Qadel

The Qadel were a sapient species of slavers. According to the Huttian play Evocar, which was written by the playwright Direus'Pei around 671 BBY, the species was driven into extinction by the Tionese warlord Xim. Upon his capture and subsequent trial by the Hutts, he justified his extermination of their species upon the basis of their having been slavers. This event occurred approximately between 25,130 and 25,100 BBY.

Quote from Play
Shool: "First and foremost, Xim, Son of Xer, you are charged with causing the extermination and extinction of nine sentient [sic] species." Xim: "Nine? I know I spaced more than that." Shool: "Among them the Qadel, the Ermi, the Veeza, and the Zoa'mon…" Xim: "Slavers all. I did the galaxy a favor." ― Rexrax Shool accuses Xim during his trial in the play Evocar''
