so the true nephthys is in that dark cave? but what about the one with Isis? Omfg I should...

I can tell u but it's a spoiler. If u wish to u know lmk

suree I love spoilers

I'll try to elaborate onto this in bullet points!

1. There are two mirrors one for sekhmet one for hator. The two of them have different power abilities which I'm also not sure of/kinda forgot
The sekhmet one apparently traps ppl inside the mirror if the person whose face u see isn't the person u genuinely love.

Now the next part is a future spoiler so pls skip if u don't want it. But the reason nephythis is inside that mirror cuz during their harmonious reign Osiris got that mirror n placed it strategically so that it looked like offering tribute and wanted Seth to use it n see him so that og Seth would get trapped inside the mirror and the version outside will fall in love with Osiris or get brainwashed magically. But nephyths accidentally uses the mirror and sees Osiris in it. Now nephythis innermost desire was to have a child so that she can be more bonded down Seth who's alrdy her husband and in her trance a part of her heart gets trapped inside the mirror which we can say is the og nephyths n the one outside is the one that approached Osiris n struck a deal with him. She took his seed n bore anubis in exchange for granting Osiris the power of bringing life since male gods can't have kids but Osiris wanted to have a child with Seth because of twisted reasons you'll read in details in future chapters. But Osiris fails to create such a child using Seth's sperm so he plans to kill anubis n use his body as a vessel to host the child he plans to bring in this world. Seth pleads n begs against this n agrees to being raped by Osiris.

2. The other mirror is hators mirror n she gifted it to horus but he saw Seth in it n since he genuinely loved Seth he wasn't trapped in it but his darkest emotion n urges got amplified n he raped Seth against his wishes (like nephyths with Osiris)



Now to brief a bit on the theories in comment section

You see, the murals and hieroglyphics throughout ennead since chp1 till now aren't random drawings tye author made for background aesthetics but they're actually legit and readable and are literal spoilers for the plot. The murals that horus n nephythis are now reading is about themselves in their past lives or smth(not revealed yet)

a person on twt did a translation of the hieroglyphics and this Is what we know so far
1. The five siblings had horus as well as sixth sibling ( we call him horus the elder)

2. He n Seth had something going on (some theories suggest romantic involvement since there is a mention of taboo between them

3. For some reasons unexplained this past horus or horus the elder is murdered by Seth who devasted, runs away and is called murderer by isis n comforted by nephythys

4. Fan theories say that Osiris must've done something to make Seth kill horus after which isis must've collected his ashes and planted them in her womb and did magic to make everyone forget their past collectively

That's pretty much everything that's being discussed and I hope I was able to describe it properly

thank you for your perception and wonderful insights!!
So the og Nephthys was instead trapped in the mirror and not Seth? and what's up with everyone rapping Seth, like I get it it's in every mythology but that's so shit. Also it's possible that Horus and Seth have met before, but Isis erased their memory?
