You could probably get away with English, considering.

I probably could, but I'd rather not push the envelope when I'm already pretty good at French. I suppose I should try it the once in controlled conditions just so I know what my options are in an emergency.

If it was me and it worked I'd do it all the time. I guess you want to be able to share, but you can already only share incantations with folks who work in French.

And it's not like I've open-sourced the incantations I have already. I'll give it a try tonight and see what happens.

With an itty bitty rune.

I'll make a tiny version of my spell for making things glow; it's had the least variation in effects so far. And I'll check it over with a magnifying glass.

An adorable mental image.

Bella thinks she's adorable!! She dithers over her response for a bit.

Thanks! I'll let you know how it goes. Anything else we should be figuring out?

Suppose we should worry about teaching licenses and all that jazz?

We should make sure not to do anything illegal since we want to come clean to the humans eventually, but I'm pretty sure you don't need a license to teach people things if you aren't tied into an official diploma program. Maybe if people refuse to learn from us without them?

I think that might depend on how old the people you teach are.

I wish I could ask my mom, she was a kindergarten teacher.

It can't be illegal to teach your friends to knit, right, and magic is presumably less regulated than that, but maybe it's illegal to take money for it or something.

While she's waiting for Bella to text back, Margaret flips through her rune dictionary, looking idly for meanings that might be relevant to aging and death beyond what she used in the healing spell.

It might be illegal to teach a bunch of kids to knit in a formal setting. We could almost certainly avoid this if we just took college students but it's probably not worth as much thought as I'm giving it anyway.

She'll probably just use the healing diagram with a different incantation, then. 

I suppose it depends on how likely anyone is to respond to "magic exists" with "I want to find some way to seriously inconvenience you".

That's the coolest end to a text conversation she's ever experienced, and anyway, she has magic science to do. She starts in on a tiny version of the glowing diagram, realizes it got really late while she was texting, and puts her pencil and magnifying glass aside until the next day.

When she finishes it, she takes an unenchanted rock and a deep breath, holds her dragon magic detector where she can see it, and says in plain English, "Make this rock glow blue; make it emit light without heat."

Pleasantly blue glowing rock. Dragon magic detector goes YIKES.

Well, if she's ever in an emergency with a shortage of both paper and vocabulary words she can still do magic without either harming herself or suppressing it completely, but yikes all the same.

Now it's time to start in on de-aging for real. She orders a batch of tadpoles from a science class supply catalog and checks her web store for any more orders or questions.

She has plenty of orders for medallions and her other offerings accumulated.

Medallions and other things go in the mail, with little cards asking people to leave reviews about anything they liked or didn't like. More medallions get prepped, replacements for the sold ones and a couple more monster species she's had requested.

She sends Bella:

Medallion orders have been picking up a bit. When would be a good time for you to come over and make the next batch?

Also, I tried an English incantation with a tiny diagram; it worked like a full-sized diagram and a French incantation but required dragon magic to come out that way.

Wow. Is there anything we need to just crazily overcast?

I can come over Saturday morning.

Now that you mention it I am tempted to crazily overcast a heal on myself but I think it would be a better idea not to do that. Saturday morning works great!

And then it's just a matter of making healing diagrams and waiting to see which of the tadpoles or Saturday morning arrives first.

A crazily overcast heal seems like the kind of thing that leaves you with six kinds of cancer or a tail or two heads or something.

Yeah, hence the not doing it. And even if I did I would try it on a bug or something first.

Once the tadpoles arrive (twenty of them, and a little plastic setup with fake rocks) the first thing she needs to do is make it possible to tell them apart. Each one gets separately enchanted to glow a different color when poked, and she assembles a file with the hex color codes, a picture of each one glowing, and a space to write each incantation she tries and whether she ended up suppressing it.

Now she has lots of tadpoles who start glowing when she taps them.
