The Enclosure was the devotional heart of the city of Juniper. It was an enclosed park with pine groves and featured the headquarters of the Custodians. Above it, high on the southern ridge of the nearby Wolander Mountains, was Duretile, the palace of the Duke. Underneath the Enclosure was the famous Catacombs, where the remains of countless Juniper residents over the centuries were interred.
The homeless man Asa regularly took pine wood from a grove in the Enclosure to keep the fire in the Iron Lily tavern burning. The Lily's owner, Marron Shed, believed the Enclosure was tacky and threadbare in appearance during his adult years, whereas in his youth it was park-like and respectable.
