A secluded landing platform somewhere in the Undercity. Technically, the Undercity is any section of an imperial metropolis devoted to maintenance, utilities, and other vital, but not necessarily residential or commercial needs.

Undercities are named as such because they tend to be built underneath large platforms upon which the rest of the city exists. Where possible, Undercities are sunken into the crust of the planet, but due to planning needed for excavations on such a large scale, the cities tend to be built sandwich/plate like on the surface of the various habitual worlds.
