Just a few minutes ago, I came across this list of personality traits. It may help with forming our characters.

It is in three sections as positive, neutral, and negative traits, with each list in a different color. I didn't count but each section must be 100-200 traits.You have to scroll down all the way to the lists because the intro in the beginning is quite long.
