Nuyukh was a character in Mount&Blade version .202, aka Warrider. He appears as a minor antagonist during the main questline.
Barthai Khan referred to him as a 'rabid dog', and accused him of stealing his cattle, attacking his camp, and finally, kidnapping Uruzuge. Indeed, Nuyukh kidnapped Uruzuge, and later, when the player character caught up to him, explained that he did so on Akhad Thell's behalf, because the latter promised to make him 'the Great Khan in the East'. He regarded the player as an annoyance, but held Akhad Thell in high regard because of his magics.
Refusing to surrender Uruzuge to the player, he chose to fight for her, and died in battle. With his last breath he called out to his ancestors, saying that the Black Wolf was coming to take him to them.
