- "Our home, Greywater Watch, is no castle you've ever seen. And seeing it once does not mean you'll ever find it again. For Greywater Watch... moves."
- ―Meera Reed
It is the home of Jojen and Meera Reed and their father, Lord Howland Reed. It is the southernmost stronghold in the North, and as such its rulers have a longstanding enmity with House Frey, who rule the area of the Riverlands on the southern side of the Neck.
Greywater Watch has not been mentioned in the series yet except for large table map showing Greywater Watch Southeast of White Harbor at the war council in The Last of the Starks.
In the books
In the A Song of Ice and Fire novels, Greywater Watch is the seat of House Reed, one of the most loyal vassals of the Starks. No raven can reach Greywater Watch because it is said to be constantly moving.
