I don’t think who was in who’s spots was really thought of for the Rook AU, aside from Rook being in Frisks spot, and Rin being Toriel/Asgore– -Ana did a few drabbles on it, it was p. cool

I just know that it was something like Kai realized they were getting worse, and somehow managed to grant some non-corruptive power to Rin so she could protect the rest of the inhabitants from them.

When Rook fell, Kai took the form of a flower (cat’s possible too, but seemed flower mainly)

offf course though in knowing who Rook’s father was since I assume before all of that happened Kachessa told them…. they’d wind up using it to kind of tempt Rook, since it’s likely the demon side of Rook would be reacting to the corruption in the area or somethin’

but I don’t think who everyone else would be was decided at all? Hmmm.

tbh Rin as an undertale AU protag isn’t totally connected to an AU, though a possibility was thought of before. Still though

Rook(poisonedpedigree), in the AU with Kai in Flowey’s place (or, being a flower anyway… bad flower.)

mRin of course.

And Mint(askastagehand)!

I’m so sorry, Rook.

I DUNNO I was listening to that The Call song with that lyric comic for undertale and watched someone play the true pacifist end and thought of the AU and…

idek maybe kai went into sleep mode after he was himself again. really I just also wanted to draw small kai with rook
