I had this dream last night that I think would make an excellent roleplay.
Basically, an evil wizard is creating his own pack of werewolves to bully and terrorize people. My character was attacked by the werewolves when he was a child, working out in the fields with his father after sundown. His father sacrificed himself to help my character get away, but he was bitten, so he was turned.
Your character is also a witch/wizard. Your father tried to stop this evil wizard, but was captured. The evil wizard wants to torture him into joining with him. Both of our characters want to kill this evil wizard, which is how they meet up.
My character is male, because I can't play a female to save my life. But the gender of your character doesn't matter. I would prefer a male, but if you like this idea and want to play a female that's okay too.
