Mos Espa is one of few port cities on Tatooine. Domed buildings protect the citizens against the glare of the twin suns and the scorching heat. Among the dwellings, workspaces, and commercial operations of many bizarre kinds there are also entertainment areas, including some of colossal scale. The famed Mos Espa Grand Arena can hold an audience almost as large as the city's entire population. In the time of the Republic, slavery persisted in Mos Espa, though the despicable trade was outlawed elsewhere. The true powers in control of Mos Espa were the Hutt gangsters, who found slavery a useful institution.
A harsh desert world orbiting twin suns in the galaxy’s Outer Rim, Tatooine is a lawless place ruled by Hutt gangsters. Many settlers scratch out a living on moisture farms, while spaceport cities such as Mos Eisley and Mos Espa serve as home base for smugglers, criminals, and other rogues. Tatooine’s many dangers include sandstorms, bands of savage Tusken Raiders, and carnivorous krayt dragons. The planet is also known for its dangerous Podraces, rampant gambling, and legalized slavery. Anakin Skywalker and Luke Skywalker both grew up on Tatooine, and Obi-Wan Kenobi spent years in hiding on this desolate world.
Discovered as a slave on Tatooine by Qui-Gon Jinn and Obi-Wan Kenobi, Anakin Skywalker had the potential to become one of the most powerful Jedi ever, and was believed by some to be the prophesied Chosen One who would bring balance to the Force. A hero of the Clone Wars, Anakin was caring and compassionate, but also had a fear of loss that would prove to be his downfall.
Watto was a Toydarian junk dealer in Mos Espa who bought Shmi Skywalker and her son Anakin from Gardulla the Hutt. An inveterate gambler, he sponsored Anakin in several Podraces, but often bet against his own slave, who was talented but inexperienced. Watto lost Anakin to Qui-Gon Jinn in a wager on the Boonta Eve race. Years later, he sold Shmi to the moisture farmer Cliegg Lars.
The mother of Anakin Skywalker was also a brave and resilient woman who survived life as a slave to become a Tatooine moisture farmer. Shmi surrendered her son to the Jedi Order, putting him on a path to become one of the greatest Jedi. Her death at the hands of Tusken Raiders became a critical step on Anakin's journey to the dark side.
