House Frey

House Frey of the Crossing is a noble house of the Riverlands. Their seat is the Twins, a pair of castles on each bank of the Green Fork of the Trident that serve as a vital bridge across the river. The strategic location of the Twins have allowed House Frey to amass significant wealth. They are one of the most vital bannermen of House Tully. The current Lord of House Frey is Lady Jeyne Frey.

House Frey dates back some six centuries, making it one of the youngest noble houses in Westeros. The first Lord Frey was granted lands and a noble status, and began constructing a bridge reaching across the Green Fork of the Trident. His grandson saw its construction finished, adding two stone keeps on either bank. During the reign of Lord Walder Frey, beginning 225 AC, the house exploded in size as he and his descendants sired many offspring. He claimed to have hosted three kings at the Twins. Most notable of his rule, Walder colluded with Lord Tywin Lannister to betray the Starks and Tullys in what became known as the Red Wedding. Walder then swore loyalty to Joffrey Waters. Following Lord Walder's death in 300 AC, House Frey became plagued by infighting and rebellion, until they were eventually overthrown by Edmure Tully aided by Aegon Targaryen. The current Lady of House Frey descends from the line of Walda Frey, daughter of Edwyn Frey and Janyce Hunter, and Tywin Frey, grandson of Emmon Frey and Genna Lannister.
