Luna is Earth's only moon. It was once the exclusive residence of the Selenite Hives until the Selenite Wars of 1889. The Selenites lost the War to Britain and the United Peoples of Earth. Luna was annexed as a British territory. Today Luna is the home of the Luna Planitia Ship Yards, famous for constructing the ships of the Royal Æther Fleet. Many other industries now exist in the old Selenite chambers under the surface. Mining, hydroponics, manufacturing and fuel refineries are spread underneath the barren lunar surface.
