The Zssik Clan was a Trandoshan slaving family that operated out of the Wookiee homeworld of Kashyyyk during the Galactic Civil War. They bristled under the control of the dominant Blackscale Clan's organization, and plotted to seize power in a series of meticulously-planned operations designed to undermine the Blackscales and make them appear incompetent in the eyes of the Galactic Empire, even going so far as to provide the Wookiee resistance with the access codes for the Avatar Orbital Platform.
