For Tywin Lannister-Lord of Casterly Rock, Warden of the West, father to Queen Cersei, Ser Jaime the Kingslayer, and Tyrion the Imp, and grandfather to Joffrey Baratheon, the new-crowned boy king-was the true danger, Catelyn believed.  “True enough,” Ser Brynden admitted. “And Tywin Lannister is no man’s fool. He sits safe behind the walls of Harrenhal, feeding his host on our harvest and burning what he does not take. Gregor is not the only dog he’s loosed. Ser Amory Lorch is in the field as well, and some sellsword out of Qohor who’d sooner maim a man than kill him. I’ve seen what they leave behind them.

In his pride, Harren had desired the highest hall and tallest towers in all Westeros. Forty years it had taken, rising like a great shadow on the shore of the lake while Harren’s armies plundered his neighbors for stone, lumber, gold, and workers. Thousands of captives died in his quarries, chained to his sledges, or laboring on his five colossal towers. Men froze by winter and sweltered in summer. Weirwoods that had stood three thousand years were cut down for beams and rafters. Harren had beggared the riverlands and the Iron Islands alike to  ornament his dream. And when at last Harrenhal stood complete............
