Harrenhal

Reigning Lord of Harrenhal: Walter Whent
Heir to Harrenhal: Lucas Whent, married to Morya Frey, third daughter of Lord Walder Frey and his late wife, Alyssa Blackwood
Knight of Harrentown: (future construction and title)

Harrenhal, the largest castle in the Seven Kingdoms, is the seat of House Whent in the riverlands, on the north shore of the Gods Eye. Since the burning of Harrenhal by dragonfire in Aegon's Conquest, however, the castle has become a dark and ruinous place. Harrenhal's holdings are some of the richest in Westeros, claiming vast tracts of green fertile land which reach as far as the hills of House Wode near the crownlands. Harrentown is found near the castle.

Harrenhal has the largest chamber in Westeros, even larger than the Red Keep's throne room. The Crown chose it as the location of the Great Council of 101 AC because it did not know how many would attend, and wanted a hall for at least five hundred lords and their entourages; more than a thousand came. The castle covers three times as much ground as Winterfell and its buildings are so much larger that they can scarcely be compared. Its stables can house a thousand horses, its godswood covers twenty acres, and its kitchens are as large as Winterfell's Great Hall. However, much of Harrenhal has far gone into decay. The Whents use only the lower thirds of two of the five towers, letting the rest go to ruin, and many places in the castle have not been entered in decades. Bats infest the tops of some of the towers.
