I would love to play something inspired by History Channel's-- Houdini. As played by Adrien Brody or inspired by the book Night Circus somehow.
Or: Character A (my character) is a Roma gypsy. He is a tarot card reader who is good at what he does. He's also a pickpocket, a liar, and a thief of carrying degrees, and travels with a carnival from town to town. Character B is a vampire/demon/witch something of the sort who was hunting in the town Character A was doing cards in, he ran into the young gypsy one day and when Character B caught Character A stealing from him, he gave it back, offered a card reading in return. Character B took him up on it and thought nothing of it, till a warning he got from the gypsy turned out to be true and saved his life, and he's been looking for Character A ever since, maybe to thank him, maybe to kidnap him, maybe just to get another reading.
Or again Something involving myself playing a bankrobber/computer hacker or something of that sort. It can, or cannot be based off the character Psi in the Doctor Who episode Time Heist . I'd be up for playing him before the episode when he was a hacker/bankrobbe, when he was in jail, or after the episode's ending. Or something with completely original characters
