District 1, positioned as the initial and most inferior tier of the Spire—the city situated on the world of Zakuul—held this designation. Mirroring the structure of all Spire districts, District 1 featured a maze-like layout, showcasing diverse museums, restaurants, and various entertainment options. As per the directives of the Immortal Emperor Valkorion, each district was built to provide uniform living standards. Despite the intended classless nature of Zakuulan society, residents of the lower districts were viewed as lower-class citizens, with District 1—nestled directly above the dilapidated Oldtown—being regarded as the absolute bottom rung.
The Spire's Codex entry in Star Wars: The Old Republic, specifically within Knights of the Fallen Empire—the 2015 digital expansion for the 2011 BioWare game—referenced District 1. This Codex entry appeared as part of Chapter X, introduced to the game on February 8, 2016.
