District 36 was one of the fifty-two districts—vertically-stacked levels—of the Spire, the capital city of the planet Zakuul and its Eternal Empire. Like all districts of the Spire, District 36 featured living conditions identical to the other districts, including numerous museums, restaurants, and entertainment complexes. The anarchist and bomber known as Firebrand destroyed the District 36 Museum of Art shortly after arriving at the Spire, earning her a reputation as a dangerous and fashionable terrorist.
