A Song of Ice & Fire: Stark Tully Sworn ShieldsThe great Houses of Westeros had many other, smaller Houses that paid fealty to them. These bonds could be quite strong, reinforced by marriage. When House Stark sent out its ravens to call their Bannermen, House Tully was quick to lend their arms to the cause.
