Area 54 is an isolated facility in the Nevada desert belonging to the autonomous agency E.R.T.D..
On its exterior, Area 54 appears to be a private airstrip., but its three 'hangars' actually conceal a research installation that goes down many levels.
Area 54 was active between the 1950s and 2003, when E.R.T.D. was shut down.
