And since, despite the world's admitted tendency towards situations best left in the more dramatic varieties of literature, it wasn't literally a stereotypical gothic novel, Kanimir didn't expect anything in particular to happen. If nothing else, there were far more storms that happened to happen at night than there were potentially literature-worthy shenanigans. So it's completely reasonable for him to be curled up in his grand library, enjoying a book on magical theory.
"I can't see anything there. What is it like?"
"I expect you wouldn't understand the jargon if I tried to explain it. Do you want me to cast the analysis on you so you can perceive the sensory aspect, if not interpret it?"
"...I'm not sure," she says. "Which... hmm."
"I was going to ask a question and then I realized that you have no way of answering it even if you understood it, which you probably wouldn't."
"Ah." Wryly: "The inherent limits of translation spells, it seems."
"If whatever question you had been about to ask would be incomprehensible to me, are you certain it would be relevant? Our magics seem to be different enough that it might not."
"I think it would..."
"In that case, perhaps it would be best to ask in any case. Even if I don't understand to begin with, it may be possible to explain."
"Which..." She trails off again, frowning. "What is the analysis? What does it do? What is it like? How do you attach it to someone? Is it attached to you now?"
"The analysis is a spell that examines magic and presents it in a form comprehensible to the human mind. It gives one a spatial awareness of the structure and type of magic, although what those mean is something that must be learned. It is a focused spell with a human or other sapient being as the target which confers on them the sensory perception of magic which the spell provides. I cast it with myself as the target. Separately, I could cast it with you as the target."
"Does it detach when you stop using it? Or does it stay attached forever after you cast it on someone?"
"It dissipates when you end it."
"Hmm. Then okay, I'd like you to cast it on me please."
He says several of the same words as before, and brushes his thumb across her forehead.
The effect is immediate.
The various magic she had already been able to perceive was slightly more detailed to this way of perceiving it, and other magic--old stuff, inactive stuff--became apparent as well.
"Oh, that's very odd," she says. "I guess you already said you have to learn what everything means, but... that's very odd." And she closes her eyes and stands very still for a moment.
Kanimir has had a long time to learn to be patient.
"It isn't really attached at all," she says, opening her eyes again, "it's just sort of... hanging on."
"In what manner is attachment different?"
"It's not... part of you, I mean, it's just on you."
"Ah. Yes. Is that abnormal, for your kind of magic?"
"I've never seen magic be on things that way."
"How else would they be?"
"Attached, or just part of things without even being separate enough to attach."
