Harren the Black of House Hoare ruled the Iron Islands and the Riverlands for forty years, which is a curiously long reign for a famously cruel tyrant like him. How did he manage to keep his crown for forty years? If Aegon Targaryen and his dragons never invaded, what do you think would have become of House Hoare and their kingdom? Would they continue to conquer the Stormlands after finishing Harrenhal or would they conquer in another direction? Would Westeros become an ironborn empire instead of a Targaryen one?
