"I was thinking right after the conference wrapped up if that works for you."

"It will." His eyes flicker. "Yes, all set." And to Findekáno, "are you also coming?"

"Yes."

"I'll see you both tonight, then."

That'll be a fun group to go exploring with. Cam doesn't remark on that. "See you."

They're both there that night, sitting outside the conference at separate tables and desperately delegating the next few weeks' activities. 

Cam can wait while they do that.

And then everyone is ready to go hop dimensions.

So Cam makes a worldleaper and poises himself to produce air and a ship as soon as they land.

And they find themselves in deep space, as was statistically nearly guaranteed.

Air! Ship!

"Are there locals?" both Elves say eagerly in unison, and then fall silent.

"I shall hop outside so I don't burst the ship if the answer is 'lots'," Cam replies, and he lets himself out and starts conjuring up stuff.

Presently he returns. "Humans!" he reports. "Or something that looks a lot like them."

"...huh," Maitimo says.

"That is very surprising," Findekáno says. "Even if we think dimensions have recent points of divergence. Shall we start narrowing them down?"

"Did that," Cam says, "they're that way. I'll narrow it down again when we're close enough to get a look at individual stars in the right galaxy."

"Can we look at what you've got? Do you have translation up and working?"

"Translation needs to chew for a bit, there's a bunch of languages, but feel free to have a look," Cam says, handing them each chip corpuses of recentish recorded output of local humans.

They can't read the writing yet; there are an awful lot of charts and diagrams. This society apparently organizes a significant portion of their written output as flowcharts. 

"Interesting to be in a new place without the advantage of speaking a language," Cam says, laying in a course for the correct galaxy.

"I am surprised my father did not personally insist on coming. Hundreds of languages, huh?"

"...More," Cam says. "But only a few hundred popular ones and a lot of them seem to have very little writing."

"No computers, do they have electricity yet?"

"Can't guarantee they don't but haven't found any evidence of it yet."

"Fastest way to safely tell teach them all summoning is probably going to depend on local government," Maitimo says. "Findekáno, were your people getting anywhere on non-summoning forms of immortality for humans?"

"Getting somewhere, yes, have a serum for Cam to dump on their heads, no."

"That'd be an interesting method of administration."

"More likely in the water supply," he says, "but immortality good enough to spike the water supply with is a much harder problem than immortality as a series of shots administrated annually and we're still in early clinical trials with that."

"These humans might be clinically distinct anyway. Even Earth humans have ethnic variance."
