Yes, subsequent stamps also work!

Woohoo! No more copying that one anymore, not that it isn't already burned into her brain. More to the point, any future diagrams only need to be done perfectly once. 

Next step: swap out the number in the incantation from "sixty" to "eighty". Holding all else constant, does this produce consistently or intermittently hotter water?

It never goes below eighty and the variance is less, but it varies a bit along the same dimensions.

This magic system demands a lot of precision going in for a relatively noisy result coming out. Maybe controlling for environmental circumstances really carefully will be instructive. Does playing back a recording of an incantation work like reciting it?

Nope. Does nothing and doesn't use up the inscription.

How about reciting the incantation loudly vs quietly? (This was such a good pick for first spell; it has a really easily measurable effect size!)

Volume makes no difference alone, but if she actually whispers, unvoicing all the voiced sounds, then it doesn't work (whether this uses up the inscription depends on whether she started any properly pronounced words before switching to whispering: if she whispers it all, the inscription is still usable, and if she whispers only some, the inscription is used up but nothing happens).

She never tries whispering only some; too much risk that it counts as "stumbling over the incantation". Whispering the whole thing is kind of scary, even.

Too many nights in her room doing science is going to drive her crazy; she goes to the Avalon again for longer than it takes to renew her books and looks through the history section again. Is anyone else browsing today?

There's an older centaur fellow looking at the art history selection and a fullformed nixie lady talking to the librarian about getting an interlibrary loan.

Interlibrary loan, huh? That's an idea. But she hasn't gone through the whole nonhumans section here yet. What's in there today? She vaguely recalls a book on Perytons . . .

The book on perytons is still there. There are books on totem animals, a book of speculation about unicorns, books about the sphinx/dragon war, a book about jackalopes, one book about the Loch Ness Monster, books about angels, books about centaurs...

She definitely wants one on the sphinx/dragon war, but not more than one because she doesn't want to associate herself with the concept of dragons in anybody's mind. She'll get whichever of those looks most comprehensive, plus the most comprehensive one on angels and the one about the Loch Ness monster.

Then she can check out The Extinction War and Angelarium; What We Know And What We Don't and Nessie.

Time to go read Nessie on a bench somewhere and get some, if not fresh outside air, at least fresher air than she's been getting. What do actual secret nonhumans have to say about the possibility of one chilling in a lake in Scotland?

There is a Nessie! She's not a species - one-off creatures just exist sometimes. She's an animal, not a person. One-off animals tend to be magical and to have ways of preventing casual observation by humans, but to turned critters Nessie is sometimes friendly. She likes popcorn.

That makes more sense than a person doing it, except for how "one-off species" is almost a weirder concept than magic. What about angels, that sounds potentially pretty weird too. Do they in fact have six wings and enough eyes for the whole class?

Angels are pretty mysterious but do have a lot of wings, "six" being a possible number. They do not generally appear with extra eyes. They don't talk about where they came from, but they are understood not to have "free will" and to instead be bound to carry out tasks, mostly keeping demons in check. They are supposedly incapable of hurting people who don't "deserve it" so a safe way to get un-possessed is to have an angel stab you: you'll be fine and the demon won't. They are genderless, they can glow, bugbears can't sense them, they live a very very long time though they might not be outright immortal, they're eccentric and rare and asocial and sexless and imperceptible by bugbear senses.

That's definitely at least as weird as extra eyes. Margaret has a lot of questions about what exactly decides whether a victim of angelic stabbing "deserved it", but answering those questions empirically sounds 1) infeasible and 2) distinctly not fun. She brings the book on the war back home and reads it there for easier notetaking.

The dragons and sphinxes, the most magically powerful creatures ever unless unicorns (who've been extinct longer) had something cool, had a war. They had allies of other species, but no fully overwhelming dominion over any - most griffins worked for sphinxes, most wyverns worked for dragons, but there were exceptions and the alliances were on the individual or family level, nothing that left the remaining combatants feuding after the sphinxes and dragons had driven each other to extinction. They carefully guarded the secrets of their magical prowess - dragons seemed to mostly use runecasting, but did insane things with it such that it's widely believed to have been a smokescreen for some natural magic in addition to whatever the details were of their incredible defensive prowess; sphinxes relied much less heavily on runes in the moment and tended to have amazingly well-enchanted artifacts in play instead. Some of these artifacts survive and are held by private owners or on display in museums in Europe, the Middle East, and North Africa (where the war spanned). Sphinxes are credited with the invention of medallions and some sort of dispute about dragon medallions is believed to have sparked the conflict, though the historian writing this book believes there must be more to it, as it was so all-encompassing.

So runecasting is kind of sort of part of her heritage, but it's a heritage that nearly wiped out dragons and may have wiped out sphinxes. That's . . . a sobering thought. She'll just have to do better than her ancestors, and not even think about having kids until she finds some way to live openly as a dragon.

Step 1 on that is making some critter friends. Kevin went badly, but that was because they had nothing in common and also she was using him for information. Does the Avalon library, or the Avalon in general, have any events where she can meet other critters her own age? Maybe a book club or something?

If she looks at fliers posted on Avalon lampposts, she can find:

- a book club planning to next read some book called "Nora Finn"
- a video game club inviting all challengers to defeat them at Madden
- a club called Barn Raisers planning on getting together to repair the nondenominational church's roof and clear out some old hippogriff's gutters and refit a house for a harpy family
- two poker nights, a bridge club, a Magic: the Gathering club, a D&D campaign looking for players, and a general board game night
- karaoke Thursdays
- a "Sunshine Day" holiday party for aquatic types and anyone who likes to swim in the Avalon pond
- an after-school club that seems to be aimed at kids who attend school within the Avalon, called "Extra Credit"
- anime club
- street hockey
- knitting circle

"DnD as played by actual magical creatures" is hilarious on a conceptual level even though it's probably very similar to the baseline human kind in practice, and she probably won't have to lie to her parents about anything except the location. She'll sign up for that, provided they don't require nontrivial prior gaming experience--she did a session or two with some robotics club people once, but their group was too large already and she didn't stick around.

It says they're playing 3.5 and the DM can make a character for you if you don't know how, which is probably promising!

She will show up to the next session and meet everyone there and ask for help rolling up a wizard!

"We've got a wizard, do you have a second choice or should I just try to make a real different wizard?" says the DM, who has lop rabbit ears and a rabbit tail on an otherwise human form at the moment but doesn't wear a medallion. Most of the people in this group are older than her, early twenties, but they don't make an issue of it.
