Although Korsin was Seelah ' s only daughter , Korsin ' s mother only saw her as a genealogical detail and actively tried to restrict Korsin ' s training in the Sith ways , while grooming Jariad as the future Grand Lord . In what was ostensibly a gesture of Sith trust in the Keshiri natives , the young Nida Korsin was boarded in one village after another with a series of Keshiri nurse - maids and tutors , preventing her from receiving anything more than rudimentary training in the dark side of the Force . However , Yaru found a way around Seelah ' s machinations . The Grand Lord staged the deaths of several loyal subordinates who taught Korsin in secret during the night .
