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).
"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."
"...but something else might conceivably instead happen. To my ability to use language."
"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.
Kaylo blinks at him, then says, "We hatch in dragon form and when we're twenty or so we start being able to adopt new forms, which are then thereafter accessible to turn into and retain objects tucked away with them like my clothes. It's just like vampire or thudia shapeshifting except that the forms aren't fixed and we get more of them, five is standard, blue-groups get ten, unusual nonblues get four unique nonblues get three unusual and unique blues get unlimited, once picked a form is what it is indefinitely except most sapient forms grow to maturity along with a juvenile dragon which is why I look sixteen but if I turned into a cat, say, I would be an adult cat. The transformation is genuinely instantaneous. Shifting requires that at least a small part of the first and second forms be spatially overlapping but allows otherwise free positioning."
"How much control do you have over your form? Are you always the same biological sex? What's 'unusual' and 'unique' here?"
(Stare stare stare.)
"Unusuals and uniques get extra magic of the kind that their color group already gets extra of, uniques more so - you ever get a look at Keo, she's a unique. Anybody besides a unique blue just picks species, otherwise luck of the draw - except fullblooded dragons match our same sex parents when being matching species - and yes, same sex all the time."
"I look younger than my dad's human form did when he stopped aging, otherwise yes."
