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