Slave Quarters Row, commonly known as the Mos Espa Slave Quarters was a crowded section of Mos Espa on Tatooine. Slave Quarters Row was situated on the outskirts of the spaceport, and was one of Mos Espa's poorest areas. The row was lined with cheap hovels originally built by the mining companies who first colonized Tatooine. These hovels were home to slaves of such prominent Mos Espa figures as Gardulla the Elder and the junk-dealer Watto. The hovels used outdated bio-converter power generators that converted sludge from the underground pipelines into natchgas to fuel the hovels' limited power needs.
