Your role-playing history is your character's biography. Who is he or she? How did he come to Sosaria? What adventures or significant events happened along the way? Who were her parents? The role-playing element comes into play as you tell the story (i.e. using first person instead of third person).

Think of it this way: You are an author who just wrote a play. You have cast yourself in the lead role. Tell the story as if you and your character are the same person and tell it from the character's point of view - not the author's.

Hope this helps.
