Margaret Peregrine is a high school sophomore. Most of the time, she's either at school, at the school robotics club, at the school chess club, or doing schoolwork. Today, she's cleaning out her late great-grandmother's attic.
Then home and try to get on that secretive website again as soon as nobody else needs the computer. She really hopes Kevin remembered the password right.
Oh wow. Oh wow. Notebook time: what do they have for general overview stuff? Is there a page with a comprehensive list of species? Is there a page on what secret magic people scientists have figured out about how it all works?
Figures that they'd have a culture of not making lots of information available. Can she at least see what species pages there are to put passwords into? And do any of the events have clues in them, like "flying race: pegasi and phoenixes welcome" or whatever?
Perytons? Bugganes? Maybe her taste running to lit fic over fantasy really is a problem. She pulls up a dictionary of mythological creatures in another tab and starts looking up the species she hasn't heard of. Is anything mentioned sufficiently reptilian that she can show a scaly claw and claim to be that? Because it looks like she's going to have to go to an Avalon in person to get any kind of science books.
And are wyverns the kind with front legs and wings, or the kind with back legs and wings; it wouldn't do to get called out on transforming the wrong appendage.
She hides in her room and practices turning one foot into a dragon foot and back. She practices saying "I'm a wyvern" and "I like this form a lot better, it's what I'm used to." (The second is a bigger lie than the first; the only thing about her dragon form that isn't awesome is the need to keep it a secret. And the inability to hold a pencil.)
She deletes her mediocre young adult short story; it's more risk than use at this point.
And the following Saturday, she tells her parents she's going to spend the day in the park and goes to the alley next to the abandoned movie theater.
"The Avalon. Where the people without medallions live and the people with them go to visit."
She sticks a hand in it. "I know about pegasi and perytons and bugbears and stuff. What more do you want?"
