For my third fantasy book, I decided to add a biblical theme that involves two feuding brothers. One brother is the ruling emperor and the other is the spare heir. One brother has three wives and the other has one nearly catatonic wife. One brother has 18 children and the other has three deformed stillborn children. One brother is handsome while the other has a scarred face, a dead eye, broken nose, and a spinal injury that causes him to walk in a crooked fashion. One brother will be charismatic and generous while the other will be power-hungry and bad tempered. Overall, all of these differences will eventually culminate in a feud between these two brothers for the imperial throne.
