I think it could be Isis the successor. She's very powerful but was blindly in love with Osiris. Horus might have stolen the eye when he was born.
Btw one of the miths is that Isis deceived Ra by making they tell their true name which made her receive all the power and authority they had, and Isis become the new supreme ruler of Egypt.
Extra: after that Ra retired to only fight Apep and Seth joins as punishment after losing to Horus lol
