Upon Robert's death, Stannis declared himself king of the Seven Kingdoms and condemned the queen's children as bastards born of incest, as he had discovered with Jon Arryn. Dragonstone became his main seat. He returned there after the disastrous Battle of the Blackwater. His councilor, the red priestess Melisandre of Asshai, tried to convince him to let her raise the "stone dragon" of the castle through blood magic, but Lord Davos Seaworth convinced Stannis to go north to the Wall to help the Night's Watch instead. After Stannis abandoned Dragonstone, leaving the Bastard of Nightsong Rolland Storm as castellan, Queen Regent Cersei Lannister dispatched a fleet to barricade it. However, Ser Loras Tyrell, impatient to free the fleet to protect his home castle of Highgarden, attacked Dragonstone directly. He took the castle but lost a thousand men and was himself reportedly gravely wounded. As of A Dance with Dragons, Dragonstone is now controlled by troops loyal to House Tyrell, and theoretically, once again under the control of the Iron Throne.
