The Game World section, the Character section and the Story section are the trinity of pages that create the story you want to tell with your game. These help you tell amazing stories that challenge your players and entertain them. Without these you might as well just make a card game.
With the character section of your GDM, think about all the relevant details as you are creating the descriptions of your characters. All the character classes and powers, the back stories, the stories in the game, their personality, alignment changes and any other thing that should be included, and a full character sheet.
This may seem daunting at first, but you only need to start with a list of the characters first, and then you can add to this section as time and production permits.
