When he's in a clearly defined location again it's on a carpet in a suburban sort of house. He's in the living room, but he can hear voices in the kitchen around the corner.

Fuck. He tries to Dimdoor back to the mansion, but the spell fizzles as if out of range.

Well. That's bad.

He looks around. It seems to be the house of some very rich person, judging by the carpet, the fact that the walls are colored and the general size of the room he's in.

"È permesso? (May I come in?)"

Well, technically he's already in, but proper form and everything.

...a face pokes out around the corner and yelps and says something in surprise!

He keeps is hands apart and far from his pouch in the universal "I'm not about to cast a spell" gesture (not that he needs the pouch but they probably have no way of telling him apart from a wizard).

That wasn't a language he recognized. The Mists must have brought him quite far.

"Do you speak Mordentish? Darkonese? 𝕯𝖗𝖆𝖈𝖔𝖓𝖎𝖈?"

The face says something! It's not in any of those.

He makes a gesture, stretching out his hand and miming touching: "May I cast Share Language on you?"

These people are rich, they're probably familiar with the spell name - it's standardized even across the Mists for this exact reason.

From the look of blank incomprehension, this guy might not be that rich, or that well-informed, or that within the Mists service area.

Another guy steps into view of the empty doorway between dining nook and living room. He says something quizzical.

So, on the one hand it's incredibly rude to cast a spell on someone who doesn't explicitly accept it.

On the other hand, Share Language is harmless and will make everything else that much easier.

On the mage hand, he has no clue where he is, and he has never seen their style of clothing and in general he feels quite lost.

Well, there is a thing he can do to get more information without needing to touch them. Hopeful they don't get startled, but they're most definitely not mages, and they're not armed, so it's probably fine.

Detect magic. Is there anything magical in the room? He'll look at... that huge black rectangle of vaguely reflective glass first.

There is no magic here, including in particular the big black rectangle.

Well, in that case.

He casts Share Language and then slowly walks towards... the first one who appeared, making it clear that he's going to touch him with a finger if they're not stopping him.

That one looks anxiously toward the other one for direction, but the other one doesn't know what's going on either!

Then he will get poked. As soon as the spell lands Reed takes a couple steps back and bows slightly.

"I am de Book, Reed de Book. I am incredibly sorry to have intruded into your home. I did not intend to, I was carried here by the Mists and well, we all know how they are."

"No we don't?" says This One incredulously.

No magic items, didn't recognize Share Language, weird clothes, not familiar with how the Mists work... where is he?

"I regret assuming more shared knowledge than we do have. May I know... where are we at the moment?"

"...you're in our house!" And then he breaks off from attending to Reed to answer a question from the other one in his own language.

"And I'm sorry for that. Would it help if we had this conversation outside instead?"

"How did you even get in here? We have an alarm system!"

"I was talking a walk to calm my mind when I inadvertently stepped into the Mists. When I got out of them, I found myself into your house. So I didn't technically get in here, which is why I suspect your Alarm didn't trigger."

"I don't know what the Mists are!"

"They are a mostly-impassable layer of fog around countries. If you step into them there is a good chance you'll wander aimlessly until you find yourself miles away. Occasionally, you'll find yourself on the other side of it, in the next country over. And sometimes... they'll just take you Somewhere Else. Someone speculates they have a mind of their own, but it's hard to learn much, especially when people who try investigate them tend to disappear for the obvious reason."

"That isn't a thing!!"

Slow blink.

"You seem to be distressed. Can I do something to make the conversation better for you? Would you rather not have it at all? I have some* more casts of Share Language - the spell I tagged you with that allows you to speak my language - and I could have this conversation with your associate if you'd prefer that."

* technically another 30ish but only if he did nothing else with his magic for the day.

"Brian is not excited about you having teleported into our house either! And - how can it have been an accident if you can also cast spells on purpose -"

"Well, I am sorcerer, but... I got distracted, and got transported here against my will. Would you like me to just... leave?

"What's a -"

There is a ringing noise from Jackson's pocket.

"Uh. Do you mind if I take this."

"I'm already imposing too much, I obviously don't mind."

Detect Magic on the source of the sound?

Not magic!

He pulls a rectangle - like a smaller version of the one Reed was looking at - from his pocket, and it lights up, and he pokes it and holds it to his ear and has a conversation in the local language.

Not-Brian is clearly having a conversation with the rectangle he grabbed from his pocket, it's probably some kind of intelligent object? But the light was not magical, so... some kind of bioluminescence maybe?

Let's hope the object is smarter than Not-Brian, he seemed a bit slow on the uptake.

"Uh, my old classmate wants me to take a picture of you for her?"

"I'm not familiar with what that entails but if it's not harmful you can go ahead, I always love trying new things!"

"...it's not gonna hurt you." He holds up the rectangle. It flashes a bit of light at Reed.

