[Anyway. Kas told me a bunch of things. I think I'm going to visit the moon now,] she says merrily.
And she does.
She is back with the clan in time for her thirteenth birthday, and so is Kas, although he arrives later in the day. Helen waits for him before she bakes and distributes the cake. It is delicious.
After cake, she seeks out Inkeri.
"Sooo," says Helen, "do you remember when we were talking about casting spells on the moon?"
"It turns out that on the moon, 'north' is where you think it is, if you're definite enough about it. If you're not sure, then spells that draw on the cardinal directions just don't work."
"There's a big, complicated explanation full of interesting secrets," she says. "Want to go to the moon and hear it?"
"Yeah," laughs Helen, "I'm not going to take you to the moon and kill you, why would I do that?"
She closes her eyes and listens hard, making sure there's no one else around to see them disappear.
And then—
—they are on the moon, standing next to a perfectly straight arrow scratched in the dust.
"That's one of my north marks," she says, gesturing to it. "I made five in different places, and no three of them point to a single north pole; I checked."
"Yeah," she says. "I'm just - kind of not sure where to start? Um, I'm the Shade-Dreamer's daughter. That's where Kas started when he told me, it kind of explains some things all by itself a little."
"Yes," she says. "That was big secret number one. Big secret number two: she had a lot of magic that isn't anything like witch magic, and she gave Kas some before he left. That's what he used to make me, and what I used to bring us here - it grants wishes, and it's nice about it, as long as you more or less know what you're doing. I would've been in trouble if I'd tried to go to the moon without thinking about air first, but Kas took me the first time and I could just copy what he did after that."
