He raises an eyebrow. "On this occasion I did not particularly fear it. if you disagree with the cost-benefit evaluation I'd want to talk it through anyway."

"...that's. Not what I meant. I would not consider it unreasonable for someone to volunteer to take the risk, is what I meant."

He nods. "It might not work anyway. I'm confused by how magical interactions among worlds work in general - ours doesn't seem to have native magic, unless the Ainur themselves were. Summoning as far as you know was initially exclusive to yours, and it worked in Arda only once Valinor was destroyed - were the Valar suppressing it? Did they introduce a loophole when they tried to ban it which unraveled when they were murdered?"

Could you not, Maitimo says to him.

Noted. "I would have expected magic to go by universe, not species, like the law of physics, but that's not what it looks like it's doing."

"Well, daeva magic goes by species. ...I may have completely forgotten to mention parlor tricks to anyone."

"I think you might have," Maitimo says. "Parlor tricks?"

"Humans from my world can do little tiny stupid magic. It is virtually never the best way to accomplish anything, and it can only accomplish very small versions of the things daeva can do - I think the standard use case besides, well, doing a parlor trick to show off that you've mastered one, is to push buttons on assistive devices if you're too paralyzed to do anything else. Sometimes somebody writes a novel where Our Hero is tied up and has to complete a summoning circle by parlor trick or something but it just never comes up in reality like that."

"Huh. Don't think those work in our dimension, if there are books referencing it someone would have tried."

"I mean, they're really frustrating to perform until you have the hang of then and then they are merely somewhat frustrating, but yeah, probably."

And they'll spend a few more days quietly reading the works of the new world.

And: Here is the world!

Cam locates the canal place and makes a drone down there and presently their computers can pronounce Marlese.

Lovely. Drone finding anything else they didn't expect?

"........the animals talk."

"...well. 

We should probably not kill any animals, between them being people and the untranslatable bad thing."

"Yep. I mean, I don't see why we would have done that anyway but yep."

"People who aren't you kill animals to eat sometimes," Maitimo says with a snort. "Does this mean that we could have the drone start chatting and it would just be assumed to be a local talking animal."

"Maybe, unless the computer translation's just not very good."

"Perhaps," Findekáno says, "people will assume it's a foreign bird."

"Possibly. Do you want me to fly this drone to the palace and have it investigate the royalty situation?"

"Sounds reasonable."

So Cam flies the bird (it looks like a small crane) palaceward.

It's not an Elf-pretty palace, but it's perfectly serviceable, very large, surrounded by canals and gardens. 

...a place with talking animals prooooobably won't just let a random bird fly in and look around. What happens if he lands the crane by the gates? Well, what happens is the guard wants to know if the crane speaks Marlese, which Cam answers by saying "tolerably well", and then the guard asks what it wants, and the crane says it is foreign and would like to meet the local royalty if that is at all possible because it thinks they will find what it has to say interesting, and the guard sends a messenger to ask the King if he wants to entertain a random familiar today.

The King (!) and his wife got through most of the items on their seven-page list not within a day of their coronation but within a month, at least, and he's still busy but Iobel's going to be delighted that there's some country using crane familiar ambassadors and he can clear an hour, certainly, please extend him our welcome.

So in goes the crane drone!

"Um!" says Cam to the Elves when he gets a clear look at the King.

The Elves look up and come over to see.
