The Back Spiral was the name given to the Tion Cluster planets situated in proximity to the Indrexu Spiral. It encompassed Kaon as well as other planets found along the path of the Tion Trade Route, for example, Caluula, Brigia, Eredenn Prime, Rudrig, Tion, and also Raxus Prime.
During the time of the Pre-Republic era, the Pirate King known as Xer VIII undertook a military campaign inside the Back Spiral from 25,150 BBY up to 25,130 BBY. He successfully seized control of numerous planets there, incorporating them into Xer's Empire.
