House Reed

House Reed of Greywater Watch is a vassal house that holds fealty to House Stark of Winterfell. House Reed is the southern-most house of the North. They control the vast area of swampland and bog stretching across the narrowest part of the continent of Westeros, the Neck. The Reeds and their vassals are Crannogmen, a distinct offshoot of the First Men who have adapted to living in the swamps of the Neck.

House Reed's heraldry is a black lizard-lion on a grey-green field. The head of the house is the Lord of Greywater Watch.

Early history
House Reed became rulers of the Neck after King Rickard Stark killed the last Marsh King, and have been fiercely loyal vassals of the Starks since then. Their oath of fealty is distinctive, both ancient and dark, swearing on earth and water, bronze and iron and ice and fire.[2] During the Andal Invasion, the North held out against the Andals in part due to House Reed, who fell on the invaders when they tried to pass the Neck.

Before the War of the Five Kings began, Howland Reed, the current head of House Reed and Lord of Greywater Watch, fought alongside his liege-lord Eddard Stark in Robert's Rebellion and saved his life during one of its final skirmishes at the Tower of Joy.
