"Well. That's true."

Muninn snickers.

"Come on, the other door leads to the armoury."

"Ooh, armoury."

Armoury! It has lots of armours. They're very pretty and glint in the wandlight.

Muninn flies around the room inspecting them.

Lots of them! Also dating all the way to the Founding.

And a cat at the end of the corridor, staring intently at him.

- hm.

He circles back to duck under the Cloak and get on Victor's shoulder.

"Norris alert," he whispers. "Time to go."

Mrs. Norris watches him until he disappears from view then hisses and runs off somewhere.

"Ugh stupid cat. Let's go somewhere else—"

She starts walking in some direction opposite the way the cat went.

Yes. 'Away from cat' is a good direction.

There are many corridors and many doors. Dayo looks around for any feline signs then takes a door at random.

It is kind of difficult to hurry while sharing an Invisibility Cloak but Victor does his best.

She waits, ear against the door, for any sounds indicating Mrs. Norris might've found them, but eventually relaxes and looks around.

It looks like an unused classroom. The dark shapes of desks and chairs are piled against the walls, and there's an upturned wastepaper basket—but propped against the wall facing them is a magnificent mirror, as high as the ceiling, with an ornate gold frame, standing on two clawed feet.

Victor looks warily at the mirror. It looks important. He suspects that they shouldn't be near it.

Muninn flies up to inspect it.

There's an inscription carved around the top: Erised stra ehru oyt ube cafru oyt on wohsi. And Muninn... sees something rather unlike his normal reflection there.

He veers off with a startled squawk.

"Muninn? Are you all right?"

"...look in that mirror, both of you, and don't tell what you saw until you've both had a look."

She goes to look, then eeps.

Victor looks in the mirror.

"...what is this?"

He settles back onto Victor's shoulder, but avoids looking directly into the mirror, instead staring up at the inscription.

"Search me," he mutters.

"I don't expect the two of you saw the same thing I did. My—reflection's moving and—holding a red rock—is that the Philosopher's Stone—?"

"Erised stra ehru - no, wait - read it back to front and ignore the spaces," he says. "I show not your face but your heart's desire."
