The door is answered by a small child who says AAAAAAH and slams the door and runs away.

...okay? She waits.

Peeking out the window.

This Elf has black hair in a very intricate bun and is wearing a dark red uniform sort of thing that is awfully pretty for a uniform if it is in fact a uniform, and actually awfully pretty no matter what it is. She has a bag with some weird laser pointers in it and a necklace.

This is an apartment building; the neighbors are also peeking into the hallway. They seem nervous.

Sigh. Next time she will suggest people meet her somewhere where she won't scare their neighbors. She waits.

The messageboard says I believe you I believe you go away!

...okay. She leaves.

Elves will as a rule not report you to the police! If someone were to murder her that'd be super annoying but it still wouldn't get reported to the police! Reporting people to the local police sounds kind of like handing them over to an injured grizzly bear, and that is not an appropriate way to handle real grievances let alone stupid purity-taboo grievances! That said for future visits please have in mind a way for her not to scare the neighbors.

This one person says he lives alone in a little cabin in a ski resort and she won't scare any neighbors if she bothers him.

Great! Off she goes.

He lives alone in a little cabin at a ski resort! He takes a picture of her.

She extends a hand to shake. "Thank you for doing that, I hope it helps reassure people."

...he looks at her hand.

" - oh, uh, where I'm from people shake hands as a greeting." She withdraws her hand. "I don't really know why, come to think of it."

"Huh. Well. ...thank you."

"Sure. It's not a thing anywhere else, we wouldn't - start out with it - and if you don't start out with it it's just dumb."

"If you say so."

She heads back.

Macalaurë summons Kezel. "I need a space station that can house a million people, I have a blueprint, I have an orbit, I need to pay a fairy to get the orbit right -"

        "A million people?"

"You can think of it like a very small moon. With good artificial gravity. The computer model thinks it'll work great and I'm pretty sure that modelling team has demons on it so probably it's already been tested. And if instead something goes disastrously wrong and the fairy decides to stand there giggling about it then my staff will grab my chip for me."

       "Oh, you want to come with while I'm building it?"

"Watching space stations get built is so thrilling."

       "- I'll do it if you sing the whole time."

"Delighted. Can you get Peka's shopping list while you're here -"

      "It's not very nice to summon girls just to get presents for other girls you like better, you know."

"There are two of me who are single, I can take them on a tour of my magnificent giant space station and tell them its creator feels neglected."

      She ruffles her wings and looks at Peka - "where's the list -"

She waggles her pocket everything. "On here, the file is called 'ridiculous indulgences 1'."

"Will all the contents fit in this room?"

"The keyboard might be annoying to move - I think it should go over there - otherwise yep."

All of the things!

She giggles and applauds.

Kezel bows. And then says to Macalaurë - "Okay, where are we headed?"

         "Near where I want it, and then I'll summon a fairy, because in my experience they are not very excited about being teleported."

"Okay."

        He teleports her to a shuttle, teleports the shuttle Hell-Revelation, summons a fairy, teleports the shuttle again to Warp while negotiating. The fairy will put the giant space station in orbit. 

Macalaurë sings while Kezel works. It's three hours' work. He dismisses them both (that, thankfully, can be done out-of-range.) He goes by Stork to pick up the servants he commissioned, follows the fairly tedious instructions in the manual for this station on how to check everything personally and make sure the servants are set up correctly. He heads to Voa.
