Theon III Greyjoy was chosen at a kingsmoot. His reign was among those which saw the decline of ironborn power over the western coast of Westeros, including House Gardener and House Hightower ceasing paying tribute. Theon III sailed against them, only to be defeated by Lord Lymond Hightower, who revived the practice of thralldom in Oldtown long enough to set the ironmen captured in battle to hard labor strengthening the city's walls.
