Black Ashes Over Greyhaven

The industrial coastal city of Greyhaven suffers a city-wide supernatural catastrophe after an archaeological excavation beneath the old cathedral uncovers an ancient grimoire known as The Book of Thorns. When the book is read aloud during a livestream, a wave of invisible corruption spreads through the city. Within minutes... People begin speaking in languages they don't know. Mirrors show strangers. Dead bodies refuse to stay dead. Buildings become haunted. Entire neighborhoods become "infected." Unlike a zombie virus, the city itself becomes cursed. Inspired by Evil Dead and Silent Hill.
