The undersea research vessel Fairweather II has not reported back at the expected time to the Pearl Harbor marina. A derelict ship had been spotted adrift not far from the area that was being researched. Authorities have swung into action to figure out what happened. However, what they find when they get to the abandoned boat defies explanation. Bullet holes and spent ammo casings speak to an attack, but gore encased in bioluminescent slime, and marks that could not have been made by anything short of some huge tentacled creature speak to something else entirely. The covert nature of what was being researched out in an empty part of the Pacific is blown wide open, as rumors of sunken treasure, holy relics, and even the lost city of Atlantis circulate. Catching the attention of many a would-be investigator. Players must investigate the empty boat, traverse the undersea depths, ascertain what was being researched, and track down those responsible to get it back. Major events in the scenario: Investigation of a derelict vessel Exploration of undersea temple Tracking down of Cthulhu Cult Recovery of a stolen artifact Race to return it from whence it came before it is too late!
