Rhye is a fantasy country in which some of the ban Queen's early songs were set (most notably Seven Seas of Rhye). The land of Rhye was originally made up by Freddie Mercury and his sister, Kashmira, when they were children. After joining Queen as an adult, Mercury wrote some songs about that country, including Seven Seas of Rhye, Lily of the Valley, My Fairy King, Ogre Battle, The Fairy Feller's Master-Stroke, and The March of the Black Queen.
