Mass Effect: After Armageddon
Luna is Earth's moon, located in the Sol System. It is home to Systems Alliance research stations, colony housing for veterans of the Reaper War, and one of the finest medical facilities in the galaxy. It once housed a bustling economy which is now in a recession. Security is tight, so there is little crime.
Though Luna is Systems Alliance territory, there are also embassies for the Asari Republics, Turian Hierarchy, Salarian Union, Krannt of Clans, Republic of Rannoch, and volus, elcor, and hanar governments. The Citadel Council has an office near the other embassies.
