The Star Kingdom of Manticore is the star nation that occupies the Manticore binary star system, a monarchy. The current ruler is Queen Elizabeth III of the House of Winton. The binary Manticore System was located 512 light-years to the Galactic north of the Sol System and Earth. It contained three habitable planets: Gryphon, Sphinx, and the capital planet Manticore.On Basilisk Station (Harrington 1), David Weber, 1993 The Star Kingdom was a single-system nation. From the 19th Century Post Diaspora (when humans left the Sol System) onwards it began to incorporate new systems for strategic reasons, mostly to control the termini of the Manticore Wormhole Junction and the possibility of war with The People's Republic of Haven.Ashes of Victory (Harrington 9), David Weber, 2000Crown of Slaves, David Weber, 2003
