Biography
Xivu Arath is the sister of Savathun and Oryx. Being in the circle of power like Oryx and Savathun she is very powerful.

She invaded and destroyed the Cabal home world of Torobatl thanks to the betrayal of Empress Caiatl's close ally, Umun'arath. Umun’arath’s death at the hands of Caiatl accidentally completed a ritual set in motion by Savathûn, resulting in an invasion of Torobatl by Xivu Arath’s forces. The resultant destruction forced the Cabal to flee in a mass exodus with Xivu Arath in pursuit.
