And here is the "supplies for visiting humans" room.

It contains so many supplies! She stands still and looks at them.

"Take whatever you want, within reason. If there's anything you don't know what it is, feel free to ask."

She nods absently, gazing at the things. There are many things. (It's easier to inspect their reflections than the things themselves.)

Well, if she's going to be doing that, Kanimir studies the quartz crystals some more.

Eventually she goes around and collects some objects which she bundles up carefully to take back to her room.

"If you are hungry or wish to freshen up now, I'll leave you to that. Otherwise, I should probably show you which sections of the library are off-limits sooner rather than later."

"I can look at the library now," she says.

Alright. Back to the library!

The sections she's not permitted to access are mostly contiguous, but there's a bookshelf she's allowed in the middle of them. She isn't forbidden from entering the restricted areas, just reading from them.

She looks around and takes careful note of which shelves are and are not allowed, then nods. "Okay, I'll remember."

It shouldn't be hard--there's active magic on each not-allowed shelf.

She gets distracted trying to figure out what the magic does.

The shelves themselves--do not want to allow the books on them to be removed, except by their owner and specified other person(s). The books, likewise and separately, do not wish to allow their contents to be accessed by any means except by their owner and specified other person(s).

...That's interesting. Once she realizes what that part of the magic on the shelves is for, she picks a reflection-book off a reflection-shelf just to see what it does, then peers at the cover to figure out that part too. But she did agree not to read any of these, so she puts the reflection back without trying to open it.

Meanwhile, in the real world, she's just sort of standing there.

This is an entirely reasonable response to being surrounded by a large number of books.

And once the reflection-book is back on its reflection-shelf, she blinks and looks at her host and smiles.

Tentative smile. Most of seven hundred years of general misanthropy has not done a great deal of good for Kanimir's social skills but he thinks you're probably supposed to smile back when someone smiles at you. Anyway. He pulls out a polished cabochon of some kind of pale blue stone and hands it to her. "If you need me for anything else, tap it four times like this," he raps his hand against the side of a shelf in a two-iamb rap-rap, rap-rap pattern, "and speak into it after approximately ten seconds. If for some reason there's an emergency for which this is too much of a delay, tap it three times in close succession and speak into it immediately."

"Okay," she says, accepting the stone. "Your magic must be really useful if it lets just anybody make things like this."

"It doesn't. It's highly skill-intensive. I'm the most powerful magician in the world because I'm the only one who's spent the equivalent of several human lifetimes studying it. A trinket like this is well within the reach of a normal magician, but even they would have to spend years or even decades of study to do so."

"That's still more than one person per century making useful magic things." She reviews this statement, then amends it to, "Well, probably."

"Many of us create magic items; few of us create large-scale magic items."

"Then I guess I don't know whether it's more convenient for most people than the way things work on my planet."

"...Well, most people don't know that magic exists. I don't know how that started, but no one's wanted to be the first one to change it."

"...How do they manage not to notice?"

"Well, no one has selfspaces..."
