"What is the local definition of 'gravity'?"

"The force which pulls stuff down?"

"And it does this in a way that evens out air temperature?"

"Yes.  There's about the same range of mostly human-friendly temperatures even very far down.  It's part of why universal warming could have been such an issue and we had to spend the Age of Cancer learning how to avoid it."

"Huh. Gravity in my world is not like that, it just pulls everything toward everything else proportionally to their sizes, dropping off with distance, and it's a sizable force near a planet but can be overcome with sufficient applications of other phenomena with their own opinions about where things ought to be."

"It would be even stranger if our versions somehow worked more similarly, don't you think?"

"Our version would certainly make an infinite cylinder rather difficult!"

"One would imagine!"

It really is a view.  Also as they go further south the apparent phase of the moon changes from about first-quarterish to nearly new.

"- how's the moon work?"

"Half of it's lit up, half of it's not, it spins a little every day in addition to spirographing around half a step between the path the sun follows, and as it arcs over the surface it stays pointed at the North Pole.  The new moon as seen in the north is on the first day of every month."

"Gracious. What a way for a moon to be."

"I suppose so!"

After they're past the edge, Felicity peers out at the view below before near-immediately retreating back to the center of the shuttle.  It sure is a long way down.  Also the sun is over there, to the left, looking nowhere near as bright as the one Cam's used to, as well as being more uniform and pale in color.  There are plenty of natural caverns, although fewer than showed up on his model when accounting for scale.

. . . One of them has a fair bit of smoke coming out of it.

"- two questions, one, are you scared of heights, two, do people sometimes already live in these caves?"

"One, looking that far down while inhabiting bodies will probably take some adjusting to but hopefully not be a long-term problem, two, not as a common phenomenon?"

"There's smoke in that one. Also I was expecting more caves but probably some of them were the magical material failing to materialize." He approaches the smoke cave.

Felicity reapproaches the window and firmly plants all four of her hands around it.  ". . . Interesting.  I suppose it could somehow be naturally occurring?  Which of course would still be quite important to investigate."

"Yeah, if things spontaneously combust in there that's needful to know." Fly fly.

The burning object seems to be large and made of colorful fabric.  After a bit of fly-flying a figure becomes visible and starts waving its arms wildly and jumping around for a few minutes before sitting down and - maybe having a coughing fit or something?  It's hard to tell from this distance.

"- maybe he got stranded and it's intended as a signal flare!" Zoooooom over to the maybe-stranded.

"Oh no!"

There's enough room in the cavern to maneuver around the fire and land without cutting too close to the strandee, who's watching the shuttle and wearing oddly clashing clothes.  Including a pair of shorts over some jeans.

Cam pops his head out of the shuttle once it's settled. "Hello there! D'you speak Latin?"

He holds his index finger and thumb about a centimeter apart.  "Some?"  And then he tries a sentence in a foreign language.

"Felicity, do you have whatever that is?"
