Belir Noyan is initially a vassal in the Khergit Khanate under the rule of Sanjar Khan. He is also the lord of Narra. You may fight him or have him side with you as you help Dustum Khan, the claimant and Sanjar's brother, gain control of the Khanate. He has gained a mild reputation due to his penchant for raiding villages, especially those of lords he does not like, even if it would require travelling across Calradia to do so.
