Lotus didn't start the fire - that was probably the dragon, she doesn't know for sure but it's the most likely hypothesis given, you know, dragon - but she was ready for it. She had gone for the library, joining the foolhardy, heroic-minded individuals rushing in and out to save the books. She had grabbed the books she needed and then raced across the campus, heading for the teleportation circles. The building is unguarded, for once - not surprising given, you know, dragon - so she slips in. She picks the nearest circle, disrupts it so it will pick a destination at random - should make her harder to track down if that's anybody's priority given, you know, dragon - and steps in.
She expected some place a bit more settled but she did say "at random". That said... It's dark out? It's was the middle of the day! Where did the sun go?
It should be the middle of the day everywhere. That's how days work.
Light could mean people or it could mean horrible monsters, but horrible monsters come in the dark too and Lotus has the dreadful night vision endemic to humankind so she will gamble on the light being a good thing. Walk walk.
A mansion could mean people, or it could mean horrifying monsters. She's leaning a bit more towards "people" now, though. She casts Tongues and finds the front door and knocks. She is still holding a stack of stolen books but they won't all fit in her bag and she has nowhere better to put them just now.
"Hello, I'm terribly sorry, I seem to have gotten a bit lost. Very lost, actually. I saw the lights..."
The language is unfamiliar, which would suggest she wound up teleporting way farther than planned. Not that that is new information given the part where it's inexplicably night time.
The what or the what now. This spell was working a moment ago...
"Sorry, I didn't quite catch that last bit?"
"I... don't think I know what those are. A phone. Or the internet? I'm not from around here..."
"...No I don't, at least not on my own. I'm cheating."
"I cast tongues before I came to the door? I was studying magic. That's how I got lost."
"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."
"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.
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..."
"It's... a different time? In different places? How does that work?"
