Bordered by the Riverlands to the northeast and the Reach to the southeast, numerous mountains and hills along the border give the Westerlands natural defensive barriers. Ruled by House Lannister from the stronghold of Casterly Rock overlooking the city of Lannisport, the Westerlands is the richest region of Westeros, being home to numerous gold and silver mines.
