Leareth is watching her intently. 

"How long do you think it would take for an intelligent mortal to learn sorcery well enough to do that?" he asks her. 

"If they're as smart as me and were aiming specifically at this a couple years I guess?"

Leareth looks both relieved and faintly disappointed. "Then - people will still die, I think, while we are scaling up. I do not think we can cover the whole continent with you alone - just logistically speaking that is not feasible. But perhaps not for too many years." There's a distant, hard-to-read look in his eyes. 

"Yeah. And I don't think I can do anything about accidents if there's not an uninjured healer handy."

"How long do you think humans would need to learn the healing-sorcery that you were doing before?" 

"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."
