Courtyard

The courtyard, sometimes referred to as the Miss Cam Courtyard, is a unique location in the middle of Headquarters that provides relief from the stark, enclosed corridors. It is not widely known, but people known to visit it regularly include the Marquis de Sod and the Sunflower Official, Agent Ilraen-Aroline-Fothergill, and Alice, who actually lives there with a herd of other equines rescued by various agents over the years. It has at least once been a battlefield, during the invasion of the Black Cats.

The courtyard is large enough for a small herd of horses to live comfortably and contains a few footpaths and scattered benches and trees. It is grassy, and presumably it has some sort of water source, though this is not documented. It also has a sky, though whether it's really open to the outdoors somewhere or if it's something like the ceiling in Hogwarts' great hall is unknown.
