Yeah, checking - he runs through attempted teleports - but while we're here we could solve all their problems, probably. 

Really?

Humans - die of a lot of stuff? I have cures for most of it. And they have people who go hungry and stuff -

Oh. That sounds good if you know how, I don't know hardly anything about the mortal world, I only made this portal for the mortal I found a long time ago.

Not all humans are alike and not all human worlds have the same problems but this one looks pretty advanced and is plausibly advanced enough I can just teach them a lot of science and cure cancer and malaria and the like?

Maybe you should check if it's adjacent to anywhere you know first.

I'm checking. He's about halfway through.

Promise waits.

They are not adjacent to anywhere in the peal. Should we stay here and fix stuff while we think of better ways to fix your home world?

...we can commute to my tree, right?

Of course.

Sounds good.

Cool. Scale model of the world - oh, it's an Earth, that'll make it even easier - especially if it's a no-magic Earth -

How does that help?

I know, like, which countries have basically decent governments and which problems will need solving and stuff - also Earths often have Bells, let me check -

- this Earth does not have a Bell -

- nope - none of us, either - but we can go put everything on the Internet if we don't want to be disruptive or go land a spaceship on the White House lawn if we want to be disruptive and basically expect people will put the knowledge to good use.

I don't know what the Internet or spaceships or White House are.

Internet is a way for everyone in the world to talk and put books and other things they know so everyone can access them. Spaceships fly through space between worlds; if we land in a spaceship the humans will assume we are aliens from another planet in their dimension and there are various social assumptions about what to do about aliens so they'd probably give us a parade and be excited to have our technology. The White House is the place where the economically biggest country on Earth houses their government. We can also bypass all the grownups and just do everything.

...grownups?

...people who've reached developmental maturity? Do fairies just start out grownup like new Arda species or something?

Most kinds of fairies do. I know what a grownup is but I think I probably qualify as one and it seemed like a strange category to refer to there.

Bypass governments, then.

How do those work, anyway?

Everyone decides who should be in charge and then those people get together and run things? Ardas are usually monarchies - that means you decide once and then that family's in charge forever - and Earths are mostly democracies - that means you decide again every few Earth years -

Fairyland has a Queen but she's the Queen because she knows everyone's names.

How does she do that?
