Review the setting
Once you've gathered for the first session, ask everyone to take 10-15 minutes to read the Setting Overview handout. Do so even if everyone reviewed the handout in advance. It helps to refresh memories and get everyone on the same page.
When everyone's done, ask the group what questions they have. Answer to the best of your ability, inviting others to help. Note that some questions (like, "Where did the Forest Folk go?") are mysteries that can only be answered in play.
Ask everyone what they find intriguing or exciting. What catches their imagination and makes them want to learn more? Take notes! Be sure to include these topics in the game.
