The Tsinimals were an alien species. In 129 BBY, they conquered the planet Langhesa and enslaved the native Langhesi because they saw their biotechnology as an abomination to their gods. This led to a mass migration of Langhesi to other parts of the galaxy.
However, piracy and war weren't opposed by their gods. The Tsinimals were described as "graceful and intolerant."
