The Czerka Corporation is a galaxy-spanning megacorporation that controls interests of a countless number of planets.
The Czerka Corporation, also because of the fact that they were often working with the Sith during the Jedi Civil War and supplying them with armies in exchange for exclusive trade rights on the conquered planets, have a generally bad reputation and are considered extremely unethical and opportunist.
One of the most notable enterprises was the one on the Wookiee planet Kashyyyk, which turned many Wookies into slaves. Slavery, although illegal, was made possible because of some legal loopholes concerning the planet's location. It was ultimately ended by a revolt instigated by Revan himself.
