Ketar Nor was a Neimoidian male, belonging to the Neimoidian Royal Guard, and his partner was Ruug Quarnom. In the wake of the Cadesura district bombing, Nor, along with Quarnom, journeyed to the city of Zarra, located on Cato Neimoidian. The Dark Acolyte Asajj Ventress's arrival on Cato Neimoidia led her to exploit his rage over the bombing and his already present animosity towards the Galactic Republic, thus radicalizing the young Neimoidian.
