Okay, so that's probably just the thing she says not counting as an incantation, or something.

Now she can try recharging diagrams! The diagram she uses for disenchanting already has a reasonable set of rune meanings, conveniently. Her first incantation attempt is "Recharge the diagram on top of this one, make it usable again." 

Nope.

How about a new digram, with meanings light, control, and reverse, and the incantation for making a rock glow with "and also recharge this diagram so it can be used again" tacked on the end?

Nope!

She's not sure how much clearer she can make these incantations. And those red pulses of light from her magic-detecting rock are a bit unnerving in their implications. Hmm, what if she does a normal ordinary "make a rock glow" spell while trying to do unspecified dragon magic at it?

The new rock does not glow.

Wow, she was not expecting that to work without a more precisely specified intention. So dragon magic does or at least defaults to a fairly narrow thing, and that thing is magic suppression, and it can suppress the effects of messing up a spell without her deliberately trying to, which is extremely fortunate. 

Hmmm, what if she it again and consciously only tries to suppress the fact of the diagram being expended, while permitting the actual effect?

That doesn't work; depending on exactly how she concentrates on it she can get the spell to go off, or the diagram to be unexpended, but not both.

Yeah, that was a long shot. At least it's cool that she can fail both of the plausible ways rather than getting the same result every time.

She visits the Avalon library again, looking for anything on species-specific natural magic, especially healing.

Some people say angels can do that. It's also a reputed ability of sphinxes.

Figures that it would be a probably-extinct species and a very hard to find one. Not to mention that a member of either species might turn out to be hostile to her for inscrutable reasons. She texts Bella:

I looked up creatures with natural healing. Bad news: it's sphinxes and angels. I don't suppose you've made any sphinx or angel friends on your travels?

I can't say that I have. You're going to have to redesign the spell anyway to compensate for not knowing all the Arabic, right?

Yeah, but I probably still need someone who can heal. Maybe I should try a sphinx- or angel-finding spell, I know magic understands critter types from when I was checking which of my parents is a wyvern.

I mean is there an obvious reason you can't rework it so it can suck the magic out of a healing rock or something?

I guess I could try that? I expect if that would work they would have done it that way to begin with, so they didn't need to have specific people on hand. Also, of all the places to experiment with something new, the healing part of a medallion is one of the scarier ones.

I'm not sure we should assume they had a goal of scaling up production so they wouldn't need specific people on hand, it could have been a sort of IP thing.

Maybe, yeah. And populations were smaller back then.

It's still weird that Bella would suggest changing something in an unfamiliar spell without trying to do it the original way first. Which reminds her of a different weird thing about Bella.

I have another question, but it's kind of nosy.

Yeah?

So, when I went to give you the teleport, I scried ahead to make sure you were alone and interruptible. But the first time I tried you weren't, and I accidentally saw you getting a tattoo of an invisibility diagram. And my question is, why invisibility? 

It's not my only one. I'm getting a few different emergency ones.

Okay. I would have gone for healing and your phasing-through-walls thing first. It's smart of you to be prepared.

And with that she exits the library and returns to translating.

Bella doesn't seem to have anything to text her about for a while.

Then eventually:

I have a translation! Except for the two weird bits I mentioned it all makes sense. Want me to email it?

Sure, I'd be happy to look it over.

Okay, emailed.

Margaret gets out her dragon magic detector and her coordinates-finding diagram. She's just not willing to try changing things in the medallion process without at least trying to avoid it. Sure, she can apparently suppress unwanted magic, but there's no guarantee that applies to effects that wouldn't kick in until someone started using a thing she made. 

Also, much as she hates the fact, if her winged lion friend doesn't want her looking for sphinxes, that's kind of a reason to look.

First, as a proof of concept, she asks for the latitude and longitude of the nearest dragon.
