Did I just softlock on the endless soul?

First play through. I refused her request cause i didn’t wanna piss off a god by not holding up my end of the deal. After some wandering around and resorting to googling it (which i wanted to avoid) it seems like i’m fucked, cause there’s not really any empty scrolls around and I’m playing Cahara. Do i have to reload like, 2-3 hours now?
