"You will attempt to erase the debt if you give me books, and if this fails for some reason attempt to immediately arrange some other method of repayment?"

"Yes."

"Sure, you can give me books."

"Cool. - Cecelia, what year is it?"

"The year of our lord 1032."

"Okay. Limiting ourselves to dead people - "

Can she actually conjure things outside her demiplane? Full copy of the Old Testament in Hebrew?

Apparently she cannot conjure things outside her demiplane.

That's fair. Luckily time will be paused if she leaves here, so it's not very much trouble to go back to her demiplane, conjure it there, and then bring it back. She does that.

He accepts his book!

And she erases the debt. 

"I could do more, but I should probably look at a list of ancient literature first. I don't want to, like, get you entangled with people who haven't been born yet, or something, I can only erase debt to me personally."

"This will do! Thank you."

"You're very welcome." She turns to Cecelia and her fairy. "Do you guys want to go back to the demiplane now?"

"All right."

"We should probably bring the children, if this isn't Rana's court anymore."

"Sure. - I think I wanna test something."

She brings them back to her demiplane. 

"How many kids with the fairies?"

"Two. The two youngest."

And she brings Cecelia's two youngest kids to her demiplane. 

"Did you want the others, too? You had more, right?"

"I think - I might want a little time to prepare for that."

"Okay. Did you need anything else right now?"

"I don't think so?" She turns to Rana.

"Is there anywhere it's safe for us to go that has - plants -"

" - hm. I can try making more plants here, and if that doesn't work I think I'm okay with the two of you hanging out by our fairy circle at home? As long as you don't talk to anybody. Which I guess will be easy since you don't speak the language."

"That sounds good."

Can she make another tree? Maybe a pear tree this time?

Yep!
