Because that's the number associated with her legal identity and might come up.

Shrug. Okay. She adds repeating the number to herself in Oahkar into her cycling list of ways to practice the language without getting too bored. 

And then she is provided with a house!

Cool. Do Delin and/or Kamuor want to come see what her power can do when she has more than her own body and clothes to apply it to?

Kamuor will come check it out and take video!

Excellent. 

She visibly relaxes once she steps inside, and then grins and picks a shallowish closet and opens it to confirm there isn't anything in there anyone'll mind losing convenient access to, and then closes the door and opens it again. 

This time it does not open out into a closet. 

This time it opens out onto what can be presumed to be a mountainside. A few meters away is a train station, with tracks leading down the mountain to a city in the center of what appears to be a bowl-shaped valley surrounded by mountains of varying colors of granite that sparkle gloriously in the morning sun. The city itself can be presumed to have steel-and-concrete cores like every other city made of skyscrapers, but the exteriors demonstrate a complete lack of material constraints. Most of the buildings are covered with vertical gardens, but where the plants peek away marble and lapis lazuli and porphyry show through, the exact stone chosen to complement the building's gardens' contents. The gardens themselves are filled with plants native to both Amenta and Earth, with a few she came up with herself thrown in for the heck of it. 

Kamuor gasps in undisguised wonder.

"Wanna go see the city up closer?" 

"I would love to. You had to design all this, right?"

"Yeah. I cribbed some of it from previous designs and some of it from stuff I read about vertical gardens and I did the rest in between language lessons over the last couple days." 

"Is it, you know, structurally sound and all -"

"Oh, yeah, I've been studying engineering since I was--four--so I could make stuff that would work." 

"It's gorgeous. It's so big."

"I can probably do bigger, this is just the best I could do on a few days' notice." 

"You could be the best thing that's ever happened to the planet."

"Sounds about right for the scope of my ambitions." 

"Can it all be - conventionally interacted with? Or do you need to authorize any changes, if someone were renting a place and wanted to replace their fridge... I guess the bottleneck at the closet door could get to be a pretty big deal if you were trying not to do it all yourself."

"I could probably rig something up with connecting the train systems, eventually. It can all be interacted with but if I make something out of whole cloth if it's taken out of my territory in its original form it'll stop existing. So if I make a fridge and someone hauls it out the front door it'll disappear, but if someone eats a piece of fruit I made it won't disappear out of their stomach. Bringing stuff in is fine. I can make stuff act weirdly but if I don't specify otherwise it'll obey the laws of physics." 

"Oh, if you can hook up to the train then there won't be a bottleneck to speak of. - Oh, except I guess reds don't take the train. Maybe you can make stuff act weirdly so you don't need any in here?"

"I probably could. I did back home, but of course I wasn't hosting nearly so many people there." 

"Does that make it harder?"

"I've never had someone die in one before." 

"They're trialing a system in Orvara where they have purples and oranges handle red stuff on careful rotations wearing a ton of plastic, so they don't build up too much pollution."

"Pity they couldn't have come up with that in the first place before any of those poor people got so badly contaminated in the first place, back when your caste system was getting started." 

"Plastic hadn't been invented then. Or really scalable water treatment either, I think."
