Sometimes as a referee it's really nice to take some of the load off when it comes to planning storylines and plot points for your campaign. Players will often be happy to help you, but figuring out how to collaborate creatively can be just as difficult and time consuming if you don't have structure. Luckily, there is H.A.N.D.S.
Hands will guide you and your group through creating your own F.I.S.T mythos. Past missions, VIPs, and current threats are all things you take turns creating. The prompts given got me thinking about my game just by reading them aloud, so while the Zine itself is meant to create collaborative content, it could also be inspiring for any referee just looking to write their own stories.
H.A.N.D.S is great for session zero or at any point at all. Have fun creating with it!
