The place she is in is some kind of city that looks like what would happen if a Ren Faire and a fantasy novel got into an argument with a textbook about the middle ages. 

There are towering spires off in the distance, but otherwise three-story buildings are the tallest things in the skyline, and even they aren't that common. She appears to be in some kind of open square; to her left is the entrance to an open market with shouting vendors calling people to view their wares and thrifty-eyed customers haggling ruthlessly. To her right and in front of her are residential streets composed primarily of two-story buildings dotted with three- and one-story buildings. 

Some people were startled by her arrival, but soon go back to their own affairs; she is just one more face in the crowds. A mother with a toddler clutching her skirt attempts to shoo her out of her way. 

What.

For a moment, Margaret has no hypotheses about what just happened. Then she has too mamy hypotheses. Maybe she was hit on the head and dropped in some extremely high-effort LARP village, possibly by aliens. Maybe she's in the Matrix. Maybe she was in the Matrix and now she isn't, though you'd think that would involve the sensation of waking up at some point. Maybe she's dreaming. Most likely she had some kind of stroke or horrible neurological thing and now she's hallucinating her entire set of experiences, but that possibility can kind of get ignored because there's not really anything she can do about it. 

After about a minute of standing there staring at first everything and then nothing including a couple of failed attempts at the mental action that always suffices to wake her up from a lucid dream, she decides to go back to her usual strategy of "interact with the world around her as if it exists and is important". She looks around for someone who doesn't appear to be going anywhere in a hurry so she can question them.

The mother is drawing water from the fountain that was apparently behind Margaret. 

The fact that the language being spoken around her isn't one she recognizes probably reduces the odds that she's hallucinating a bit, but apart from that it's pretty worrying. She turns to the mother at the fountain and says, "Hello. Do you speak English?"

The mother gives her an odd look and says something that isn't English. 

Yeeeaaaah, she figured. Time to learn a language by immersion; if this is aliens running a LARP she hopes they're happy. Point at herself, "Margaret". Point at the woman and cock head?

The woman says something incomprehensible and irritated, points in the direction of one of the spires, and goes back to getting water and paying attention to her small child. 

Reasonable. She wouldn't've had time to teach a random lost person English this morning. Maybe the thing she said was "go be confusing and foreign in that tall building". If she's very very lucky, she said "go be confusing and foreign in that tall building, it's got academics in it." She sets off thataway.

There is quite a bit of walking between where she landed and that spire. 

Over the course of the walk she observes: 

--Horses are in common use

--The streets are much cleaner than you would expect from the apparent tech level. 

The lack of poo everywhere is really reassuring. Before she gets too far she realizes that she needs to remember where she started in case it ends up containing clues to how she got here. Are there street signs so she can memorize the the nearest intersection?

There are lots of things with writing in a script she can't read on them. None of them look anything like a modern American street sign. 

Maybe she can invent the street sign. Maybe she can invent the printing press or something. In the meantime she takes a notebook out of her bookbag and copies the writing on some of the buildings near where she appeared; hopefully that'll be enough to uniquely identify it when she gets a handle on the language.

Walk walk walk toward the spire, patting the occasional loitering horse on the way if any are loitering and nobody looks likely to object.

There are a few loitering horses. 

Eventually she reaches the spire. It has a thick wooden door with a heavy metal knocker. 

Hoo boy. She really hopes whoever answers the door is more curious than annoyed. Maybe she should have been looking for something that looks like a soup kitchen, if she knew what soup kitchens look like.

Still, best give this a shot. Knock knock.

The door opens and an impeccably well-groomed man looks out at her. 

His clothes aren't of a style Margaret would recognize at all but he still manages to exude an Aura Of Butler. 

She says, "Hello. I don't speak the language here, can someone here help me?" in the hopes that her incomprehensibility will convey the same message as her words.

He makes a butlery facial expression and then gestures for her to come inside. 

Oh thank goodness. She smiles gratefully and comes inside.

He makes another gesture, then says in English, "And what might your name be, miss?"

"My name's Margaret! I'm afraid I'm very lost; I'm so glad you speak English."

"Your clothes do suggest a non-local origin. May I ask why you came here?"

"I came to this city completely by accident, and I'm not quite sure how, or even what city it is. I came to this building because when someone else realized I didn't speak the local language, they pointed me here."

She actually still has no idea what country this is, let alone city, but one thing at a time.

"Ah. I see. Are you a practitioner of magic?"

Aaaand back to "what". If her day hadn't been so weird maybe she'd be thinking "oh great, the expats in this town are New Age weirdos", but her hypothesis space has to account for a lot more stuff than usual.

"No, but I haven't encountered any before. . . . Are you?"

"Miss, this is the Indryat University for Wizardry."
