Yup. Only direct skin contact really does it, but the twins try to be careful so they hand out each medallion in turn to be tested and then rejected when they don't work.

Do any of these work for Sadde?

...no.

Too bad. Sadde will have to make do with merely being the hot reincarnation of the most powerful sorcerer-slash-sphinx of all time.

How about Temple?

Well, Temple tries a bunch of the "non-special" medallions as Felix hands them to him, then after a dozen of those he asks Felix to bring in the special medallions box.

Sphinx is the first medallion from that box that Temple tries. It doesn't work.

...but the dragon one does if those scales, claws and wings are any indication.

Temple passes out.

Well now he has a Sadde around him. "Temple?" he asks, unsure whether he should shake him or what.

The dragon's eyes open slowly. "Hmm?"

"Some people find their first transformation tiring," Fenris says, "but I've never heard of anyone passing out."

"Well he's a dragon—Temple you're a dragon that is so cool!"

Temple still looks tired but perks up. He raises a claw in front of his eyes. "I am a dragon!" He grins - gosh those teeth look pointy. "This is so cool!"

"And dragons are supposed to be very powerful! I don't actually know what they are supposed to do, but they could fight sphinxes."

He pouts. "Why am I not a mythological animal?"

"Aw," Felix hugs, "maybe we don't have medallions for your kind."

"Poor Sadde," Temple says hugging them both with a scaly arm.

"Ow, careful with the claws."

"I wanted to be a cool animal, which cool animals are even left?"

"Honestly, I think we would need a book to check. There are a lot of critters. Did they have a thunderbird medallion?"

"They did, it was in the special box." Felix squeezes Sadde.

"It's okay Sadde. I shall master magic and create you a new and super-cool form. It will have wings, multiple heads each with a different breath weapon." Temple carefully pats Sadde's head.

He sighs. "At least I'm the most powerful sorcerer ever."

"What a terrible consolation prize," Fenris says, then he kisses Sadde.

"I know, why couldn't I also be a magical mythical creature and maybe a magical girl, too, to boot."

"Excuse me, I think we already established that I am a magical girl. And I didn't even have a cool transformation... until now. Speaking of which, how do I go back being less scaly?"

Felix walks him through the mental exercises.

He pouts and waits.

Eventually, Temple de-dragons!
