They follow her to do that.

"There's a kind that's controlled by thought. They're very convenient and if you're not used to computers may be easier to learn to use but they require putting a little chip in your brain."

"What a clever idea!"

"...so that's a yes to that kind of computer?" Down the stairs.

"Sure, if it's no trouble!"

"Cam can do it easily. Findekáno, what about you?"

"Sure."

So Cam makes them computers loaded up with the explanations and whatnot.

And they sit down to read them. 

Meanwhile in Godspring a bunch of slaves go missing.

Oh for fuck's sake -

- he has the dimension paused -

"Cam, I need forensics."

"Of?"

"Bunch of people vanished in Birand. I think they were probably rescued - the report that came to my attention is all missing slaves - but I need to know who did it, if that's in fact everyone missing..."

"Okay, when was this?"

"Reported an hour ago. Reported missing starting six days ago."

So Cam goes through the list and does a lot of conjurations and finds some dude - local - performing suspiciously well-equipped breakouts.

" - bet I know who's supplying him. At least she didn't go with the helicopter."

"Helicopter?"

"Talked to a demon in Thrazen who wanted to free all the slaves and, ah, be like Harriet Tubman? I am assuming that's someone on Earth. I explained we were going to wait until the dots are installed everywhere because we need the cooperation of local governments for that and then buy them all out, she said it'd be faster to go fetch them with a helicopter, I explained some reasons that was a bad idea. Can you check who made that gear?"

"Harriet Tubman is someone from Earth, yes. National hero, appears on currency, that sort of thing." Conjure.

"There is obviously a set of resources given which breaking out slaves one at a time is a great idea."

Cam hands him a mini demon. She's familiar.

"Yup that's her. - what do you think I should do?"

"...I have some sympathy for the sort of person who listens to arguments against freeing slaves and then proceeds to completely ignore them in favor of freeing some slaves but she's not being a very well-oiled cog in the machine, is she."

"She could start a war if Birand notices and traces it to their neighbors; she could stop the summoning rollout in Birand in its tracks if they notice and trace it to a daeva -"
