The Agency's yard and the alien abductions
South of the Agency's garden stand four hangars, one for each visiting people, each holding one of their small craft under study by scientists in white coats. The shutter doors open and close only for Game Masters and Community Moderators (a button by each door), so staff can show visitors in. Beyond them four great gauze tents shelter the motherships of the Tall Ones, the Collectors, the Observers and the Warren, with scientists and soldiers working round them. Scientists greet staff ("Good day, sir"), soldiers (and the Agency's patrols out in the world) salute staff until they move on.
The Agency's cells hold a different visitor each; Interrogation Room B, behind the one-way mirror of the interview room, holds another chained to the table.
Being taken. A rare landing party may snatch a captain (staff can arrange one for any of the fourteen peoples). The first time a people takes you, you wake groggy on an operating table; when your head clears there is a chest at the foot of it: 1,000,000 gold, a letter and a polaroid of the visitors posing round you, plus a unique achievement for that people (once each). The BTH Police take captains differently: they run in, throw you with a judo hip throw, hold you kneeling, and the black bag is pulled slowly down over your head while the light fades.
