Jarl Turegor is initially a vassal of the Kingdom of Nords. You may fight him or have him side with you as you help Lethwin Far-Seeker, the corresponding claimant, overthrow King Ragnar and gain control of the kingdom. He is unusual among Nordic lords in that he wears the armor of a Swadian count, complete with a black Coat of Plates and a Winged Great Helmet.
