"Ah, you've got somepony minding you? I can tell you're juvenile for the species and approximately how much but that doesn't tell me about your social status, you see."

"Yes. I have an adoptive mother named Clover Honey and she's not bad about things like letting me stay late at the library, but I think she wouldn't want me to stay overnight in strange worlds at least until I was confident I could get home on my own if I needed to."

"I don't know how well a unicorn spell will do at interfering with a summon," Kaylo says. "It'll be worth testing, anyway - under circumstances void of unicorn magic you can only go home from a summon if the summoner reverses the spell or dies. Well, or if someone does a break, but hardly anyone's any good at breaks."

"We can experiment," Blueberry says cheerfully. "It'll be fun."

"It's good that your mom's well-behaved about library-ing," Kaylo mentions.

"Yes! It's very convenient."

"Anyway, I'll go see about summoning you - and you wanted me to tell that purple and green fellow something?"

"Well, maybe, but I think if I'm going to be visiting the world in three hours anyway it doesn't matter as much. I was going to say that he should go somewhere there aren't any dragonlike creatures nearby - would that be easy to do, or are there lots of dragons around where you were?"

"Not a ton. Headmaster's wife, me, one other student."

"Well, that's pretty easy then. Tell him that if he really wants to go home right away, he should go somewhere there aren't any dragonlike creatures nearby, and if he doesn't he can wait for me to show up and talk to him myself."

"Sure thing."

"Thanks!" says Blueberry. Then she floats her scroll of notes in front of her, opens it, and picks up her quill to start scribbling a second version.

Kaylo peers over her shoulder while she does it. Well, pretty much over all of her.

Kaylo, being about to be subject to this spell, is particularly concerned with the "safety safety safety" section.

One entire list item is just the word 'Teleport' - the first one, in fact. Then there's 'extra attention: land comfortably' and 'extra attention: cancel for danger' and 'extra attention: do not land on people'.

"I assume 'teleport' has its own list of parameters you're referring to here?"

"Yes. Teleport safety is its own thing, I don't need to re-list all of it - the spell would be worse if I tried to pay individual attention to every single thing, because then I might miss something. But most of the time when ponies teleport they're teleporting themselves and they can either see their destinations or are pretty familiar with them, so an interworld teleport needs extra attention to things like not sending you if something unexpectedly dangerous is going on where you would be put, and not dropping you on top of a table or another person or into a pond."

"And the spell understands 'danger' as a concept just fine?"

"Yes."

"How does it do that?"

"Well, most ponies understand 'danger', don't they? It's not that complicated of an idea."

"But you're sending me to another world. There's potential dangers you've never heard of," says Kaylo.

"Yes, that's why I made sure to have unexpected dangers as an extra point. I don't think you have a different definition of danger, do you? It still means 'things that might hurt you', more or less."

"Yeah," Kaylo nods.
