"The moon is closer by just enough that they comfortably pass by one another every eclipse."
"...No. The celestial bodies and their associated circles are too hot to comfortably approach, although the moon and moon-circle are much less so than the sun."
"Well, most moons have a wider berth from their suns than 'comfortable' and do not travel on a celestial circle, so it's probably one of those things doing it."
Flight continues. They're already high enough that the pull of gravity is noticeably lessened; the Aluvai adjust seamlessly to the change.
Cam's pretty used to flying in low gravity. It is something of a novelty not to have to make the air to do it with though.
The edge of the planet approaches. Jagged teeth of landscape curve inward from the two halves of the shell. There are various installations visible at the edges - cables strung from one surface to the other across the vast cliff in between, allowing vehicles to be hauled in either direction. The planetary shell is pretty thick - but is it twice as thick as the Earth's crust? Hard to judge by eye.
Well, Cam doesn't have an eyeball understanding of how deep the Earth's crust is either, but this does seem to be a lot of shell.
Everyone pauses, drifting slowly out through the wide gap between the halves of the planet, to check and redistribute their weapons. At the end of this they are each carrying a minimum of one long staff and four wands. There is nothing in sight that looks particularly Enemy-like.
Ah-huh... "Question. If you guys get hit in the wings, do they just sort of magically shrug it off or... what? I can't make full-coverage shield suits that let you fly but maybe your wings just don't - count? Because they're magic?"
"It's unpleasant, but yes, we can easily and quickly replace injured wings," says Azair.
"Right, who wants shield suits and what sorts of shields would they like them to be made of?"
"I'll take the same, if you're offering," says one member of the team.
"None for me, thanks," says another. This seems to be the majority opinion.
"You mentioned something about sending a scout ahead?" prompts Azair, as they take flight again and approach the outer edge.
"Yeah, I'm going to make a drone, but I need to tell it where to go and ideally have open air-or-vacuum between me and it so I can keep an eye on it."
There is indeed a lot of that available, outside the planet. The arcs of the sun-circle and moon-circle are visible off to one side, and there is distant movement almost straight ahead. Another member of the escort points at it; Azair nods acknowledgingly.
"And there is the Enemy."
Cam pulls out his computer and designs a drone, boxed in on six sides with shields... "I never did get an answer about stacked shields. What-all kinds of cylinders have you guys got on hand so I can test that?"
"I want to see if I can make shields all in a stack, one on top of another on top of etcetera, and have them all still work."
"They'll work fine unless the outer layers are damaged by something they don't shield against. So if you have steel on the outside and it's hit with a corrosion blast, there goes your fire shield; but if your corrosion shield is outermost, fire can melt it."
