Aegon fell deep in thought. While they could probably beat House Lannister, and subjugate the Riverlands, his forces would be too spent if they ever emerged victorious. It seemed that nobody else would join either him or House Lannister. He hoped to defeat Jaime Lannister quickly, take Casterly Rock and hope that the other Lord Paramounts would somehow join him peacefully. House Tyrell would swear fealty to the victor easily enough. But he harboured no illusions about the rest – not all of them would go down without a fight. They couldn't afford to follow the Kingslayer's plan and lose most of their strength in the Riverlands.
