Holy cow lady you are terrifying.

"Hello," he says steadily. "You must be Korulen's mother."

"Yes. My name's Keo. I'm very sorry about this," says Terrifying Green Haired Lady.

"I'm Kaede, and it's alright. I mean, not the part where I'm stuck here for the foreseeable future, but the part where I'm here at all is not terrible."

"Korulen said she explained to you that I need to check you over before you can leave the circle; it won't feel like anything and I won't look at anything I don't need to. Is that all right?"

"Sure."

A very precisely controlled tendril of invisible green magic sweeps over his mind, and then Keo steps forward and smudges the chalk line. The ward ceases to exist.

"I'm definitely going to want to learn to do that. The ward, I mean. Wizardry in general." He stands up, dusting himself. "—is Saasnil going to be expelled? Because although I understand the general principle behind the rule I don't feel it's warranted in this particular situation..."

"Saasnil is in an enormous amount of trouble but may not be outright expelled," says Keo, glancing at Saasnil, who shrinks under her gaze. "Same goes for Korulen." Korulen flinches. "In the meantime, what do you need to be comfortable here for a while? The problem that stuck you here will not apply to anyone competently summoned, so anyone you want to contact from home can be fetched, and we can send and summon written correspondence the same way."

"I don't really have anyone I need to talk to, but unless I get my hands on some magical artefacts or scrolls from back home or get some brand new magic here I will eventually run out." He pokes his backpack, on the floor, with a foot. "I got a couple of things here, so that's still a week or two out, maybe, depending. Other than that, er, I guess a place to sleep and a way to get food and stuff?"

"We can put you up in a dormitory here and you can have a cafeteria pass."

He nods. "I'd also like—library access, I guess, or something like that? How much did Korulen tell you—or did you get from my brain—about what I'd like to do here?"

"You can have library access too. I didn't read you on that subject and Korulen only mentioned you'd seemed to find it very important to have ongoing contact between the worlds."

"Well, the gist of it is that you have lots of resources we don't, and the reverse is also probably true, so transactions and other positive-sum interactions can be used to better the lives of several people?"

"You want to open trade relations?" Keo asks, amused.

"Yeah, pretty much. I mean, if you prefer to do charity instead and dump all your ridiculously impossible magic on us that'd be nice, too."

"Elcenia has both trading enterprises and charities, but this as it happens is a school, so I'm not the person to talk to about that."

"Yeah, I'll figure it out. 'Til then, learning new magic is gonna be loads of fun."

"You're not going to be able to learn most of the kinds here; they tend to require being born with the potential," says Keo, motioning for him to follow her out of the room.

He hoists his backpack over his shoulder again and gives Saasnil and Korulen a two finger wave before following. "My kind of magic is basically being able to see and manipulate magic, including using magic I wasn't born with—at least from my world. So I might still be able to figure out a way to make myself 'have been born' with the potential."

"That'd be interesting if you could." She leads him to a magic box at the end of the hall and commands it to go to another hall, which it does.

"I couldn't even touch the wizardry thingamajig, and I expect that's a lack of channelling capacity, but I might be able to get one if I find someone with a channelling capacity who's willing to let me stare at them for a while."

"Everybody from this world has one of those, so that shouldn't be too hard to come by."

"Really? Well, cool, then. I might not even need to pay them, if they're nerdy enough to want to do it in exchange for knowledge about my world or my magic. By the way how long does this translation spell last, do you know?"

"Until Korulen reverses it, which she won't unless you want to replace it with a different one or do without."

"Oh no I love it I'd take forever to learn any other languages I'm not very good at them. So your magic does permanent effects, huh?"

He "looks inwards" at the translation spell.
