Character, Background, and Plot Generators
Sean spotted a random backstory generator that you may find helpful to fill out the backstory questions on the RSVP form, please find it below along with several other random generator sites that I've collected.
Please don't feel bound by any detail that you don't like, anything you get with one of these tools is just a suggestion and ultimately you should build a character you understand and will enjoy playing. Even better is one that you feel sympathetic too and invested in.
