Usual rules apply.Romance is ok.Image is official art from the game.I will help if you don't know about the

jenna: huh? who are you?

- the two arrive at a town, there are many houses and shops and a large church and buildings at the further end -

Kaeya: welcome to Mondstat! There are many places you can visit, but I need to talk with you first.

- you and kaeya arrive at a tavern -

Kaeya: would you like some wine? Or anything else you want?

(What would you like? ,I'm fine with either ways)

(ok im making it easy then)
jenna: no, but, thank you

Kaeya: I'll take a bottle of wine, the usual.

- the waiter nods and brings it -

Kaeya: so, can you explain about where you came from? And may I ask about what the place "Xanorith" is?

jenna: oh boy, ok its a long story though

Kaeya: don't worry now, I have all day.

jenna: ok

Kaeya: I can ask you the same question. You aren't from here, are you?

jenna: no i'm not, i'm from xanorith
(a kingdom i made up)

Kaeya: Xanorith? What on teyvat is that?
(Teyvat is the word for earth in this world)

jenna: its very far

(are you aware of how this game is?)

Kaeya: I see. Well then, my name is Kaeya, A Knight of favonious.

(is it genshin? bc if so i kind of do)
jenna: my name is jenna

(yeah, if you have any questions you can ask)
Kaeya: a pleasure to meet you, Jenna. *He gives a small bow*

(btw forgot to ask but is it ok that she is a princess of that made up kingdom i mentioned?)
jenna: pleasure to meet you as well

(hm, maybe, but that isn't really Isekai, but if you want)
Kaeya: well, let's go to town,we can continue our chat at a tavern.

(if it contradicts the plot you had in mind i can change the oc to a similar one)
jenna: alright

Umbreon: hughg? what the fu- where am i?!?!

Polly: hmm?

Kaeya: and who may you be?

( DADDY KAEYA <3 ) oh... hello who are you

(we are now best friends)
Kaeya: I could ask you the same question now.

(YOU ARE MY FRIEND NOW WE'RE HAVING SOME TACOS LATER) well i guess ill go first, im Grey. and you are?

Oh cool Kaeya, Could I be a character from Genshin?

Of course

Aether: *Wakes up* who, who are you?

Kaeya: my, what do we have here? *Steps closer to aether*

Aether: Who are you? where's my sister

Kaeya: kaeya, knight of favonious. I didn't see anyone else, you were just washed up ashore I'm guessing.

Aether: *Gets up* I need to find my sister

Kaeya: where'd you see her last?

Aether: i, I don't remember

Kaeya: you don't? That's rather rough..

Aether: nods*

(I need an explanation of the game. Also, is that a tail on his shoulder? Can I have a romance one as well? Sorry for this, lol)
Blossom: Who are you?

(the main points about the game is that your character can have a elemental power. One from fire, electricity, water, earth, ice, air, grass. Kaeya over here is an ice user. And the thing on his shoulder is like a feather boa. And romance is okay lol. I'll explain even more later on!)

Kaeya : Kaeya. Cavalry captain of the knights of favonious. And you are?

Blossom: I am Blossom. (I'll choose mah favorite element Ice)

(oo, my favourite too)
Kaeya: I've never seen you around mondstadt. (City/region of air.) Where are you from? I might just have to deal with you, myself if you don't co-operate.

Blossom: (I am just going to say the continent from The Inheritance Cycles.)
Blossom: I-I'm from Alaegaesia.

(YOOO ERAGON FAN?)
Kaeya: that's.. unheard of.. are you part of the abyss order? Is this one of their tricks?

(Abyss order is like a evil organisation of greater and smarter monsters, that's the best I can explain bc I'm dumb myself)

(ERAGON 4EVA BOII) Blossom: I-I'm sorry I-I don't understand. Alaegaesia is home of the Dragon Riders, Elves, Dwarves, and the evil king.

(EEYYYYYYY)
Kaeya: ah...did you perhaps fall from another world? Dragons... Are you familiar with Stormterror perhaps?
(Stormterror is a ancient dragon that is bless by the Anemo(air) Archon (God). It has been recently wrecking havoc in the city and surrounding areas.)

Blossom: I-I don't know, and Stormterror? I have never heard of them. We just have elemental dragons. Fire; Ice; Water; Smoke; and mud.

Kaeya: fascinating..well, let's head to town and talk. You will feel much comfortable,no? Just don't think about any funny business. I have my eyes on you.

Blossom: Oh, 0-ok. *she hurriedly follows him, not used to these lands*

*after a few minutes of walking through the fields, you guys arrive at Mondstadt. The city of freedom.*

Kaeya: here we are.

(The image is the city)

*she looks amazed* This is bigger than any city in Alaegaesia (if my calculations are correct)!

Kaeya: is it? That's interesting.. how is Alaegaesia if I may ask?

Blossom: It's... Horrible under the kings reign. He has these weird zombies lurking around hunting the last Dragon Rider down and in the process destroying towns. Luckily Eragon is safe in Tronjhiem and I have said too much. *she covers her mouth and looks down*

Kaeya: ah, don't worry. Since you are gave information about your land, I will give about mine. All I have to say is.. welcome to mondstadt! The city of freedom and romance!

(Oh yeah, Mondstadt is like a reflection to Germany. Same goes to other nations/regions like Liyue is china, Inazuma is Japan, Sumeru is India/Persian/Egyptian/middle eastern and Fontaine is I think France bc it's not out yet)

(NAZI) Blossom: *she giggles a little bit* The freedom part reminds me of America. Home of the Free and the Brave.

(LMAOAOAOOA)

*The streets are filled with citizens, all happy and smiling. even some knights. The knights bow to Kaeya after seeing him. A hand behind their back and a salute.*

(Description of a bow would be normal for a eragon fan lmao)

*she becomes shy and continues to follow him shyly.* (I have updated her backstory so she is now a German-American child. She is the heir of Adolf Hitler but tries to hide it from most)

(excuse me what 💀. It's not actually Germany, it's just based on it 😹)

*she continues to follow him*

(nvm just stick with the other backstory)
