For 32 years now, one week each summer, the world has come to an end. Behold, Ragnarok: a weeklong battle event, held at a campground in Pennsylvania, whose name references an apocalyptic Norse myth. It’s part medieval history, part celebration of author J.R.R. Tolkien’s books and a dizzying array of people brandishing foam weapons and foam shields. With “storyline battles” straight out of “Lord of the Rings,” fighters take to the field for full contact combat. The sport is called Dagorhir (it means “Battle Lords” in Tolkien’s Elvish language) and its players fight each other with foam swords, arrows, axes, rocks, and shields. Only traditional garb is allowed here. Think tunics, flowing skirts, leather shoes. Some embrace the medieval, while others go full Orc. There’s a deeper sense of shared community that flows through each camp set up here where fighters camp out together sometimes in period tents and cook together. Some of the more established camps host nightly gatherings where IDs and period drinking vessels are both required. This year’s event drew more than 1,800 people according to organizers, a far cry from the 75 people who were there the first time the world ended back in 1985.
