Kadorr was a devious individual with great ambition. He hated people who did not give him the correct respect and wanted revenge for also the minor slights. Also, Kadorr became infatuated by Ashemmi and was insanely jealous of both Sememmon and Dag Zoreth.
Kadorr was the star pupil of Ashemmi for his magic ability and his ruthlessness. Many at Darkhold ignored him, thinking he was a teacher's pet but Kadorr took names of all of those people for future revenge.
