District 1 was the lowest of the fifty-two districts—vertically-stacked levels—of the Spire, the capital city of the planet Zakuul and its Eternal Empire. District 1 was built atop the Old World, also known as Oldtown, which was the first city built by Emperor Valkorion. Like all districts of the Spire, District 1 featured living conditions identical to the other districts, including numerous museums, restaurants, and entertainment complexes, though many residents of the Spire looked down on District 1 as part of the slums due to its closeness to the Old World.
