===Declare Details and Unknowns===
Each player gets an opportunity to declare an additional detail about the setting. Players, if you want to see something specific in the game, this is your chance to point it out. 

When you declare a detail about the setting, you have a few options:
* Add a new detail to the setting.
* Declare something specific about one of the details that already exist.
* Change a pre-existing detail to something new.

Potential details can involve any of the following:
* A location
* A person or faction
* A relationship
* A current event
* An important event in the past
* An environmental factor
* A particular item
* A technology

Next, what are the unknowns, the unanswered questions that the characters (and the players) care about? Each player now gets a chance to declare something that is specifically unknown. Phrase this as a question and write it down.

GMs, use these ideas from the players to build your scenarios and mysteries. Try to work them into your existing plans or use them as inspiration.
