Alternate timeline
In an alternate timeline, Thutmose married Erimem because she was popular among the military and Egyptian public. He also had twenty-nine other wives, including his favourite, Techvis, and his three favourite sons were also born by Techvis. Thutmose murdered Erimem by poisoning her wine so he could make Techvis his queen without incurring political wrath. (PROSE: Echoes)
