Serroco

Serroco was a planet inhabited by humans, and the site of a major campaign during the Mandalorian Wars, in which the Stereb cities were turned into glass craters by Mandalorian nuclear weapons. Displaced veterans from the Serroco campaign became the Serroco gang on Nar Shaddaa. During the Jedi Civil War, First Patriarch Lelin-Dor was assassinated by Revan, who considered him a destabilizing influence.

Behind the scenes
Serrocoans seem to have Asian characteristics when compared to Earth standards. As of yet, They aren't evolved enough to know if these characteristics are peculiar to that planet.
