"...No I don't, at least not on my own. I'm cheating."

"Cheating?"

"I cast tongues before I came to the door? I was studying magic. That's how I got lost."

"You got lost by--okay, I think you want Kanimir Kozlov."

"Oh, I'm not actually looking for another wizard right now. I just don't know what a phone or an internet is, because I'm foreign."

"...I can't think of anywhere where they wouldn't have heard of phone or the internet."

"Well, it is nighttime here, I'm obviously pretty lost. Uh, it isn't, where I'm from. I'm from" - uh, somewhere that wasn't just attacked by a dragon, in case someone comes looking for a book thief - "Armehil, in Ostrea. Maybe there are phones and internets in Ostrea and I've just never heard of them? I spend a lot of time studying, an internet sounds like some sort of fishing thing so it's maybe a bit outside of my experience?"

This person lives in a mansion, why has she heard of fishing things? If that's what they are.

"...The internet is a global communications network. You wouldn't just have to be from another time zone to not have heard of it, you'd have to be from another time period."

Oh, networked scrying orbs. That's really neat! "Global" wouldn't be her first choice of adjective for that - nor "internet" her first choice of name - but these people can call it whatever they want, she's not here to judge.

"Oh, I see, that's a really clever idea! Time travel isn't really possible and I would be really shocked if I had just stumbled upon it by accident, so it's probably not that, but... what is a "time zone"? I guess if there are places time naturally runs differently and I teleported into one of those that could explain how it's night..."

"...A time zone is a segment of the planet where it's this time instead of however many hours earlier or later."

"It's... a different time? In different places? How does that work?"

"...I mean it's still, like, now, just morning or afternoon or whatever instead of the middle of the night."

"That still doesn't make sense. If it's day somewhere that means the sun is in the sky which means it's day everywhere."

This seems to be an utterly baffling concept. The woman stares for a moment, then says "...So you're from before people figured out the world was round?"

"...I think I am more lost than I thought. The world is not round."

"It definitely is."

"Sorry, I misspoke. This world is probably round. The one I came from definitely wasn't, someone would have noticed and said something."

"...Alright. So, uh, what do you want if not the use of a phone?"

"Well, the guest room sounded really nice, actually. If you are still offering it given that I'm apparently really lost and also an apprentice wizard."

"Kozlov's definitely going to want to know about a wizard staying in his house."

"Oh, is it his house? I guess I can ask him but if he's asleep..."

"No, he's pretty nocturnal."

"Very well. Should I wait here while you let him know, then?" She glances out into the dark.

"...You can probably come in, just, wait here in the vestibule."

"Thanks!"

She does so.
