The Cluster

A nickname commonly used to refer to the Milky Way, Triangulum and Andromeda galaxies collectively, as these are the only three galaxies known to have given rise to major civilizations within the Local Group. It was mostly coined by the Coalition of Intelligent Organisms following the start of the Second Cluster War, though it was not uncommon for other alien races to refer to this triumvirate of galaxies with their own special names during the height of their respective civilizations.
