The Neck is a region of Westeros covered in swamp & bog. It divides the south of the continent from the north. There, one can find huge flowers, lizard-lions & many snakes. The trees are half-drowned, covered in fungus & beneath the water, quicksand that will drown anyone who attempts to walk the waters. The Neck is considered the key to any assault on the North. The region is inhabited by the crannogmen ruled by House Reed.
