"Of course!"

Miles grins.

"Thought so. If someone comes out and wants to know why you're talking to yourself, or talking to a strange Cetagandan-looking kid, blame me," he advises.

And he goes over closer to the house, and carefully disembarks from his horse, and goes inside.

"So how does all the stuff work and what are all the me like."

"...that's going to take a really long time it might make more sense to give you a computer and then you can read it. Are you standard humans, is there any reason to worry the computers might not work?"

"I don't know what the standard is but we're humans. But I was left on a doorstep in a basket so I'm less sure about me. And Miles has a weird medical thing."

"...then maybe we shouldn't risk it? It's a brain implant so it'd be bad if it didn't work for you. I can check with a basement-dweller -" 

He tries. He scowls. "...are you magic?"

"...no?"

"...yep, you're magic. Otherwise I could make a non-sapient copy of you to check if chips're safe and I can't."

"......okay, so how am I magic?"

"I don't know. But you are. And it's not just that you have magic, I could still conjure you if it were that. ...anyway, can't chance a brain chip."

"Oh well. ...so how does the stuff work and what are the mes like."

"Um. So there are a lot of dimensions, all the ones we've found so far are inhabited, some have magic and some don't, sometimes the magic is only people who were born there or conceived there, and sometimes it only works within the dimension or its neighbors, but sometimes it's transmissible. There're a couple ways to travel between worlds. I invented one, and an alternate universe version of me in a different dimension invented another one, and a you invented the third one, and we use those to explore for new worlds and fix them up."

"Oh cool, are you going to fix this one up now?"

"Yeah! Well, I was gonna just ask you how to do it because you know more about it since you live here."

"Probably first you should get unlost so all the mes can help."

"If I could go home I would have obviously done that."

"Oh. I thought maybe you just came and found me first, I don't know how your teleportation works."

"You can only go to worlds that are next to each other and there was an accident and this world isn't next to any of ours."

"Oh. Are you ever going to be able to get unlost?"

"Worlds don't have infinite neighbors but I don't have a good way to check them all, some worlds're dangerous to land in. They're probably checking from their end."

"Dangerous to land in how?"

"Break my magic, mostly. We've only found one world like that but there could be others."

"Do you need your magic to live or would you just get stuck?"

"...probably just stuck but that particular world also squishes people for hubris and I kind of have a lot."

"Oh, that sounds bad."
