Harren Hoare, better known as Harren the Black or Black Harren, was last of the Iron Kings to rule over the Iron Islands and the Riverlands, and the last member of House Hoare to rule. He completed the grand castle, Harrenhal, which would serve to be his doom.
Harren was born to House Hoare, the ruling house of Iron Islands. He was the grandson of Harwyn Hardhand, the Iron King who extended the ironborn rule over the Riverlands from the Neck to the Blackwater Rush.
During his reign, Harren was a vain, bloody tyrant. Hated by those he ruled, he continued the construction of the grand castle Harrenhal, a project that took three generations to complete, draining the Riverlands to finance the building, with thousands of captives from around dying in the quarries chained to sledges or laboring on the towering walls and five huge towers of Harrenhal, cutting weirwoods to provide rafters and beams.
Harren had finally completed his grand castle of Harrenhal, when Aegon the Conqueror landed in Westeros. Harren's tyrannical rule over the Riverlands earned him little love from his lords. When Aegon swept through the region, may of the river lords, led by Edmyn Tully, revolted against Harren to support the Targaryen invader and joined the Conqueror's host. When Aegon the Conqueror unleashed his dragons, who were not obstructed by the towering walls of Harrenhal and roasted Harren and his sons in the tallest tower of the castle, ending his rule and kingdom. Harren's brother was Lord Commander of the Night's Watch when he died at Harrenhal.
