Moat Cailin

Moat Cailin is an ancient stronghold of the First Men on the northern edge of the great swamp known as the Neck, in the south of the north. It is less than twenty miles from the headwaters of the Fever River. This castle is one of the north's most important strongholds, though much of it now stands in ruins. It commands the causeway, the safe route for armies to travel through the swamps of the Neck.
