A Green Jewel They Must Possess

From publisher blurb: This short investigative horror scenario takes its name from the early 80s animated film Heavy Metal. It's an homage to H.P. Lovecraft as is my own investigative horror RPG The Outer Presence. A green glowing sphere has been found in what was Sumeria. It's both extremely powerful and dangerous. The investigators have a chance to claim it before others can get their hands or tentacles on it. The vast majority of this adventure is system-neutral and includes a random table of character subplots which will be useful outside this scenario.
