She can make way better money than busking permits. These concert halls are so excited.

Good.

The Emperor shows up to her third performance. He buys a good seat. No one else recognizes him.

Well, she will hang out receiving admirers after.

When the admirers have thinned out a bit:

"Hello again. Moving up in the world?"

"I decided this would be more efficient."

"I imagine you're right. I'll miss being able to wander by on a whim, though."

"Will you? I'm sorry. Perhaps I'll sometimes sing in the garden anyway, it's a nice garden."

"It is that."

"It's interesting how lovely the buildings and gardens are here when I think otherwise your people care less than mine about everything being beautiful."

"It's easier to be ambitious with the architecture when you can use magic, and a lot of people with powerful magic live in Skygarden. And on top of that, most people putting a building or a garden here will feel the need to compete with the imperial example."

"That makes sense. Many of the nicest buildings in Valinor were put up with magical help."

"Oh? What's magic like in Valinor?"

"My species doesn't have it but our friends the Ainur do. It's very different; it's innately part of them."

"But still good for cheating at architecture, hmm? Just the construction, or can you do impossible things with the end results too?"

"There are a few places where they allowed structures to stand that shouldn't. It's not common unless that's the only way to get an effect, it prevents us from learning more engineering if they do it all the time."

"Well, sure, but building impossible things is fun. —Architecture is something of a hobby of mine, is why I'm curious."

"My world is more technologically advanced than yours, there are things that might look impossible without magic that aren't if you have the right material and process."

"Oh? Like what?"

"Buildings this island could crash into if they stood at sea level."

"You're joking. How?"

"Steel and reinforced concrete frames."

"Huh. Steel buildings, there's a thought."

"The frames. The outsides are usually glass or stone or something pretty like that."

"I usually don't like my buildings to - hide themselves. If I'm building in wood you see wood, if I'm building in stone you see stone. But that doesn't mean I can't put in windows..." he trails off, thinking, and then grins at her again.
