In Tome for Players, you'll get prompts that help you explore your own character in new ways, think about how your character relates to their party members, about the story of the campaign as it stands, and about your own role as a player and what you want to get out of playing the game. In Tome for Game Masters, the questions instead focus on thinking critically about the characters within the game you're running, the NPCs that you've populated the world around the party with, the exciting details of the world itself, and your role as a game master and the things you'd like to experience.
