I think she will probably have guessed the broad strokes and prefer we go light on the details.

Yeah okay that makes sense.

Snuggle.

Snuggle!!!

More artefact-staring occurs over the next few days. He continues to think Edie is wonderful and to allow her in his mind, and he'll share the magic sense with both siblings whenever they want to and be particularly excited whenever he manages to crack this nut a little more and advances in his understanding of how this artefact works. The fact that its wielder is willing to answer questions and explain some of its properties helps a lots, too.

The wielder continues to be taciturn about anything that touches on the shit that happened to her that one time but is otherwise entirely willing to answer questions and explain things.

It doesn't take that much longer before Edie finds a sorcerer named Horace Rockwaller who's willing to activate and train him.

Cool! (And finally!)

Horace Rockwaller is a boisterous old man who is so!!! Enthusiastic!!! About magic!!! And has been informed about Kaede's metamancy powers and is so, so intrigued by the possibilities they represent!

Awesome! When do they meet?

Tomorrow?

Sounds good!

Would she like to meet in a public place to start out with, or come to his home/workspace?

Whichever he's more comfortable with, she's not picky.

He gives her his home address.

Will Edie give her a ride? She's been using her mana spell often enough that she has more mana than she's ever had at any single point in her life before.

Edie will absolutely give her a ride.

Eeeeeeeeee best girlfriend!

This is ambiguous, at least when Kaede is also a girl! She will not deny it at all when Kaede is a boy but that time is not now.

Kaede thinks this is the sort of thing that's symmetrical? They are probably both the best girlfriend when she is a girl.

Makes sense.

So: best girlfriend!

And then they're there.

Horace Rockwaller is just as boisterous in person as on the phone!

"Hello!" he says in a deep, booming voice. "You must be Kaede."

"I am! It's good to meet you."

He grins. "It is wonderful to meet you as well."

She beams. "May I come in?"

"Of course, of course," he says, stepping out of the doorway and holding the door open for her.
