Kaede's flying with purpose. He has Information and a little artefact to prove his Information is correct. This will be grand. He's flying and he's grinning and life's (reasonably) good (terms and conditions apply).
"Magic dragon language, very good at having words for things. Won't cough them up if no speakers have the concept though."
"I don't know how it works with respect to that in particular, and my lack of vocabulary to explain how it works is exactly the problem we're trying to solve. Would you just—understand whatever I was talking about even if you'd never heard of a concept I was referencing before?"
"Say something in Draconic?" he asks, paying attention to the different parts to see whether any of them would move.
Kaylo says something in Draconic. This doesn't actually flicker his magic more than when he says things in other languages, but it does a little.
"Do several," he asks, watching for any differences. "And then do some other dragon magic than just talking."
"This is Leraal, this is Alteisec," he switches to his sign language the spell can't handle. He gets out of his chair and turns into an eighteen foot jewel-scaled red winged lizard.
"Okay, I found the bit of your magic that does languages. Draconic or any other languages seem to be the same, though. Can I touch it?"
"What I expect happens is 'nothing.' With magic from my world, it just does a sort of ping, sometimes depending on what the magic is it can react a bit, and if it's an elementalist blessing they can feel a shiver depending on what it is."
"Yes, it is conceivable that something else might instead happen. If I look at it for long enough I'll be able to figure out whether it will, in fact, happen."
"Fortunately my ability to use language is not going anywhere thank you very much, so you can look at it." He shifts back into human form and plops back into his chair.