"Yupp, didn't hurt a bit. Which reminds me: I have some quirky healing and haven't used it yet today, so if you need any I would love to make your day a little better. It also covers exhaustion, blindness, deafness and diseases."

"We're... fine..." says Jackson dubiously, poking his phone. "Okay, uh, she's gonna talk to you in a moment."

"Lovely, looking forward to it!" it's kinda weird that not-Brian had an intelligent object as classmate and is now carrying it her in his pocket, but the world is vast and there's always more to experience.

Object goes back in pocket, actually.

[Hi, mysterious guy.]

[Hello, voice in my head which I'm definitely not hallucinating.]

He didn't even feel the Telepathic Bond take, which means that the caster probably overclasses him by circles. No use in worrying about a possible fight you have no chance of winning anyway.

[I could also commandeer Jackson's phone for a voice call, if that's a concern you have, but then I'd have to make him translate and my telepathy doesn't require it.]

[Well, built in translation sounds convenient. Also I have no clue what a phone or a voice call are, so telepathy seems like a good choice.]

[Jackson would have used his phone to take the picture of you, so that I could target the telepathy; they can also do other things than that, like transmit voices.]

[I'm confused. The object he used to do that] who is not his ex-classmate, apparently [is not magic, so how does it transmit voices?]

[...I'm not sure what kind of explanation you're imagining there might be or if you are explicitly considering the possibility that it would be a time-consuming one.]

[Explanation is not time sensitive. Not bothering your ex-classmate kinda is, he and his associate Brian seemed pretty bothered by my presence. I could just Dimdoor out of the window, but I don't want to spook them further.]

[I'm talking to Jackson too. They were pretty concerned about the possibility that you were a hostile intruder but they are not unwilling to help you out if you are a magical accident.]

[I mean, I guess the Mists do count as magic? It was definitely an accident, for sure,  I don't usually enter people's houses without permission. Well, there was that one time but it was for a good cause, he had been murdered and we didn't want the assassin to notice he got better.]

[...I guess that sounds like it might be a good reason. I don't know what the Mists are.]

Ok, this is now outright bizarre. A mage not knowing about the Mists is... how?

[They look like fog, and if you wander into them you can find yourself elsewhere. Usually just a couple miles off, occasionally the next country over, and apparently sometimes you just end up in someone's house.]

[I didn't notice you creating the Telepathic Bond, and you said you used a picture of me to target it? You must be quite powerful, I'd love to learn more] about you [from you.]

[The Mists are not a phenomenon known to this planet. It is very cool that you have your own magic but ours is not particularly teachable.]

[This... planet? I was in Souragne before being transported here, and my party and I are originally from Richemulot, do you know where either is in relation to where I am now?]

[Oh, you don't have wizards? That seems such a pity! Don't get me wrong, being a sorcerer is the best, and our cleric is alright, but after years of traveling together I think I understand how the flexibility our wizard has is valuable, he got us out of pretty sticky situations.]

[Don't tell him I said that though. I have a reputation to keep.]

[Do you not know what a planet is, or are you merely surprised to discover that you're on a new one? What we've got here is mages and psions.]

[I... don't know what a planet is, no. Psions... I had heard stories, never met one. What kind of mages do you have? You said your magic can't be taught, so not wizards, I'm guessing sorcerers and clerics?]

[You are reading too much into your preconceptions about what kinds of magic exists. We have exactly two kinds of magic. All psions can learn the same set of possible powers, and all mages can learn the same set of possible powers; there are kinds to the extent there are specialists. Which is a considerable extent - Jackson is also a psion, he just picked up completely different powers from me.]

[Uh. I am a sorcerer. I means that I don't get magic by learning but by] being awesome [being born with it. It usually runs in bloodlines. I don't get to pick which spells I have access to, but in exchange I get more tactical flexibility and some unique powers. Mine seem to be centered about fire but I also get some quite varied healing - diseases, blindness and deafness included.]

[Neat! The language thing you did would for us be a psion sort of thing but healing and fire are both mage things. Mages affect physical things and psions interact with nonphysical things - information, illusion, intellect.]

[Those have completely different distinctions from the ones I'm used to! In general our clerics are very good at healing, good at support magic and not particularly strong at damaging foes, whereas arcane casters - I am one - are pretty good at elemental energy but usually don't have any healing - mine is an exception, and a limited one at that.]

[I'm very good with fire though. I can survive taking a particularly strong fireball to the face. Or a couple average ones.]

[Well, I have little idea what the average strength fireball might be on whatever nonplanet you come from. A planet is a ball of rock thousands of miles across, the surface of which is the land and ocean on which most business is conducted, and planets form under a paradigm according to which any sufficiently large item pulls things toward itself in the manner you appear to expect by way of knowing how to stand up and so on, such that the air and so on all stay nearby.]
