"I'm Twilight, but I think you already know that. It's nice to meet you!"

"Tell me more about your world! I've only been to one alternate universe so far but it didn't have any ponies* in it."

(*) From Twilight's perspective, Katixa is a very weird-looking pony, but a pony nonetheless.

"Uuuuum, I've only been a person for about a year and a half so I don't know all that much even though my paladin tells me stuff all the time. But it's got evil gods! One of them had a whole country! We have been working so hard to help the country not be the kind of country that an evil god made it be any more now that we have won it from the forces of Hell!"

The words 'god' and 'Hell' don't translate precisely but that still sounds. Uh. Yikes.

... she should, probably, like. Tell the Princess that Equestria has made contact with a universe that has evil gods in it?

"What do you mean, you've only been a person for a year and a half?" she asks Katixa. (Presumably if she were only that old she would have just said that.) "—hold on, I probably ought to tell some people from my world what's going on." And she trots over to the door, pokes her head out, and yells, "SPIKE!!"

"That's how long ago I awakened. Most horses aren't people but very cool special paladins like my paladin have magic that makes their horses people, and I'm his horse, so now I'm a person. It was very startling! It happened right in the middle of a battle!"

"Oh, that's cool!" Although it seems like it would probably be...traumatizing...to come into existence in the middle of a battle. "In Equestria all ponies are people, plus dragons and gryphons and a few other species. What are most people in your world like?"

     Before Katixa can answer, a tiny* purple-and-green dragon arrives at the door.

     "Hey Twilight, what's—whoa, what is this place?"

"It's a long story. If I leave I can't get back in, so can you go tell the other girls to meet me here?"

     "Sure."

(*) Probably just Small, in Pathfinder terms, though relative to the typical size of a dragon he's tiny.

"Most people have two legs. Hello dragon!"

"Oh, the other world I went to was like that. I don't think it's the same as your world, though."

     "Hello, uh, whatever you are," says Spike.

"I am a horse."

     "Well, it's nice to meet you," says Spike.

     He leaves and one brief timeskip later comes back with five other ponies.

"Hey Twilight, what'd you want us—oh, you found Milliways."

She really should not be surprised but she is.

"You know about this place?"

"Hol' on, what place?—I thought this room was a closet," says Applejack, getting a glance inside.

"Milliways! Best parties in the whole multiverse!"

"Hello! I'm Katixa!"

They have all by now learned to ignore Pinkie Pie being Pinkie Pie.

"... anyway, Katixa, these are my friends Applejack, Pinkie Pie, Rainbow Dash, Rarity, and Fluttershy," says Twilight, pointing out each of them in turn. "This is Katixa, she's from another world."

"Whoa, that's awesome."

"It's lovely to meet you."

"Howdy," says Applejack, and then a whispered aside to Twilight, "What the hay is going on here?"

"I wish I knew, but basically this restaurant somehow connects to a bunch of alternate universes. The one Katixa is from has evil gods so I was going to ask the Princess if there's anything we should be doing about that."

To Katixa—"Can you summarize the whole 'evil god' situation in a bit more detail?"

"Oh, well, the one who had the country we are working in is named Asmodeus. He's very bad. He's the Lawful Evil god of tyranny and slavery and he rules Hell. But the Glorious Reclamation, that's the paladin order I belong to, and some of its allies, conquered his country Cheliax away from him, and now we're Gloriously Reclaiming it. Except that after the fighting part got over with, this is mostly about riding around together so my paladin can be a judge for a lot of people who don't have a good judge, and he does not like it at all. But now we're in a city doing government things and I think that is better for him even though we do not get to spend as much time together."

"That's awful," says Applejack with frank horror. "Is there anything we can do to help?"

"I don't know! If you are powerful adventurers there are a lot of Good things to do but if you want to help specifically with the government things or the judging things those are more complicated."

From the connotations the translation effect is giving her for 'adventurers', it sounds like the word does describe her and her friends, and only them in all of Equestria. If Katixa's world has a standard word for it—well, she already knew that the other world had a lot of problems.

"I think you could reasonably describe us as 'adventurers' but I don't know how powerful we are by your world's standards. It sounds like your world has a lot more, uh, adventure going on."

"... there actually isn't really anyone else here who does what we do, and we can't abandon Equestria even if your world needs help a lot more, which it sounds like it might. But Equestria is always interested in making friends with people from other places, and that's also part of my responsibility, so I do want to visit your world. But I'm going to write to the Princess first and explain the situation."

She has Spike scribe and then send a letter briefly explaining the situation, including the interdimensional bar and the alien and the evil gods.

"Oh of course if you already have an adventuring job you should finish that before looking for more!" says Katixa.

"Oh, there aren't any emergencies right now."
