A loud crack splits the air. A strange man appears ten feet in the air. His body slams into the ground.

"Argh! Fuck! What in the—" He's not speaking the local language.

Well!  That definitely qualifies as interesting.

Does the man look like a cultivator?

The man is garbed in a traveler's outfit of an unusual style. He wears a metal breastplate over it. His cloak shimmers blue with silver inlays. A thin silver headband adorns his head. A large pack is slung across his back. A satchel is strapped to his side. His walking stick, three feet long and carved like a fighting staff, rolls across the floor.

He starts pulling himself up and looks around. "Some sort of teleportation trap? To an inn? Why?"

The clothing is very foreign, as are the features.  Having a large pack instead of a qiankun pouch and no sword probably means non-cultivator.  Wei Wuxian was worried that a mundane person would be hurt from a fall, but that doesn't seem to be a problem?

Wei Wuxian stands up and approaches.  "Hello!  You look like you're from pretty far away."

The language the stranger used is just as different as everything else about him, so this is unlikely to be understood.  At least maybe the tone of voice and smile will be reassuring.

Oh no. Everyone here looks Tien and they're speaking a language he doesn't recognize. Being marooned in Tian Xia is not a situation he wants to think about.

He turns to face the smiling man and tries greetings in Taldane, Varisian, and Dwarven. Maybe they have dwarves in Tian Xia and the language is known?

Nope.  Wei Wuxian says a few lines each in the dialects he knows, in case that helps.  

Writing might be more useful.  The silver inlays and headband imply someone wealthy enough to be literate.  Wei Wuxian is never without a bit of charcoal and paper (what if he has a brilliant idea out in the forest and needs to write it down?) so takes over the nearest table and scrawls a quick "Can you read this?" onto it to show to the man.

Yanor can read! He cannot read that. Using charcoal for writing is... odd. It looks like he will have to use his spirit's daily tongues on this.

He speaks an incantation and flicks his hand a couple times. A strange and subtle energy forms within him. "The bird and the cat ate the apple." This language has weird structure. "Hello! Can you understand me?"

"Oh, wow, so you are some kind of cultivator.  Yes, I can understand you.  Your translation ability is really cool!"

"Thanks! I don't precisely know what a 'cultivator' is. The language spell only gives me the literal meaning of words."

"Someone who has cultivated the ability to do things like cast talismans and fly, which we then use to fight against monsters, undead, and other supernatural problems."

Oh, adventurers. Fair enough. "I would use the word 'adventurer' for that general concept. My name is Yanor. It's good to meet you. I fear I'm quite lost. Where is this place located?"

"This is China.  Near Qinghe, specifically.  

"It's nice to meet you too, Yanor."

Now, how to go about introducing himself?  Obviously he can't claim to be Wei Wuxian, the Yiling Patriarch returned.  Even if Yanor doesn't know or care about his past, they're in earshot of townsfolk who would panic.  Best to stick with the name of the body he was summoned into.

"This one is called Mo Xuanyu, and my companion here is Lan Wangji - called Hanguang Jun to those who aren't such good buddies as the two of us."  

He looks over at Lan Wangji for confirmation.  Lan Wangji's stoic face shifts minutely.  

Those names are definitely very foreign. He nods to both of them. "I've never heard of China. I'm from the city of Magnimar in Varisia. There is a land, known to me as Tian Xia, far to the east and across the sea. I met a Tien traveler once and he looked a little like you. If China is located where I suspect it is, I'm not going to make it home anytime soon. The quickest route is across the northern ice and over the Crown of the World."

"I haven't heard of Tian Xia or Varisia.  Or the Crown of the World, though that might be a terminology difference.  It is colder to the north."

"At the very north of the world it gets so cold the ocean is frozen into ice. That's the Crown of the World. Tian Xia is on the opposite side of the world from Varisia, so the shortest route is up and over. It's... possible people in Tian Xia don't use the words 'Tian Xia' but I was definitely under the impression they did."
