It's a huge spoiler but there is a translation thread on twt where a person has dedicatedly translated all hieroglyphics from whenever they appeared nl apparently theres some plot with past lives of isis Osiris Seth n nepthyis along with horus who's holding eye of ra in his hand in murals and is killed by Seth in a cave n Seth devastated runs away, is comforted by nephyths and called murderer by isis there's some theories that Seth n horus had a thing going on cuz there were mentions of taboo in the walls... so this is what we know so far. The plot thickens deliciously and I'm super hyped for more
Here is the link to a comment I said about it. In the comments under "here you go!" I put the links to the threads.

A VERY COOL FACT ABOUT ENNEAD IS THE MURALS AND HIEROGLYPHICS ARE LITERAL SPOILERS OF THE PLOT N NOT RANDOM BACKGROUND DRAWINGS THE AUTHOR MADE. THEYRE LIKE EASTER EGGS IF SOMEONE KNOWS HOW TO TRANSLATE THEM. THESE MURALS BEEN OUT SINCE S1 IN RANDOM CHAPTERS THEY TELL A LOT OF SPOILERS ABOUT HORUS THE ELDER AND PAST LIVES
