Ranni!Reader (R!R) thoughts and brainrots: (cw R!R uses gender neutral pronouns but feminine honorifics, Traveler Lumine and Abyss Prince Aether, no Y/N because it's immersion breaking for me, sorry!)
- Thinking about it, golden blood doesn't make sense for for R!R. Canon Ranni is the antithesis of the Golden Order. Blood that sparkles with stars and swirling galaxies is much more fitting.
- Sumeru and Snezhnaya, the only nations who didn't participate in the hunt, close their borders and refuse to let anyone in or out. R!R is secretly meeting with the Dendro and Cryo Archons, to learn about their predecessor from Irminsul and make 'plans' with the Fatui.
- A fake Creator was on the throne when R!R descends? The fake had so many 'imposters' put to death that she didn't even bother to attend R!R's disastrous execution. When the surviving Archons went to confront the fake Creator, she was mysteriously afflicted with Deathblight. The Archons didn't mourn her, only the possible chance for atonement by executing her themselves.
- Teyvat possesses knowledge of R!R's life, like their parents meeting on the battlefield, Radagon leaving Rennala for Marika, the existence of their shadow Blaidde, R!R's demigod step-family and the fate of their siblings. It's... invasive and disconcerting all in one, but it helps to convince R!R that they are, in fact, connected to this world in some way.
- R!R being in their original body once more when waking up in Teyvat, and post-execution occupying a doll body that's even better and more life-like than their old one. Their ghostly face, like their blood, is made up of stars and galaxies. R!R makes Sandrone's entire year when they compliment her abilities.
- R!R calling Dottore 'Seluvis' and Childe 'Blaidde' by complete accident, and refusing to explain.
- R!R being an excellent artist! Drawing Omens and Misbegotten from memory for a curious Dottore. Explaining the history of the Golden Order, the Shattering, the House of Caria, and the nonsense that is Radagon and Marika somehow being the same person.
- R!R can't stand being called 'Your Grace.' It reminds them too much of Queen Marika and the Golden Order they sought to defy. As far as they're concerned, they're a Lunar Princess first and the Creator second. Either call them 'Lady Ranni' or don't address them at all.
- R!R's first followers in Teyvat are the Misbegotten Hilichurls from the Eclipse Tribe! They somehow understand R!R, and R!R can kinda understand them? After Teyvat's Night of Black Knives, Lumine introduces them to Ella Musk. Once R!R can fully understand the Hilichurls, they become R!R's intel network across Teyvat - they even paint simple Carian Crests on their masks and weapons.
And Ella's mind is blown because the Creator themself acknowledges her work? And wants to learn from her?? And she can freely practice with Hilichurls that aren't a danger to her??? Truly, she's brought honor to the Musk name.
- Blaidde! He's here because he's R!R's shadow. Teyvat knows some things about R!R, but they mistakenly interpret Blaidde as R!R's mortal enemy. The Archons don't realize R!R is alive in their doll body, and capture Blaidde to execute him in the Creator's name. R!R shows up, throws several Dark Moons in their faces, and rescues their sibling.
R!R: Was mine own death not enough for ye? Thou must taketh mine brother as well?
Archons: *surprised Pikachu face*
Then they both leave, and the Archons are in shambles because they've betrayed their Creator again.
- Blaidde becoming sort of friends/sparring buddies with Childe and/or Capitano. Dottore being fascinated by this 'Half-Wolf' and being forbidden from trying anything by no less than two separate gods (R!R and Tsaritsa).
- Xiao comes to apologize for his part in the hunt, expecting no forgiveness, and R!R doesn't give him any... because in R!R's opinion, the fault lies with Morax, who used him as a weapon. R!R has an unfavorable view of gods in general, and while they don't enjoy being the god of an unfamiliar world, they are willing to use that authority to declare every one of Morax’s contracts null and void, not just his contract with Xiao.
Zhongli feels the change, in some way, and his heart sinks in despair.
- Spirit Calling! R!R fashions a Spirit Calling Bell. There are no Rebirth Monuments or Spirit Ashes in Teyvat, but given what they've learned from Nahida, the Ley Lines might serve a similar purpose. R!R brings Xiao to the Guili Plains, briefs him on the plan, and has him ring the bell as a test. The four deceased Yakshas are summoned, masked and armed, awaiting orders.
Remember the sidequest with Aurellia the Spirit Jellyfish, where you reunite her with her sister?
In the end R!R let's Xiao keep the Spirit Calling Bell, not only as a reward for his help, but to further foster his goodwill towards them, and to make him stronger for the coming battle against the heavens.
- R!R teaching non-Vision holders how to use magics from the Lands Between. Teaching Childe thorn sorceries. Infusing the Abyss Prince's golden sword with R!R's fragment of Destined Death, and gifting Lumine with the Godslaying Blackflame Ashes of War. Crafting a makeshift seal and teaching Pantalone 'Catch Flame' just for funsies. Teaching Aether and Lumine to cast gravity sorceries, or Elden Stars and Founding Rain of Stars - because the idea of star-children raining destructive stars down on Celestia is amusing to R!R.
Not much I can say in addition, honestly! Although, I can propose one thing: what weapons would be given to those Ranni! Reader is alright with?
Also Blaidd my man 😭 too soon buddy too soon
