White Harbor is the smallest of Westeros' major cities, but the largest settlement north of the Neck. It is located on the mouth of the White Knife, the principal river of the North, and is the seat of House Manderly.
White Harbor has much more contact with the south due to its position as the North's primary trade port, and there are more knights and followers of the Faith of the Seven in White Harbor than anywhere else in the North. The city has access to very good fishing grounds and is also the home of many silversmiths.
