So it's going to be more complicated than wishing the pit to the darkness closed. That's okay. 

How many people are there here, how often does someone get eaten...

How many people where? Out here? Our city? Our country? Everywhere? People don't get eaten in well-kept-up civilization unless they do something stupid.

Like going out treasure-hunting, like we did, that was stupid, says Lightning.

Shush, you agreed.

I'm trying to figure out how fast we need to fix the demon problem. It might be better to go to a city and talk to the people in charge, it might be better to do something now, depending how many people are getting eaten. ...and depending what happens when you get eaten, what happens when you get eaten?

Uh, demon sucks out you and your cohabitor's souls? says Holly. You're dead? I guess there might be kinds that do other stuff too, Book would know, Book knows everything.

No way to wake him up faster?

I'm not tired enough, says Lightning.

What happens if a demon has your soul?

You're dead, Holly says. Do people not die where you're from.

They used to. We fixed it. We're going to fix your world too.

...that'd be nice.

I can't get emotion reads off them.

At all?

At all. Like trying to read a wall.

Maybe something to do with the body sharing?

Maybe? I don't know.

So you're not usually born cohabiting?

Me and Crystal and Book all were but most people are born alone, like Lightning, so Book moved in with him. We live in a pretty rich country so we don't have to cohabit until we can pick somebody, some places they have to move babies in with each other because they don't have a dreamward...

A dreamward makes it safe to sleep?

Yeah.

Okay.

If we can't get readings, does that mean wishes won't work - I can still just teleport all the demons far away from people they'd eat, but -

It doesn't necessarily mean that but it means I can't guess how much oomph somebody has for a wish sans verbal interview and may mean that despite appearances these people have no emotions, like the fluffs.

I can read their minds more than I'm doing to talk, and check that -

Ask 'em first.

Hey! We're trying to figure out if our most powerful magic works here. It only works if you have emotions the way we do. I can check by reading your minds more than I've been doing. Do you mind?

...how does that work, anyway, says Holly.

If people aren't keeping their thoughts private I can hear them. I can also see what they're seeing, things like that. Where I'm from everyone knows how to keep thoughts private but on new worlds I'm careful about using it.
