Clues will lead them to Arkham asylum, where the once great Arthur Ormond has been sectioned; and to the famed Miskatonic University, where the terrible history of the idol will be uncovered. However, when their main suspect has a bullet proof alibi the intrepid investigators will have to look to their allies as potential suspects...and when the truth of the theft becomes apparent, there will be a race against time to stop countless innocents succumbing to a terrible fate. This scenario is suitable for 2-6 beginner to experienced investigators and should be solvable in one session of between 4-6 hours. The scenario will run more smoothly if investigators have a reason why they would be hired to find the missing artefact and if they have a range of skills including social skills and research skills, as well as more direct skills such as stealth, lock picking and brawl. It’s worth noting that this scenario can be solved without resorting to violence.

For one moonlit evening two weeks later, Arthur was shocked to see the sarcophagus reacting to the moonlight and opening itself. Excitedly, he approached and was delighted to see a statue of ethereal and otherworldly beauty beginning to coalesce inside, forming from nothingness as the moonlight shone upon it. Unfortunately, his excitement soon turned to horror as themalign and alien intelligence within the idol began to invade his psyche and attack his very being. Arthur resisted valiantly, but gradually his mind was ripped away, layer by layer, leaving only a primal urge to defeat this outlandish and horrendous attacker. Grabbing a nearby pair of scissors, he attempted to remove the invader physically; slashing and cutting his own face and eyes in a frenzied panic. Realising Arthur was now useless as a vessel, the being inside the idol abandoned its attack and retreated back into the sarcophagus, to wait for another host. Arthur was found in his study the next morning, mutilated and babbling; a shell of a man, his sanity almost totally destroyed by the experience. Presently, his opportunistic relatives se
