Two kinds, psions and mages, collectively 'eclipsed'. The former does mental effects and divination and stuff, the latter does physical effects. We happened to land shortly before an eclipse of the sort during which many preteen children get their magic, which event apparently has the precognitives running around crazily; it's possible someone foresaw me unleashing enormous clouds of mosquitoes and read into that? The psions apparently bounce off you.

I would think that keeping you immobilized in a room without explanations of any kind would be a disproportionate response to clouds of mosquitoes.

Well, it's also possible they foresaw saying hello politely and then being told that I was a demon who'd destroyed a planet recently or something.

That... could have produced such a reaction, yes.

Ozone all wrapped up. Time for a new task?

Would he like to reverse some Saharan desertification?

Sounds useful. He'll do it.

Cam can keep this up for a while.

So can Korovai, particularly as he no longer needs to sleep.

Isn't that handy?

(Meanwhile, Cam can lightly terraform Mars. He cannot do a very complete job of it because he expects to vanish in a few days but he can do atmosphere and water and seed populations of some plants.)

No one else seems inclined to interrupt him. It is probably difficult to keep ahead of someone who can teleport, especially when they are apparently impervious to your future-sight, but even so he wonders why no one has made any creative attempts to contact him yet. At least not any successful ones. They might be trying things that just aren't getting anywhere.

Eventually:

...found the social weirdness, or at least a big chunk of it, but it doesn't seem likely to be all that relevant to what we're up to.

I have no particular interest in their social weirdness unless it seems likely to make them more comprehensible if they ever catch up to me.

They will expect you to have an extra genderlike thing. Not sure how to expect them to react to 'in my world we don't do that'.

Perhaps I can just avoid ever talking about it at all.

Yeah, they don't seem to be having any luck catching you.

There is a lot of plastic pollution floating in the sea and my world has a bacterium that works on that in the presence of an activating chemical so it doesn't eat anything plastic that is intentionally oceangoing -

Resumption of worldfixing.

There is something slightly satisfying about worldfixing. And it's an intrinsically worthwhile endeavour, and the practice will be useful if he encounters another Earth without Cam there to help.

When he's replenishing populations of very stupid prey species in depleted fisheries, somebody finally catches up to him.

"You're hard to find!" he says accusingly.

"Yes, that's true," says the man in the flying stone boat. "I apologize."

"Are you some kind of, what, combination mage-psion -"

"No. I came here from another world, where magic operates on entirely different principles."

"...and, pardon me for not being able to tell, probably it's because you're from another world, but dom or sub -?"

"I don't know what you mean."

"Uh, dominant or submissive role...? An omniglot would be able to understand me, I guess you're not technically an omniglot..."

"The dialect of this language that I speak comes from a slightly different world with different social customs," he says. "It may be that the concept you're referring to does not exist there."

"Nah, like, even aliens would have to have it, it's basic, it's like, do you want to be the one giving instructions or the one taking them? Or one most of the time and the other Tuesdays, switches are fine, I don't judge."
