Veiled Prophet
Actually, the full name is “Mystic Order of Veiled Prophets of the Enchanted Realm.” It’s more commonly refered to as “The Grotto,” a fun club for Masons, but with lower dues and less-stringent membership requirements. The character on the pin is Mokanna, the Veiled Prophet of Khorassan. The white things projecting from either side of his head are not Viking horns but the two halves of a veil he has pulled away from his face. The Nava Grotto is located in Attleboro, MA.
