House Frey

House Frey is a noble House of the Riverlands in A Song of Ice and Fire and ''Game of Thrones. ''Though the franchise is famous for having mostly morally ambiguous characters and factions most of House Frey is villainous, having been the main perpetrators of the Red Wedding, one of the greatest atrocities in the series. However, there are some likable Freys.

History
The Freys were founded about 600 years before the series began, when a petty Lord built a bridge over the Green Fork. Eventually the crossing was expanded into twin castles, one on either side of the river, hence the Frey's seat of power is known as the Twins. The Freys also use the title Lord of the Crossing.

The current Head of House Frey is Walder Frey who at the beginning of the series is 89, and has been married seven times. He has over a hundred descendants, trueborn and bastard-born. For his 90th nameday Walder Frey takes his eighth wife, Joyeuse Erenford, who is over 70 years younger then him.

War of the Five Kings
When Tywin Lannister attacks the Riverlands Walder Frey doesn't answer his liege lord Hoster Tully's calling the banners. After the death of Robert Baratheon the Lannisters usurp the throne through Joffrey Baratheon. When Robb Stark marches south Walder Frey refuses to let his army across. He claims he would be breaking oaths to the crown by fighting the Lannisters, even though when the Tullys first called him Robert wasn't dead so Walder wouldn't have been breaking his oaths. Robb is forced to make terms with him, agreeing to marry a Frey and betrothing his younger sister Arya Stark to one of Walder Frey's sons, Elmar. Two of Walder Frey's grandsons, Big Walder Frey and Little Walder Frey, are sent to be fostered at Winterfell, and Walder Frey's 18th son Olyvar Frey becomes Robb's squire. The Freys join Robb Stark and later proclaim him King in the North with the other Northern and Riverlands nobility.

When Robb attacks the Westerlands Ser Stevron Frey, Walder Frey's eldest child and heir to the Twins, is wounded and later dies in his tent. This means Stevron's eldest son, Ryman Frey, becomes heir.

When Stannis Baratheon is defeated at the Blackwater by Tywin Lannister and Mace Tyrell, the Freys at Harrenhal with Roose Bolton fear Robb will lose the war and try to find a way out. Later they receive news that Robb has broken the marriage pact, marrying Jeyne Westerling to protect her honor after taking her virginity. The Freys leave Robb's cause. Olyvar Frey wishes to remain with Robb, but is forced to leave by his kin.

The Red Wedding
The Freys agree to join Robb again if his uncle Edmure Tully, Lord of Riverrun, marries Roslin Frey, Walder Frey's daughter by his sixth wife. However the wedding is a trap. At what becomes known as the Red Wedding, Robb Stark, his mother Catelyn Stark, and most of their army are murdered by the Freys and the Boltons.
