I put this up ages ago before the board crash and just thought it should appear again. It's a handy resource that I made myself. Basically, if you are creating a character, you need to know the answer to every single one of the following questions to really get an idea of who they are. And you can't say "I don't know" to anything! If you use it and it works, please feel free to show us. Hope you find it useful!
Note: It is written for real world stories and some of the things in it are English so if something doesn't make sense, I'm sorry! Just skip it or ask me what it means or something. It can be altered slightly for fantasy settings.
