"Almost as much time but with about the same curriculum, won't slow them down much."

Nod. "And what kind of teaching is this timeline premised on? Self-study, or tutoring from you or a skilled teacher, or some teacher feedback but mostly practice..." 

"Books like I had and focusing on it instead of also needing to forage and make their own clothes and stuff, plus some occasional asking questions of me. So I'd need to go get a book. I won't have to copy them all out if I can trade them, is there anything reasonably - innocuous -"

"Probably not here at this library, but I am sure I can obtain you some very innocuous books of childrens' stories and ballads and such, if fairies would like those." 

"Libraries aren't picky. If they don't have it they'll want it."

"I will work on obtaining that for you, then. How many do you want to trade?" 

"Well, do you want anything besides sorcery books?"

"What other topics do they have?" 

"...lots of things? Like your library does?"

"If you can get me a list of titles, I can go through and see if there are others I am interested in trading for." 

"That would also take a long time but I guess it's probably worth doing."

"It does not need to be right away. You can trade for the sorcery books first, I can provide a number of trade-books appropriate for that, and then figure out more later." 

"I can only carry so many anyway."

"Fair enough. Well, I can try to obtain fifty innocuous books to trade, which should cover a few trips." 

"This will make the library fairies very curious about me, unfortunately, so I think we should make sure that Sunspring can in fact clear my orders by Mindspeech and that I can't order her if she's not trying to listen."

"Right. I suppose she can give you a temporary verbal order and then try to rescind it with Mindspeech from a distance - is there any reason to think it might behave differently if she were rescinding an order given by someone else -?" 

"No, that should be identical."

"All right, so she can test it herself without needing a second person. She can also see orders with Mindhealing Sight, which does not involve reading actual thoughts, with your permission she could use that to check from ten yards away or so each time before you come back through the Gate." 

"That's a good idea, someone really smart could make me come through with my ears put out."

"And possibly use sorcery to disable your ability to hear Mindspeech, though that would be surprisingly clever. It seems worth being cautious, though."

"It would be a new technique, those take time to invent."

"Noted. I think I still prefer to be overly cautious, though." 

Leareth gets to work on collecting books for her. Twenty works of fiction, none containing the names of gods or real still-living humans, can be scrounged up from nearby sites in the north within a day. For the rest he'll need to make a request from the Order of Astera, which will take longer. 

She doesn't want to fly all the way to and fro with twenty books at once. She takes a bundle of ten, and flies out, and comes back.

Nayoki dismisses all orders via Mindspeech every few minutes, which should work according to their tests, and then when Promise is on her way back, holds up a hand and gets Promise to pause ten yards from the Gate and looks at her with Mindhealing Sight to check for any new orders before ushering her through. 

She's clear.
