"Yup."

"Do you know if there are any contact points in this dimension, apart from this conversation we're having right now?"

"It was a slow day, that's why I'm here instead of hanging out in the bar, so there's probably nobody there from here right now. I have no way of knowing if someone from this world gets doors regularly, though. Why?"

"I'm just wondering if there's a way to - follow up on this after you're done here."

"Hm. One sec." She closes her eyes and leans against the wall for a moment. "I can teleport back here - I can't always, with spaceships - so I can give you a way to get in touch with me and come back and talk to you again, if you want. I don't usually bring people to Milliways unless I know them pretty well, though."

"Why not?"

"I don't know what happens if I bring someone and they make trouble there."

"Is there anyone you could ask about that?"

Nod. "The bar, but they don't know either. It's not that big of a deal, I don't need to get to know you that well."

"Is there a reason something's particularly likely to happen?"

"What do you mean?"

"I don't usually worry about the behavior of people I hold doors for into public places and I'm curious where that assumption breaks down - the place is private and there's some social expectation of responsibility for your guests? Things are very likely to turn out to have uncommunicated rules about them there? It's more investment than holding the door?"

"A little bit of all of those, yeah. Milliways' magic usually makes sure there aren't people there at the same time who'll upset each other too much, and my magic doesn't have that, and I wouldn't be surprised if it stops cooperating with my magic somehow if I start causing problems that way. 

"How does its magic ensure that?"

"By picking who gets to go there. Milliways does get scary people sometimes, but it almost always turns out that nobody there is bothered by it, or if they are there's always a way for them to avoid them."

"How does it make this determination?"

She shrugs. "Nobody knows. It works, though."

"Do many people on a per capita basis get to go?"

She shakes her head. "It's hard to figure out numbers, but it seems to be very rare. If a friend tells you about Milliways that makes you more likely to find it, but aside from that I've met two different people from the same world less than five times out of thousands."

"And you think that's a matter of few people getting to go, rather than something about sampling on your end?"

"I think so. It's hard to know for sure, of course."

"I suppose it would be! Do you normally live there or where you originally came from?"

"My tribe is my home, of course. I do spend a lot of time in Milliways too, though."

"How would I get in touch with you again if you wanted to leave me something to do that with?"

"I can make something with a portal on it that you can put a note through, or something similar if you don't have the right kind of tech for that. I might not check it every day, but every couple at least."
