King's Galaxy
The King's Galaxxy, a supergiant elliptical galaxy, was first colonized in the 69th Century, and was formerly the seat of human civilization. King Haile Selassie II, King of the Universe, resided at Babylon Colony in the King's Galaxy from 6950 until 8808, when he moved his residence to Zion Colony in The Castle. The King's Galaxy sits at the hub of the Virgo Cluster, one of the richest concentrations of mass in the Laniakea Supercluster. It is the largest galaxy in the Virgo Cluster, and one of the largest in the nearby universe. It houses an enormous class 9 black hole, with a rating of 9.799, that serves as a strategic departure point for gravity drive travel throughout Laniakea.
The King's Galaxy houses many military and police installations, with entire colonies devoted to raising soldiers and patrol officers. Most of the galaxy still belongs to the Royal House, even though the seat of royal power has not been there for nearly two millennia. Several cosmopolitan intergalactic trade hubs are also located in the King's Galaxy, with major corporations taking advantage of the galaxy's massive black hole. No black hole of this magnitude has been found elsewhere in Laniakea, though some speculate there is one sequestered somewhere in The Castle, with all references to it redacted from public sources of information. The next-closest confirmed black holes with larger masses than that of the King's Galaxy both lie in the Coma Supercluster, nearly 100 Mpc across the Local Void. One lies in the Coma Cluster; the other lies in the Leo Cluster. The former is a class 10 black hole, and the latter is a larger class 9 black hole.
The King's Galaxy is likely a former quasar, and still contains enormous sources of radio wave output, as well as a relativistic jet extending from its active nucleus. Contrasted with the Sombrero Galaxy, another galaxy with an active nucleus, The King's Galaxy is more suitable for habitation simply by way of is enormity, such that the high luminosity of the galactic center does not disrupt cycles of day and night everywhere in the galaxy, and its nucleus's exotic radiation dissipates before reaching the vast majority of habitable systems. While the King's Galaxy is only about 50% larger than the Milky Way Galaxy in terms of radius, it has a spherical shape, making is vastly larger in total volume. It contains approximately three trillion stars, substantially more than the Milky Way, which houses some 400 billion stars, and the Andromeda Galaxy, which houses one trillion stars.
