The Shield Islands are a group of islands associated with the waters near the mouth of the Mander. Their place in the history recounted here is chiefly maritime: local galleys could reinforce a major fleet, while the islands also figured in the ambitions of Dalton Greyjoy.## Ships Join Alyn Velaryon’s FleetIn 133 AC, as Alyn Velaryon sailed north along the western coast, the Shield Islands sent galleys to join his fleet when it passed the mouth of the Mander. Greyshield and Southshield contributed three ships apiece, Greenshield four, and Oakenshield six: sixteen vessels in all. Their arrival followed a storm that had sunk one of Velaryon’s ships and damaged three others, making the additional ships a concrete reinforcement as the expedition continued. Twenty war galleys from House Hightower, commanded by Leo Costayne, were also following the fleet.## A Target in Dalton Greyjoy’s PlansThe Shield Islands also entered the conflict as a prospective target. Dalton Greyjoy had gathered hundreds of longships south of Fair Isle and more near Feastfires, Kayce, and Lannisport in anticipation of Alyn Velaryon’s approach. He proclaimed that, after defeating Velaryon, he would take his fleet along the same route, raise his banner over the Shield Islands, and go on to attack Oldtown and Sunspear and claim Driftmark. These were stated ambitions, not reported conquests; the account presents the islands as part of the scale of Greyjoy’s intended campaign.## A Maritime and Political SettingThe islands’ appearance in these episodes links local naval resources to wider contests for power across the western seas. Their galleys joined a royal expedition at a moment when weather had already cost it ships, while Greyjoy’s plan placed them among the holdings he hoped to seize. In the same period, Lysandro Rogare’s influence reached its height when his brother Drazenko married Aliandra Martell and became Prince Consort and Lord of the Stepstones. The account thus situates the Shield Islands within a changing maritime world, but records neither their eventual fate nor any actual transfer of control.
