Nusair was one of Caldane, Lord Caineron's sons. He is Donkerri's father; however, Donkerri's mother died bearing him, blacklisting Nusair for future contracts for children. Nusair attempted to kill Torisen multiple times, probably on his father's orders, including by pulling a building down on him at Tiglon and putting an adder in Torisen's boot at Mensar. Caldane considered Nusair expendable after Donkerri, telling him that he had neither "the courage to fight or the intelligence to intrigue", that he could no longer even provide him with grandchildren, and that the most useful thing he could do short of killing Torisen is letting Torisen kill him, to give Caldane a blood feud he could use.
