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).
"It seemed to be very insistent that I'm not supposed to do anything to it before I even tried doing anything much to it."
"...well, if it let you do things to it it wouldn't be a very good ward," says Brown.
"I'm not particularly used to magic being able to have such strong opinions about what I do to it, even wards. Anyway, people from my world don't know about other worlds, I'm pretty sure, I only just inferred their existence by you and how different the magic here is, I am kinda freaking out. I mean, it's really cool and stuff, but I feel somewhat iffy about the ethics of importing a rando from another world and then exporting them without so much as a by your leave, and if you have this world-interaction ability at your disposal just like that I'd really love it if you wouldn't send me back immediately."
(And in the meantime he'll do some more metaphorical squinting at the ward to see whether he can find anything like a weak spot or - well, just understand it.)
The ward is very robust! It does the thing that it does extremely well.
"...huh?" says Brown.
"Wait, so are you glad we summoned you or not," says Blonde.
"I'm glad you summoned me, in particular, I'm not sure summoning random people is a good idea, in general, and I'd like you to not unsummon me - for now, anyway."
Sure, but is there a source, is there a battery, is it embedded on anything, would it contain his magic... He's not asking any questions consciously, merely looking and trying to get more information. He doesn't even want to do anything to it, it's a very sensible idea, but he's kinda tickled by it.
"We haven't even shown you to Nemaar yet," agrees Brown.
The ward draws power from THAT ENORMOUS THING OF POWER ALL OF EVERYWHERE IT IS VERY BIG. He cannot magic through the ward unless his magic happens to carry on pure light or sound, or count for a very rigorous definition as "air".
- okay whoa he even takes a step back.
"I meant even after you'd shown me to Nemaar - why is there an enormous thing of power all of everywhere that is very big?"
"We can't keep you in our dorm room forever," objects Brown.
"...what are you talking about?" asks Blonde.
"You could keep me somewhere else, and I'm talking about the - power source? - of this magic ward. It seems to be literally everywhere I've never seen anything like that but that's a given."
"We can't let you out, you might be dangerous," says Brown.
"...the wizarding reservoir?" asks Blonde.
"That sounds grand enough, yes, what is it?"
"It's where wizard magic comes from."
He tries to see if he can draw some magic from it while he asks, "Does it just - exist, there? Everywhere? As a feature of nature?"
Nope he is not allowed he is not its friend.
Well, there goes the infinite mana hack, then. Or, if not infinite, fuckton mana hack.
"Okay. So ah. Let's start this over. Hi, I'm Kaede -" glance at the pointy ears "- human. Nice to meet you."
"I'm Saasnil and I'm a human too," says Brown Human.
"Korulen," says Blonde, "elf thudia."
"Where I'm from the only sapient species is humans, what others are there here?"
"Uh - I'll probably forget some -" says Korulen, "- dragons halflings vampires leonines skyfolk merfolk -"
"Dwarves," puts in Saasnil.
"- dwarves, pixies fairies sprites, wolfriders... that might be all of them."
He blinks. "Can we start with elf thudias?"
"Oh, thudia just means I'm half dragon," says Korulen, "I'm mostly an elf."
"Oh, your sapient species are interfertile?"
"Mostly. Especially dragons."
"Huh. And how are you half dragon but mostly elf? And... aren't dragons huge scaly flying things?"
"...yes, dragons are huge scaly flying things, but they can shapeshift, and my mom is a dragon and my dad is an elf, and sometimes half-dragons are just totally dragons, like my baby sister, and sometimes we're more like our non-dragon parents, like me."
"Oh. How peculiar." Can he see anything that seems dragon-ish in the girl's magic? Or shapeshiftingish, or whatever, he's not sure what he's even looking for. "That's species-specific magic, then? Not like wizardry."
