It is pretty and trim and green-and-cream and really ought not to be able to hold itself up like that, and yet here it is, somehow defying the laws of architecture. It is surrounded by a neatly bordered garden of ornamental and useful plants of all sorts: here vegetables, there herbs, there spell components, there rows of flowers.
There is a sign out front. It says only: Magic. Not, Beware, Magic or Magic Emporium or anything like that. Just: Magic.
Sitting on top of this sign is a cream cat with smoke-dark points of color on each paw, his ears, and his face and tail.
All in all, you could be forgiven for thinking that a witch lives here.
"You want to see the Skyvault. I think you're cute, so I want to show you the Skyvault. If you just show up there on a dragon, Mom might decide not to let you look at the Skyvault."
"Oh. And that would be a terrible pity." Beat. "All right, should I call Kexan right now and mix up pancake batter and pack or - I don't know what your questing schedule looks like."
"What party are you calling, please?"
"Kexan."
"One moment, please." The mirror plays soft music and Not-witch goes to survey her pancake ingredients. She picks up a paring knife and an apple and tells the knife, "Peel, core, slice, neatly, then move on to the next, repeat four times," and then she starts scooping large amounts of flour into her giant mixing bowl. "Do you want to chop up the chocolate or something?" she asks Sherlock.
"The other party has not yet come to his or her mirror. Please wait."
"Hmm."
"The other party has not left a message."
"Hmm." She snaps her fingers. "Oh, I remember! Kexan's visiting his uncle, all week. I wrote that down but I didn't think to check my notes. Drat." She flicks the paring knife; it finishes apple number two and then sets itself down.
"Yes, sorry." Notwitch starts snapping her fingers imperiously at all the implements, and they put themselves away. The still-dry pancake mix finds itself a lid and tucks itself into a cupboard. "It looks like it's a hiking trip after all. Will Her Majesty also not let me look at the Skyvault if I arrive not-on-a-dragon?"
"The dragon is not significant. The presence or absence of another member of the royal family is. We are each capable of showing you the Skyvault on our own authority."
"Well, it seems like it would put you much farther out of your way to hike there with me for four days. I have this awful phobia of brooms ever since a temperamental one kicked me off of it, and I'm still saving up to order a carpet to enchant..."
"Do not consider it going out of our way," says Sherlock. "That would imply far too much planning and coordination on our part."
"So when you said you were looking for - no, come to think of it, you didn't, you said Her Majesty wanted you to look for husbands. Ah-ha."
"Let us say that if I were to look into the Pool of Heart's Desire, I do not think I would see a suitable husband looking back at me."
"You know, I do actually know where that one is. The window I mentioned showed me someone who needed to find it, last year. What do you think you'd see?"
Notwitch giggles. "I had a look in the pool once. It's pretty useless to me. I already know what things I want, and it doesn't dispense advice on getting them."
"Well," says Notwitch. "It doesn't give you a complete rundown of everything you want - just the most indispensable heartfelt desire. Which is another reason it's not that practically useful. But since you're curious - I got a picture of me sitting in my study, with Cricket on my lap and a book in my hands - and the calendar displaying a date some nine thousand years in the future."
"Mrrrow!"
"I love you too, Cricket."
