One Chronicle per Character: Each character can only earn one copy of a Chronicle for any single adventure. You cannot replay an adventure for credit with a character that has already received credit for that adventure.
Notify the GM: Inform the GM that you have already played the adventure or run it as a GM. Although GMs are asked to be flexible, the GM maintains the right to deny running the adventure for you if they feel uncomfortable running the event for players who have foreknowledge of the story.
No Spoilers: When you are replaying an adventure, avoid spoiling the adventure’s plot or using insider information to affect gameplay. Doing so can be grounds for the GM to remove you from the table. In general, be mindful in separating player knowledge from character knowledge, and if you are uncertain how to proceed, speak privately with the GM to determine the best course of action.
