The throne name of a king who ruled briefly after Akhenaten — whether before Tutankhamun or overlapping his first years is itself debated. The name is attested on objects later reused in Tutankhamun's tomb; the person behind it is one of Egyptology's genuine open questions — candidates include Nefertiti, Meritaten, and a royal daughter or sister otherwise unknown. Existence attested; identity disputed. The series' identification of her as a sister of Akhenaten is its own flagged reading, argued from the legitimacy of royal blood.
