Guys- repost bc i didnt like the 2x speed thing 😓 also reply to this comment which archon they should react to first! (Update not taking votes lots of ppl suggest going with venti, and i agree so ill probably just go in order of the archons the traveler meets)
Tsaritsa(or Buer) gathered the archons to fight the Heavenly Principles in a last ditch effort to revolt(The First Ubuyashiki or smth) but Celestia gathered the cursed K'hanrians and made them even more hostile against everything. In a last effort, Mavuika gathered her remaining divinity to curse the K'hanrians to burn in the day, while the rest passed down their elements to humans(since Celestia doesn't give out visions anymore due to the archons' revolt), which over time, became breathing instead(let's say that Venti used his own remaining divinity to spread the archons' diluted powers in the wind, and only trained and skilled individuals can draw from that small piece of divinity).
As for demons, other than the archons, no one knows that they're K'hanrians, the ones that know about demons only know the part of the story that they were once human, turned monsters. Muzan was one of the last K'hanrians, who maintained a part of his consciousness and used it to gather demons under his wingas the demon king. His original goal was to kill the archons and the Heavenly Principles, but due to Celestia's doing, he's now after the extinction of the human race, and aims to find thr blue spider lily that helps him become immune to the sun(a plant made of the mixed divinity of Tsaritsa and Buer, since Ice or Cryo can soothe or nullify burns. And I didn't say Hydro because let's say that the archons' revolt was after Furina's Archon quest, so Focalors is dead. The hydro divinity is with Neuvilette, but he refused to hand it over to the archons; training humans himself and passing his divinity to them, which mixed with Venti's element that helped Water Breathing live for so long)
PLEASE START BY FURINA (i love how they think she got beheaded, but you could make it that she didn't get beheaded by demons, instead by the corps itself after being accused of betraying, it would be SHOCKING)
