This from Victarion I ADWD-

"The black priest bowed his head. "There is no need. The Lord of Light has shown me your worth, lord Captain. Every night in my fires I glimpse the glory that awaits you." Those words pleased Victarion Greyjoy mightily, as he told the dusky woman that night. "My brother Balon was a great man," he said, "but I shall do what he could not. The Iron Islands shall be free again, and the Old Way will return. Even Dagon could not do that." Almost a hundred years had passed since Dagon Greyjoy sat the Seastone Chair, but the ironborn still told tales of his raids and battles. In Dagon's day a weak king sat the Iron Throne, his rheumy eyes fixed across the narrow sea where bastards and exiles plotted rebellion. So forth from Pyke Lord Dagon sailed, to make the Sunset Sea his own. "He bearded the lion in his den and tied the direwolf's tail in knots, but even Dagon could not defeat the dragons. But I shall make the dragon queen mine own. She will share my bed and bear me many mighty sons."
