The Summer Isles are mentioned as a destination in Corlys Velaryon’s seafaring career and as the homeland of a prince who visited the Red Keep. The account offers no broader description of the islands, but links them to both maritime travel and an encounter that reveals Daella Targaryen’s fears.

A destination on Corlys Velaryon’s voyages

Among the routes Corlys Velaryon sailed before becoming Lord of the Tides was a voyage aboard the Summer Maid to Volantis and the Summer Isles. The islands thus enter the narrative within an account of his growing experience at sea: he travelled not merely as a passenger, but learned the work of sailing through repeated voyages to varied destinations.

A visitor at the Red Keep

The Summer Isles also appear through a prince who came to the Red Keep in a feathered cloak. Daella Targaryen, already fearful and easily startled, squealed when she encountered him and mistook him for a demon. The episode records her alarm rather than providing further information about the prince or his homeland.

Narrative significance

These references place the Summer Isles at two different points of contact with Westeros: as a destination reached by a renowned sailor and as the origin of a visitor encountered at court. Together they associate the islands with maritime reach and cultural unfamiliarity, while leaving their geography, customs, and political life undescribed.
