Hello! I was pointed to this thread and all I can say is I would love to join. Would the character of the Pied Piper work? I thought that it could go several ways to work him in since he's not traditionally thought of in the fairy tales (his own story far more of a morality tale than most others). My first thought is that his ability to manipulate the mind is something he can do without the flute and it works on everyone. He can't use it to cause people to permanent harm themselves, but he can even charm the sorcerer to at least leave him alone. Because of this, he was strictly neutral in the first conflict. And he immediately knew who he was in the second he reincarnated. Instead of trying to gain power, he went the other route, watching as others began to realize who they were, but also establishing a neutral ground - a bar, of course (in this idea, think of him as the Blood King/Trip from Lost Girl). I really like that take, but I have more if you'd allow - like Trip, I also thought maybe he somehow sets the "rules" for the new generation to keep the public from noticing them, etc. After all, his role in the story was all about justice and following agreements, even if it was brutal.
PM me and we can discuss further. I'm really excited!
