You make one up!
You should all know by now that there is sequel's going on in this site, and we've started a new one. but i'm haveing some trouble thinking up a twist in the story to keep you guys reading so here is what you do. Make up a charictor, add their name, what tie in to the story they can play, and what they are like. after about 6 or 7, i'll find my favorite and use it in the story, using it dramaticly. Good Luck!
Example:
Shellie
Shellie is Jack's old wife but they split up a long time ago because she didn't approve of Jack's being a pirate.
She would be smart and bold and says things right at the right moment to make them funny.
