First appears in: The Metal Wood
Sleeproom One is a "private Den room" used for clandestine meetings and rest. Megan (Phoenix) provided the room its numerical designation after being ushered there through a "thin door... cut right out of the thick cement wall". The interior is described as having a "plush black couch" and "shiny purple wallpaper" with a "vaguely floral pattern" that Megan found "relaxing, in an awfully stupid way". This room served as a sanctuary where Megan and Eric (Quynn) hid from Den guards and discussed the impact of the "Clean Up the Streets Act" and the loss of the city's metalwood supply.
