The Brothers Heathcliff and Locke invent a weapon of mass destruction, The Gear. This mechanical disease devours matter, digesting said matter into more of itself. I.E. It is a self replicating machine that uses every living and nonliving thing as a fuel source. A universe is eaten in it’s entirety. In a desperate gambit for more fuel, The Gear invades another dimension, The Godhead. You are a Soldier, unwillingly drafted into a horrible conflict. At the height of battle, a monster is born from the moon. The Gear is unleashed in the Godhead, and now it’s on you to fix it.
