The Seven Mysteries of St. Fiachra's

My group's usual DM seems like he could use a break... been brainstorming something to run... which is this:

A sleepy little coastal town in Newfoundland - and yet:

1. St. Fiachra's elderly population (these days most of its population) exhibit remarkable health! Locals attribute this to its spring-water - and in fact a health spa fed by St. Fiachra's spring operated on the island until the '80s - but outside reporting tends to claim that their diet rich in fish and seaweed is to thank for this.

2. Befitting a town founded by Irish immigrants, St. Fiachra's is awash with fairy-lore. Big circles of mushrooms sprout across it, said to be portals to the otherworld. In a darker vein, the town is rumoured to be haunted by a fetch, a sort of doppelgänger who appears to people before dragging them to hell!

3. St. Fiachra's high incidence of reported strange phenomena like lost time, astral projection, lights over the ocean, and crabs doing un-crab-like things has attracted a stream of aficionados of the weird over the decades - spiritualists and Forteans a while back, nowadays more UFO-seekers. They congregate in a bohemian flop on the edge of town, and tend to get on the locals' nerves.

4. The people of St. Fiachra's practice their own peculiar sect of Christianity, which among other things rejects the book of Revelation, and instead teaches of an eighth day of creation when God will restore the garden of Eden and return humanity to our prelapsarian glory. The whole town has been under an interdict from the Catholic church for over a century!

5. Visitors to the town often report being frightened by noises that seemed to come from underground. Locals joke that these noises are made by the sluagh na marbh - the "host of the dead"!

6. The region around St. Fiachra's has had one of the highest disappearance rates in the province in 2025. The latest & highest-profile of these disappearances was immortality-seeking multimillionaire Johnson Bronson.

7. The sole exception to the town's otherwise-impeccable health - a disease of yet-unknown cause has been spreading in St. Fiachra's. Symptoms vary, but tend to include lethargy and confusion. The disease's spread has coincided with a spike in xenophobia in the once-tourist-friendly place, problematizing its study. The prevailing theory is that it is something like Minamata disease, caused by contamination of the town's fish supply by the nefarious communist Chinese.
