Star Wars: Ashes of the Old Republic
Mos Eisley, formerly known as Eisley, was a large spaceport town on the planet Tatooine. It was the largest settlement on the planet and generally known as the “armpit of the galaxy”.
Mos Eisley was located in a valley somewhere to the southeast of the Jundland Wastes and roughly 80 kilometers north of Anchorhead, near the desert palace of Jabba the Hutt.
From a distance, the spaceport appeared as a haphazard collage of low-grade duracrete, stone, and plastoid structures that spread outward from a central power and water distribution plant. The city lacked a main landing facility; therefore it relied on 362 individual hangars. By order of the Empire, all of these hangars were equipped with time-lock devices. Illegally parked vessels were not an uncommon sight.
The town was really larger than it looked, as a good portion of it lay underground. In fact, it had a population of around 40 to 60 thousand people, varying seasonally.
