You're right the 3 aspects of ra have been mentioned here as well thru the mural inscriptions which were translated by fans on twitter.. for years we have been theorising the arrival of atum and it it'd be a male form since khepri as dawn has been depicted as a child. There were some speculations about horus absorbing Ra to become Ra horakhty or Ra planning to absorb horus inorder to regain wadjet back but I never once thought about the atum horus angle wow. Could u elaborate more about it if u dont mind? Sekhmet n hathor in this manhwa share the same body but diff life force so it has me wondering if indeed instd of a ra horakhty mojito might take this atum ra path.
So Kane Chronicles fans know that there are the three aspects of Ra: Ra, Khepi, and Atum. I wonder if this version reinterprets Atum as the one who possesses the eye of the Sun, so in this case the trio would be Ra, Khepi, and this “Atum-Horus”.
Kinda like how Hathor-Sekhmet are often seen as the same deity, i really have to say, this author really love Egyptian mythology cause wow.
