supplement to fifth edition Dungeons & Dragons set in a universe of ships that fly between the worlds and of battles in the air and in space. What you will not find here is a setting with descriptions of new worlds to explore, monsters to defeat and new races defined. What you will find here is a basic set of rules compatible with fifth Dungeons & Dragons 5E that will provide a foundation for adding flying ships or taking your D&D adventures into space.
