He feels an open summons and lets it grab him -
Casually, he shifts to fullform - yup. He is a blue-grey deer with wings. The peryton summoner sits, and then looks at Cam with big blue deer eyes. It is absurdly cute.
"Pleeeeease?"
"Oh good lord. Stop, I may snap back to Hell from sheer cute overdose."
He snorts with laughter, and returns to being human. "Can't have that! You are a potential medallion factory! I need you. Mind you, if you tell me to buzz off I will, because I try not to be a jerk."
"I mean, as you can see I can make these things pretty damn fast. I imagine I will still have time for other projects."
"True!" he agrees. "But it's not like I can force you to make them, so I might as well be nice about it."
"Then I would ask you very nicely if you would or not, and if the answer was 'no' I would continue my mission of 'trying not to be a jerk' and accept that as an answer and not force you to do anything in particular!"
"Okay then." It occurs to Cam to go ahead and conjure a leather coat, slightly lumpy due to wings but not obtrusively so.
"Also, I'm a scrawny fifteen year old who knows only a smattering of magic and probably can't even manage anything practical under pressure. So you are double safe, not only do I not want to but I'm pretty sure I am completely incapable of it."
"I mean, you could threaten to send me home before I care to go, although as threats go it's kind of lukewarm."
"Pretty much, yeah. Oh no, I could put you back to where you were before I was even involved! Quake in fear, demon, at my powers of mild disappointment!"
"Farish, I do not want people to run into me while I am doing magic. Also if I blow myself up I don't want any casualties aside from the obvious one."
"Eeeeh. No? But magic is kind of dangerous, and it does - things." He motions to Cam. "Strange things. Think of it like chemistry, but combined with - Sudoku, or something. And it can explode or summon someone from another dimension."
"I'm afraid not. I've never heard of extradimensionals before in my life. It might have happened before, because our magical records are hilariously terrible, but I don't think it's common."
"It's also entirely possible that I did a thing that no one else has ever done before! I have no idea! I am mostly self taught, I have no idea what the standards are for magical knowledge."
"Learned the basics of it through surgical use of my peryton sadface, lots of logical arguments, and doing an absurd amount of menial chores. Then from there I used what I knew to find the other - .... I explained it as chemistry and Sudoku combined, right? I worked to learn the other elements on the periodic table and the other numbers in Sudoku. Essentially."
