From the introduction:
You are the greatest adventurer of all the realm.
At least you tell yourself that.
You have just returned from an epic quest, and have retired to the tavern to impress the locals with your tales of your exploits.
You and your party are telling the story together, but it’s your job to play yourself up, and write your friends out of the story to the best of your ability. If you contradict each other the locals will start to doubt anything you say.
Don’t bash your friends, but you could always lead into the story of their downfall and watch them flounder.
