"Are you a dragonlike creature?"

Who comes back in, and flicks her tail in a shruglike fashion, and opens up her other-direction sending scroll, and sends the duck back where she came from in a large puff of glittery black smoke.

The duck swims into her little hidey-hole.

Blueberry starts trying to refine the spell some more. That flaw is turning out to be much more inconvenient than initially projected.

And a couple hours later, Kaylo summons her.

"Hi, Kaylo!" she says cheerfully.

"Hi, Blueberry! I tried to get out of it but apparently if I'm gonna let you out of the ward, the headmaster's wife needs to check you out, that's only necessary the first time and shouldn't come up again. She just does a mind scan thing with green-group dragon magic, she won't look at anything besides whether you're dangerous. If you want to skip it I can send you home and we can just work in Equestria instead, she can't stop me from being summoned. Oh, and this is Aar Kithen, but he can't tell how old you are by looking, nobody except dragons is going to be able to do that unless they see more ponies, I kind of recommend not bringing it up."

Blueberry giggles. "Okay. Sure, I don't mind a mind scan. Although I'm curious about how it works!"

"Keo's the only person who can do it at the moment," explains Kaylo. "Occasionally a dragon hatches with extra dragon magic and can do extra color-group-relevant things. Green groups are empaths, ones with a little extra are telepaths, ones with a lot extra are pretty arbitrarily mentally powerful. Aaaand she says she's done -" He turns to Aar Kithen, says some things in Leraal, gets a nod, and smudges the chalk. "There you go, she's all done, congratulations, you're certified safe."

"Dragon magic sounds interesting. I want to learn all about it!" she says brightly, trotting out of the circle.

"You and me both!" he says, waving at Aar Kithen. He pulls a scrap of scratch paper out of his pocket, looks at it, puts it away, and casts a spell. "There's your translation, now anybody'll understand you when you talk and vice-versa." He leads her out into the hall.

"How convenient. So what are we looking at first?"

"Wanna see the library and get sort of generally oriented?" he asks. "Oh, and maybe Joy's still there if you didn't get him back."

"Lift's this way, do you have lifts?" The lift is a tiny little room.

"We don't! What's a lift? Does it lift things?"

"And moves 'em in other directions. It's faster than stairs, and in this building, less badly enchanted - don't go in the stairs unless you have enough oomph to teleport somewhere that is not the stairs while disoriented in space." He shuts the door and says, "Library," and the lift moves.

"Noted. This seems really convenient. I wonder if I could figure out how to enchant something like it at home."

"They're mostly only worth it in larger buildings or sets of them like this campus. Really tall buildings often have ones that only go vertically."

"Buildings in Ponyville mostly aren't big enough to need them, but in places like Canterlot and Manehattan it's a different story."

The lift comes to a halt and the door opens on the library. It is a fair bit bigger than the Ponyville library.

"Oooooooh. It's much more impressive in person!"

"Isn't it just? How about you find Joy and I'll run up to my room and get some notes on some things?"
