And Cam goes too because he finds not speaking Marlese annoying and even if Fannar can't summon he can teach Fëanáro Marlese and Fëanáro can summon.

They're back in Arda. The Elves start checking their internet workspaces for important notes and projects. Fëanáro wants to solicit more demons to help on the binary-search inhabited-planet-finding process, if there are any that can be trusted with the knowledge of interdimensional travel, if Cam doesn't have any recommendations perhaps he can briefly go back to Hell and put a Maitimo there to try to screen people? Also please give him all languages that are spoken in the dimension they explored.

Maitimo and Findekáno shake hands and head off in opposite directions. Fannar draws a summoning circle.

"All languages" is a tall order what with the literally every human on the planet having one of their own with no written equivalent on top of a human-normal variety of vernaculars. Cam has some loose recommendations based more on professional than personal knowledge but perhaps it would be easier to vet demonized Men or Dwarves than to rely on a Maitimo being able to handle life in Hell where a lot of things are casually radioactive and everyone expects everyone else they meet to be a demon.

There's only a handful of demonized Men and Dwarves so far, since it's been so little time, but letters will be addressed to them. There's a blessing for radiation; everyone expecting everyone else to be a demon might be more of a problem. Fëanáro is really really out of his mind at the thought that every single person has a language. Well, he'll learn as many as he can.

And Fannar's summoning circle works! It produces a racist angel who glares at Cam but accepts a record player as compensation for her time ("can't beat vinyl").

"Speaking of your polyglottalism I want to piggyback on that," Cam tells Fëanáro, "computer translation's great and all but not ideal."

Fëanáro guesses the idea. "Should we tell that poor child to send you home?"

"Yeah."

The poor child had returned to Endore once summoning was established to work and 'making Cam go away forever by killing a child' no longer available as an option. He lives with his parents in Himring; someone calls them up, and he sends Cam to Hell.

Where he waits around a bit.

Fëanáro draws a circle. 

"Yo. Wow that's a lot of languages."

"I've been aiming for one a month," he says. "It keeps me psychologically healthy. Aren't they beautiful? Tell me about the other dimension."

"Your alt hasn't already told you all about it? It's got a you and your whole family and also a me who's bizarrely married to the Maitimo there, and talking animals. The me has an impolite cat."

"He's talking to the third of me, I just got the memo." He raises an eyebrow. "The memo didn't say you were bizarrely married to the local Maitimo...I can see it, actually, in a society that had more functional options for relationships for my son than this one did."

"Uh, the me is actually a girl, if that's what you mean."

"Not exactly. But let's talk about something more interesting, the idiolects. I want to figure out the system that generates them and reverse-engineer it."

"I didn't learn any of them but your alt knows a bunch. And we're going to move some people to their planet to have kids there in case that gets them spirit animals, albeit mostly for spellbinding reasons and not idiolect research but no reason not to combine the two."

"Great. If there are other human worlds out there - and we've found two so far, it seems there might be - is it going to possible to develop a standard procedure for getting them up to speed, or are we going to need to improvise?"

"Improvisation seems unavoidable - different magic systems different tech levels, different cultures, about the only thing that's the same is the biology which means we don't have to reinvent medical science every time. We might be able to set up a sort of tech tree thing where we figure out where they are and what prerequisites they have for what else? But that wouldn't be human-specific."

"Alright. Then there's no real way to speed along the discovery and exploration process.

I am guessing from where the worldleaper sent you that it doesn't actually pick universes randomly. There's got to be some attractors at work and we're trying to determine what they are."

"Yeah, that occurred to us. We weren't anywhere near them - and I think it was luck that let us find their country first, I just thought the canals were cute - but it's weird."

"I mean, it makes sense we'll be ruling the most appealing country wherever you land," he says with a shrug. "But a world that has copies of you - unless most worlds do, and that'd be strange -"

"It's also odd that they were together, that Iobel wasn't born across the globe from the country your family happened to rule."

"Yes.

I really want to get some more worlds and some more data. Want Fannar to summon you first so you can get the idiolects?"

"They're not urgent, but if it's convenient may as well."
