Some of them are technically crafting, but that is part of the building (both the verb and the noun).

The day is uneventful, and slowly fades to night.

A much clearer night than usual with the LEDs around the structure.

"It's very strange to have this much light at night."

Shrug. "We can dim them if you'd rather. Might be useful to not attract unwanted attention."

"It doesn't make much difference, at least not up here."

"Fair point. And it's not like it is making the view any worse. Especially in a night like this when you can see the stars-" Thomas starts saying while looking up.

He pauses and squints.

"I think I am recognizing those constellations." He looks for the moon, is the moon visible?

Sure is, rabbit and all.

"...and the moon. Hey, Henry. We are on an Earth again."

"Huh, are you sure? I guess it's a common type of world."

"Yup. The moon looks pretty much the same, and I am pretty sure that is the Orion constellation." He points.

"Huh?" asks Sendhei.

"'Huh?' to what part?"

"What's 'an Earth'?"

"It's the name of a world, or rather a planet that shows up in different worlds. They have similar properties, like similar shape, having humans, having the same sky. My world has an Earth. Thomas was in one before joining us."

"They are bizarrely similar, but with surprising differences, like having different kinds of magic."

"Huh. So you are from a world like ours? And you would know where we are relative to... wherever you were?"

Thomas makes a so-so gesture. "Yes. And In very vague terms? I think we are not too far south, probably not far north. Constellations change over time so I can't be sure."

Henry pulls out a 3D map of Earth on his phone. "Do you recognize any of this?"

"...no. It's... a sphere?"

"Spheroid. But yes. People are pulled down by the force of gravity."

"The force of pulling things down," he repeats, sounding amused.

"And a harsh mistress. Anyway, I guess we should figure out the time period. And where we are relative to everything. Not sure how, but this information ought to be helpful."

"Wait back up though are you implying that we are on a sphere?"

"A really, really big one."
