Hard cover adventure for Vast Grimm. A cinematic sci-fi adventure great for new and experienced GMs. What is Vast Grimm? Each miserable day that passes the Universe inches closer to its inevitable demise. Vast Grimm is a Rules Light RPG where everyone must band together in order to keep humanity alive. Most of humanity has either been infected by parasitic wurms, turning them into The Grimm, or is already dead. Those whove survived band together in Legions. In Vast Grimm players take on the role of Legionnaires. Maybe they want to fight back against The Grimm, maybe they just want to scavenge to survive another day, or perhaps they believe the rumors that a Gate of Infinite Stars is being constructed and their Legion may just escape this hellish verse yet!
