Following the Huk War, the Yam'rii desecrated the burial grounds of the Kaleesh there, prompting Grievous to return from working for the InterGalactic Banking Clan to again lead the kolkpravis. The InterGalactic Banking Clan sabotaged Grievous's shuttle, the Martyr, nearly killing him and killing seven of the eight Izvoshra, elite warriors who protected him and carried out his will. The sole surviving Izvoshra, a tyrant of Kalee's western hemisphere named Bentilais san Sk'ar, rallied the kolkpravis and led the slaughter of the Yam'rii on Oben, where he subsequently moved his people.
Following the end of the Clone Wars and the establishment of the Galactic Empire, Captain Thrawn was tasked with pacification of the fringe of the known galaxy, and was forced to raze Oben. Sk'ar left to join the Empire, and the kolkpravis was taken over by a female Kaleesh believed to be the second coming of Grievous's dead soulmate, Ronderu lij Kummar.
