In large human families, sons of concubines did not have the right to inherit the power and wealth of the family. Nevertheless, if a son of a concubine was cruel and fierce enough to kill his brothers and father, awe all family elders, and earn the support of all family warriors, even as a son of a concubine, he could take over the entire family for sure.
