and the location of the Cape of Eagles
The Cape of Eagles is a cape in the riverlands that juts out into Ironman's Bay, pointing the way to the Iron Islands. It is located west of Seagard and is ruled by House Mallister.
The ironborn lost most of the Cape of Eagles to House Mallister during the reign of Torgon Greyiron, High King of the Iron Islands, and the remainder was lost by his Greyiron successors.
