He giggles. "What was it about?"

"The sea."

"Aw. And I don't have to ask if it was pretty."

"You do not!"

"Meanwhile, I've been flying to the moon! It's nice up there!"

"Really! What have you been doing on the moon? - how fast can you go?"

"Really fast? I wouldn't know how to measure it. I do have to use magic to get that high. But it turns out it doesn't have to be explosions, I can just directly use magic to move. And I've been building a house, of course, what else would I do on the moon?"

"Seems like a good first step. How long would it take you to get all the way around the planet? Or to the moon, I could probably figure out how far away the moon is."

"It takes me about an hour to get to the moon! I could probably do it faster if I really tried, but I've been there enough times that I can make a portal by now anyway."

"Then maybe some afternoon I will calculate your speed!"

Giggle.

"What does your moon house look like?"

"Want to see it?"

"Sure, but you'll have to provide air."

"I promise I was not going to forget air."

Portal!

She steps through.

And on the other side is a broad courtyard, gravel paths winding between slender trees and marble fountains. He hasn't done anything to the gravity, but he's obviously done something to the atmosphere, because there is one.

The dominant colour is pale grey; even the trees and flowers are nearly colourless, just a hint of green lingering in the leaves, a touch of pink in the petals. The restricted palette lends the place an ethereal air, especially in combination with the architectural style, which favours spare lines, delicate curves, and organic asymmetry, and takes advantage of the low gravity to climb in otherwise-hazardous proportions up to otherwise-impossible heights.

"Oh goodness. It has almost the quality of a foggy day without the actual fog, with the grey. - Does low gravity make flying very different?"

"Yeah, it's kind of interesting. I'm not sure if it's more fun, but it's interesting. And as you can see, you don't need to worry about the air."

"I noticed that!" She tries jumping and flares out her wings at the peak.

Low gravity: so floaty! The Emperor leaps up after her.

And she will flap around peering at all the architecture and complimenting the best parts.

There is a lot of architecture. He said 'building a house', but this looks more like a palace, or maybe a small town.

"This is a lot of house."

"I had a lot of room to build it in!"
