Williams Hall is one of the three First Academy residence halls on the campus of the United States Academy of Extranormal Studies (the other two being Boruszkowski Hall and Cocking Hall). Cadets who have civilian status (such as Tiffany Blum-Deckler), as well as cadets that are attending USAES at the request of other nations, spend their first year at Williams Hall before being assigned to other quarters, where they take a slate of special enhanced- inindoctrination and 'cultural awareness' classes to help them assimilate into life at USAES with a minimun of stress. Foreign students also attend special seminars on American culture (in order to avoid mistakes such as reacting to individuals according to the way that television and film depicts them).

Williams Hall has a gymnasium in the area occupied by a cafeteria in the Gilmore Hall and Swedlund Hall; Academy intermural sports appropriate for the venue (basketball, dodgeball, volleyball, etc.) are played here.
