PrincessArgella Durrandon was the daughter and only child of Argilac the Arrogant, the last Storm King. After her father was killed in Aegon’s Conquest, she barred the gates of Storm’s End and declared herself Storm Queen. However, her garrison refused to share the fate of Harrenhal and revolted, raising a peace banner and delivering Argella to Orys Baratheon’s camp, gagged, chained, and naked. Orys, however, removed the chains with his own hands, wrapped his cloak around her, and gave her food and wine. He spoke to her gently, telling her of her father Argilac’s courage in death.
Aegon rewarded Orys Baratheon with Storm’s End, the rule of the Stormlands, and Argella. On his marriage to Argella Durrandon, and to honor Argilac’s valor, Orys Baratheon adopted the sigil and words ofHouse Durrandon as his own.
