Demons and Why I Won't Summon One For You!

I was asked by a former employer of mine to summon a demon. He wanted real physical proof that magic was real and that I could use it. I tried to explain to him the gravity of the situation, how a demon would most likely want something from one of us in return, that it could possess one or all of us, that any dangerously unpredictable thing could come out of such a ritual.

And I say to you now the same thing that I said to my former boss,

It does not matter which came first,
the demon or the ritual to summon it,
for when a demon is summoned
a demon appears.
