House Reed of Greywater Watch is the chief of the crannogmen, the small green-clad folk who live in the bogs of the Neck. They are First Men of an older First Men than most, having taken less Andal blood than any house south of the Wall, and they keep the Old Gods with a devotion the Starks themselves would call fierce.
Their seat moves. Greywater Watch is built upon a great crannog of woven reeds and rafts, and the swamp shifts beneath it from year to year, a fact that has frustrated more than one army that came north looking for the Reeds with banners flying. Lord Howland Reed rode with Eddard Stark to the Tower of Joy and was one of the seven who went up and one of the two who came down again; he has not been south of the Neck since.
