Etran Harborage (Earth-5875)

Etran Harborage, also known as Trove, also known as Shield World 0459, was a shield world created by the forerunners, in the Korinth Prior system. Its original intention was to safeguard the species of the Milky Way galaxy from the xenomorphs and the effects of the Halo Array. It was home to the Apex Site, an installation that housed a buried fleet of Sojourner-class dreadnoughts.
