During my years of roleplaying, I’ve noticed that though you may have a clear image in mind of what your character is all about, filling out a form like this and adding it somewhere for you to be able to read it through when needed is a huge help. Not to mention that it’s an easy way to keep track of character development.
This is the base I’ve been using for as long as I can remember. Naturally it varies from one character to another; depending on if they have something ‘special’ about them that needs its own title; but the basic idea still stands and when laid out like this, it’s easy to modify to serve your every need.
The base sheet is under the cut and I hope you find it as useful as I do.
