Lis Kaslan and other surviving colonists
Parts used for permanent dwellings
At the time of the Dowager's arrival at Tatooine, Mos Espa was small enough that the crew didn't notice it, and assuming that the planet was uninhabited they attempted to land, where a sandstorm wreaked havoc on the powers, displays, and guidance systems on the Queen, causing it to crash.
The only known crew member who survived was Captain Lis Kaslan. He and the other survivors—the original "colonists"—built their first city, Eisley, out of the wreckage, while others who left went to found Bestine Settlement. The original inhabitants of Tatooine later renamed the city "Mos Eisley" to coincide with Mos Espa.
The city of Mos Eisley grew up around the wreck. As buildings were constructed, the ship remained in its place, standing nearly vertically in the sand. It was later made into a first-class hotel, because of both its novelty and location at the intersection of Dune Street and Inner Curved Street. The hotel became popular during conventions and trade shows that came to Tatooine.
