Are there Habitant rules about rogue washing machines not being permitted in the library? Or is it that the darned things refuse to follow the rules? They ruin it for everybody when they’re petulant. Down with petulant rogue washers! (Our new battle cry?)
It isn't so much a matter of "rules", (which we, out of general principles, principally eschew), but one of usage patterns.
The Flying Castle Habitat contains as a central feature, the Castle. The Castle walls are about thirty feet thick in the walls around the courtyard. This is not defensive. That thickness is deceptive, because it conceals small rooms on either side of a narrow corridor.
It's like a nightmarish rendition of a highway motel, with each room having only a single full-size bed, a small eating area, and a ridiculously minimal wash space. It is Spartan to the degree that a monk would feel claustrophobic.
But these courtyard wall rooms were designed for visitors, students, workers and volunteers in the other enterprises going on in the Castle. Basically, they offer the merest space to rest your weary head, before trudging back to work in the kitchens, vegetable gardens, laundries, dairy, or in the various theaters and other entertainment venues. It's a workspace environment. Kind of a bunkhouse.
Not that these rooms are completely without creature comforts, though. They have a comfortably-sized monitor screen for TV-style entertainment programs, or for use as a computer monitor. The sound, in the small room, is adequate. A special feature is a delivery system, similar to having a dumbwaiter, which is connected to all parts of the Castle, for requesting items to be delivered, or sending out small packages. One can order pizza, complete meats, drinks in abundance, and real books or printed material. After the meal, leftovers and soiled dishes can be sent on their way using the same delivery device.
Laundry and shopping purchases can be dealt with the same way. For serious stay-at-homes, there's little reason to leave this cozy nest.
But outside of the courtyard walls, so much more abounds to attract the eye and interest!
The courtyard itself has songbirds fluttering among the shrubbery and fruit trees, fountains and garden paths, and of course it leads into the Castle itself, with its large banquet halls, grand staircases and libraries, kitchens and bars, theaters and music rooms, swimming pools, a grand library which is roofed over with an atrium greenhouse cum aviary, and so much more!
Or one could go through the courtyard gate, over the drawbridge and moat, and out into the verdant pastureland that leads up to the forest line in the distance.
The canopy above, with artificial lights blurring the outlines of the structural members, gives the illusion of open sky. A close look even shows that a wispy condensation almost resembles clouds in the apparently open sky.
Or you can stay in your room and read.
Most rogue appliances are kept in the Lower Levels, where the dwarfs, and zombies carry out their work. The dust bunnies and the basilisk are one level below that. The walls and doors down there tend to shift, so please, don’t go down there without a guide. One with a map and a whip.
The Library is fairly high in the castle, and there used to be a Widow’s Walk where a certain piper could do his piping. That is seldom used, now, except for an occasional melancholy person or two.
