Not really? I'm twelve in Valian years and I don't know if there are things I can't learn because I'm twelve and don't have the brain for it yet compared to if I can't learn them because they have a lot of prerequisites, but it does seem like those're different. 

There do have to be some things, though, because if you turn vampires really young it's a disaster.

Vampire?

(Oliver is quite amused by the string of facial expressions crossing Sadde's and Fëanáro's faces.)

Different kind of Earth has vampires. If you turn into a vampire you stop maturing, and if you turn kids they're - uncontrollable, they have meltdowns that can kill hundreds of people, they can't really be taught and they never grow up-

Oh. So there must be some difference, then. Maybe it's a human thing?

Maybe. No one's tried turning an Elf kid for obvious reasons. 

Could you hire a precog here to see if it would work out okay?

Are they that precise? Legend made it sound like they weren't good at results of experiments - we've got a precog back home too but you have to actually intend to do the experiment for her to get any results -

Not precise, but like, they can know if something will go badly or well, more or less, sometimes?

Huh. I'll suggest it in my letter to them.

Letter? Oh do they use the demon thing to conjure letters from you?

Yeah. But because I'm not a real demon I can't do it too.

What do you mean, not a real demon?

I wished it on, instead of dying in the relevant Earth, which is how ex-human demons become demons, or being born a demon, which is how most demons start existing.

You can wish things? I want to wish so many things, how many wishes can we have, do you have to be near home to wish for things, how big a wish can it be -

You can only wish once, you have to be near a specific world in my home cluster, how big depends on how badly you want it.

...that's a terrible wishing system, who made it?

Evil aliens. Or maybe they got it from somewhere but if so it was a really long time ago and we can't find anything about the creators. 

Evil aliens? Like, they were all evil?

They didn't have emotions and they were harvesting Earth's by tricking teenage girls into taking on dangerous magic so they could fight despair monsters that the aliens had created in the first place. And the teenage girls turned into despair monsters if they messed up or didn't kill enough of them fast enough, so it was - self-sustaining.

Wow that's really evil.

Yeah. A Lúthien got teleported into their world and helped the Bell make a deal with the evil aliens for the wishing device in exchange for Arda mood magic, and the evil aliens agreed, and then they used the wishing device to make their whole dimension and all its neighbors super nice.

What's a Lúthien and a Bell? And can't you export niceness—I guess the technology you can do with lots of demons...

What they can do is wish up worlds so all the dead can come back at a not-overwhelming pace - like, people who just died, right away, but people from thousands of years ago slowly - and there's no scarcity and disease and stuff. And then they screen people for powers they can use elsewhere in the multiverse, and I got being a demon wished-on and some people have resurrection wished-on so you can export niceness but not, like, full-force at the pace that lets them make their neighborhood nice so they're focused there.

Oh. Makes sense. I wanna wish something—but I don't even know what my power is so I dunno what I should wish for...
