Idea for a scenario unapologetically ripping off The Teeth of God.
Thieves of Many Waters
The town of Olney, Oregon, is like many coastal towns in the Pacific Northwest - small, sleepy, past its prime, population barely peeking over 2,000. It was once a local centre for logging and fishery (for those brave enough to head out into the Graveyard of the Pacific) but now most jobs in the town come either from the local Big Box store, a smattering of a tourist industry or the bottling plant overlooking the ocean. The few kids that grow up in Olney rarely stay.
Some of Delta Green's files are integrated back into "legitimate" databases in the early 2000's and the conspiracy adapts to the new realities of computational policework at the speed of government. When a data management program is finally implemented in the early 2010's, it spits out an interesting factoid: a disproportionate numbers of violent crimes "of Programmatic interest" have been committed by people originating from Olney, including no fewer than five serial killers documented between the years of 1944 and 2012.
When local drug-dealer, Ethan Jacobs, is reported murdered in his Olney home, the case is immediately flagged as federal under the War on Drugs and the pretence of mapping out an Oregon drug-trafficking route through. Of course, the "joint agency task force" is actually Delta Green investigating why so many people from Olney wind up violent criminals and committing Mythos-related crimes. Jacobs was impaled with a pitchfork in his abdomen by a home intruder, who then carried on the assault by picking up some kind of folk art in Jacobs' possession and smashing it, using a shard to continue carrying out the brutal assault. Piecing together the "folk art" reveals it appears to be something Jacobs made himself - a monstrous thing that appears to be a mish-mash of sea creatures...
The source of the Mythos violence in Olney comes from a temple deep in the local cave system. The interior contains ancient cave art depicting men with spears wading out to sea in "whale-hunting" scenes and the floor is littered with interesting, sharp rocks. When kids get bored and need somewhere to get drunk, or where the occasional tourist passes through Olney to admire the nature, they almost invariably gravitate to the cave and pick up a "cool rock". The cave is, of course, a temple to Nodens. Those who spend a great amount of time in the cave, or who pick up one of the arrow/spear heads that line the cave floor like sand, receive Nodens' "blessing" and his mission. In this interpretation of Nodens, he is a "native" god to this world, as opposed to the many powers of the Mythos of extraterrestrial origin - and Nodens wants the aliens off his damn lawn. Piecing together the mythology of the cave stories will reveal many "thieves" being put to death by a giant chieftain and his spear-wielding tribe.
Those blessed by Nodens are compelled to hunt - anything extraterrestrial is their favoured prey, but the impulse is simply to hunt. The "serial killers" from Olney have been targeting, say, Cthulhu cults - Ethan Jacobs was a Cthulhu cultist, for example - or people who have been mind-altered by a Yithian, or possessed by a Shan. In ancient times, the natives of the region waged bloody war with the Deep Ones. But many of them are simply driven to madness by the newfound voice in their head filling them with the primal urge to stalk and kill prey. Ethan was murdered by the middle-aged waitress of the local diner, Meredith Shaw, who bought A Drugs from Ethan and used it in the cave to keep it secret from her husband. When she received Nodens' blessing, she sees Ethan as a monster and flees, later returning with the pitchfork to kill him. The final conflict involves her wading out into the Pacific to do battle with a Deep One that Ethan was communing with, who of course will kill her (and will attack the agents on seeing them).
Ideally, of course, at least one player gets Blessed. Mechanically, Nodens' blessing works as a "trade SAN for clues" mechanic - Nodens wants you to hunt and investigators are just a type of hunter, so investigators touched by his trident will receive clues that help them track their quarry or tell them how to kill it, or see who is being influenced by extraterrestrials, but are also bloody, horrific and unnatural visions that don't feel good inside your head.
