The Sinner's Identity From a New Perspective
Been a while since I posted here but with finals almost over I am excited to come back here to discuss lore and make conversations! I want to keep it simple and short because I arrive at the same answer I did before but with new reasoning.
edit: I don’t mean to suggest the Sinner is THE god of wisdom— rather a god of wisdom with control over the irminsul. Not taking Nahida or Rukkhadevata’s title. It is also possible the blessing can be given because of their power over the Irminsul and not bc of a title…
Nahida said someone is obfuscating the sibling's fate. She explained that there's another person who can control the Irminsul- and that she cannot determine the extent of their capabilities if they can override the Avatar of the Irminsul herself.
We also learn that Fate is connected to and stored in Irminsul.
About the One who obfuscates Fate
Chlothar's medicine for Caribert can only be made in Sumeru, this is because "this medicine is imbued with the power of Sumeru's God of Wisdom":
However, Sumeru had 3 Gods of Wisdom. One in particular was offered the gnosis before Rukkhadevata. The Gnosis symbolizes the title of the Dendro Archon and their mastery over the irminsul. If Deshret was the Heavenly Principles first choice, it makes sense to assume that Deshret had the ability to control Irminsul.
\"gift granted by the divine throne\" -> Gnosis
If the medicine needed the blessing of A God of Wisdom, and the one who gave it was not Nahida, then it makes sense to assume that the Sinner is a God of Wisdom, from Sumeru.
This connects to my original theory of Deshret's crystal looking just like the Sinner's crystal way back when we only had the Caribert trailer (good times- I miss the Dain quests): https://www.reddit.com/r/Genshin_Lore/comments/117vocy/something_i_noticed_in_the_new_35_trailer_may/?utm_source=share&utm_medium=web2x&context=3.
A note: to create the medicine they needed to mix Kalpalata Lotuses, Sumeru Roses, "special water", and the "strange mushroom" that grew from the mother's grave. Both Kalpalata Lotuses and Sumeru Roses aren't really lotuses or roses, they are misunderstood, or mischaracterized. This could be intentional- to allude to the sinner being mischaracterized, or the conflict in Khaenriah being misunderstood.
Counterpoints:
Maybe Chlothar was tricking the traveler/the sibling so there was no real medicine? (though I think Chlothar was actually trying to find a way to cure his son and wouldn't mess around with that kind of thing, not even to trick the traveler)
Maybe Deshret was offered a different gnosis (not the dendro one)?
Edit: the interpretation that Deshret is a god of wisdom is my interpretation and could be understood differently. it is fair to point out that GoF pursued wisdom in her own way, and it’s possible deshret pursued wisdom in his own way too.
