House Swann of Stonehelm sits on the Red Watch above Cape Wrath, holding the southern marches against incursions out of Dorne. Theirs is a marcher house first and last, and the two combatant swans on their arms, one white and one black, beak to beak, are taken by many as a comment on the temper of the men who fly them.
Lord Gulian Swann holds Stonehelm; his elder son Donnel is heir, and his second son Balon serves in the Kingsguard of King Robert Baratheon. A rare gift, two sons of one house in the white cloaks within memory, and an honour Donnel Swann is said to envy, quietly, when his father is not in the room.
