The narrator has a good idea of what it looks like, so it's fine. 
Nagesh has to cut down on his voice projection a bit. Usually he speaks like he's giving a presentation to someone across the table. A long table, or not, depending on the circumstance.
"Not many people here," he observes wryly, which he means no one else is here. Probably the only person who'd think of studying right before a possible invasion is this guy, and he dragged Yvonne into doing it with him, too. Well, finding books for his studying, anyways.

"So the person who told me 'The Clocktower is full of booklice' was overexaggerating, then..." Nagesh murmurs to himself softly. 

"They introduced me to just about all in the vicinity with 'Booklouse,'" Nagesh answers all innocently.

Nagesh grins.
"Well then, Miss. Yvonne, mind introducing me to how to search for materials in the library?" he asks.

Nagesh takes a while to think. He indicates his thinking by slightly moving his eyes around, though he doesn't usually do that. 
"Hmm, I don't know how to describe something without a name, which is why I'm looking for it in the first place. It's my way of magic, I suppose. Would you need an example of it? I'm sure it will be helpful." 

The mage laughs slightly at that. "I dare say I'm not that unrealistic. Don't worry; this will only take a few moments." 
"I'll make the example small." And with that, he begins. Small glowing particles envelop his left arm, but it is his right arm that he raises. Without particular precision, he directs the direction of which his arm is facing towards a row of bookshelves; the particles bind together quickly, one by one, as if reaching for the shelves as well.

The narrator would actually be more vexed if she said she'd seen it, since for all they know, this type of magic is literally an original concept and thus should have never been seen.
"Good. I'll take that as praise for me being somewhat creative," he says with a laugh. Notably, he's able to do so because the magic didn't involve chanting in the first place. As he speaks, the particles reach the bookshelves, amalgamating and then spreading. The spreading process takes less than a second--it's as if the particles enveloped the shelves, keeping careful distance from the books themselves, and then within a second, just about everything on the bookshelves rearrange. Everything being...books, of course. There's not that much on that particular shelf. But the books change their positions within a second, and the particles disappear as well, without any particular dramatic flash or similar effect.

"I suppose. Really, it's just magic, even if the method is due to a specific type. At least, according to information I have seen so far, such a description would be accurate," he informs. "Thank you for the compliment, by the way. Very interesting way of putting it."
How convenient would it be if the CDs were just books that he could re-shelf, huh.

"I don't suppose you've seen it before?" he asks back, sounding a little hopeful.

"If we find ourselves in each other's vicinity in the near future, I would be glad to show you. Though, the demonstration would not come with labels and subtitles," he adds. 
He means if they find themselves fighting in the same area, she'll probably end up seeing it anyways.

"An excellent question." He regards the books passively as if looking over a herd of sheep. A weird comparison, but an imaginable one considering his primary weapon of choice.
His smile is climbing back up his face as he admits, "I suppose I asked you here for permission to use some magic here instead of anything else in particular. Though, this would usually not be the case, but if it's efficient..." He grins, letting the sentence trail off and close itself off in a finish.

"If there were, I'm sure the rule has been broken enough for this transgression to be viewed lightly," he reassures back.
For instance, remember when ducks were summoned in here, Yvonne--

"I'm sure you do. You seem like that type of person," Nagesh evaluates. His smile is supposed to convey that he is still well-meaning, not teasing her, but he adds, to no help: "It would also seem like you are also someone who unintentionally added to chaos once or twice, however."

He smiles back. "In a sense I cannot say that I understand, but in another way, I do retain that understanding," the mage admits. He lifts his arm up. "Perhaps it is because Abstraction is somewhat like what you said," he compares as thick, glowing golden strands loop around his uplifted arm and make the bottom of his irises glow bright with their hue. "Chaos within order; order within chaos. One cannot exist without the other, and thus neither can be complete without being together. What a strange yet endearing world this is, just as all worlds are," he states, the strands dimming, combing into ever-fading strata, and then dissipating into the surroundings' majesty.

"Good. I could barely understand the bases of philosophy myself when I was young," the mage says, watching the last of the strands fade. His eyes, too, fade back into their usual maroon. "Not that I can teach the subject now or anything of that sort, but at least I have not become someone I would not have been able to relate to," he clarifies with a small smile at the corners of his mouth.
