Slythor was a Squib crime lord and owner of the R4-series astromech droid R4-B11. He worked from a base on Korad during the height of the Galactic Civil War. He often considered himself the "High Exalted Ruler of Korad." Many people doubted that because nobody wanted to live on the junk-covered planet. He traveled around on the planet on the Peeve, which was a pleasure craft made from the ruins of an AT-AT Walker.
