Edwyn Frey

Edwyn Frey is a great-grandson of Walder Frey. He is the eldest child of Ser Ryman Frey, who is the eldest child of Ser Stevron Frey, who was Walder Frey's eldest child. Edwyn is married to Janyce Hunter and has one child, Walda. He has a feud with Ryman's second son, Black Walder Frey, who desires to succeed to the Twins himself. They have another brother, Petyr "Pimple" Frey. Black Walder is believed to be having affairs with many of the women round the Twins, including the wives of both his brothers, casting Walda's parentage in doubt.

He is described as being a pale slender man with a pinched nose and lank dark hair. He has a cold attitude. Ser Daven Lannister describes him as being "Not as thick as his father, but as full of hate as a boil's full of pus." However Edwyn is described as being not a man of the sword.

Walder Frey forces Robb to agree to marry a Frey in exchange for his support in the War of the Five Kings. In the Battle of Oxcross Ser Stevron Frey is wounded and dies a few days later, making Ryman Frey heir to the Twins.

After Robb takes Jeyne Westerling's virginity he marries her to preserve her honour. The Freys leave his campaign in anger. Later they tell Robb they'll join him again if his uncle Edmure Tully, Lord of Riverrun, marries Roslin Frey, a half-great-aunt of Edwyn. When Robb arrives at the Twins, he is greeted by Ryman and their sons. Edwyn acts politely and tells Robb his host can take shelter in three tents.

Edmure marries Walder Frey's daughter. When Dacey Mormont asks Edwyn for a dance, he wrenches himself away. Catelyn has begun realising something is wrong, especially when the musicians start playing The Rains of Castamere. As Edwyn hurries for the door she grabs his arm and feels armour. She slaps him hard enough to break his lip, but he shoves her aside. When Robb moves to confront Edwyn, he is hit by quarrels from the crossbowmen in the gallery. The wedding was a trap, the Freys and Robb's treacherous bannerman Roose Bolton murder Robb, Catelyn and most of their troops, taking Edmure and other nobles hostage. This becomes known as the Red Wedding.

Later Edwyn's brother Petyr Pimple is captured by the Brotherhood without Banners. One of his half-great-uncles, Merrett Frey, goes to Oldstones to deliver the ransom. Merrett thinks of Ryman as foolish and of his sons Edwyn and Black Walder as worse, as both intend to throw most of their relatives out of the Twins. Merrett hopes to win the favour of the main Frey branch by ransoming Petyr. However he finds Petyr has already been hanged. Lady Stoneheart, the resurrected Catelyn Tully, reveals herself and at her command Merrett is hanged.

For their service to the Iron Throne, the Freys are rewarded by Tywin Lannister. Walder Frey's second son Emmon Frey, married to Tywin Lannisters' sister, is given Riverrun. A Frey force of 2000 under Ryman Frey besieges Riverrun, which is held by Edmure's uncle Ser Brynden Tully "The Blackfish". They are aided by the Lannisters and the reluctant River Lords. The siege is poorly handled by Ryman, who has Edmure put on a gallows each day but never hangs him as he doesn't want to lose his hostage.

The River Lords despise the Freys. Many of them had relatives taken as hostages during the Red Wedding, or lost relatives and men. When Ser Jaime Lannister arrives to restore order to the Riverlands, he finds Ryman spends most of his time drinking and whoring. Edwyn attends a war council in place of his father.
