|Title||Lady of Raventree Hall|
|Died||In Century of Blood, Riverlands|
|Issue||At least four sons|
|Book||The World of Ice & Fire (mentioned)|
Agnes led the Blackwoods when King Harwyn Hoare of the Iron Islands invaded the northern riverlands. After Samwell Rivers' small force was destroyed by Harwyn on the Tumblestone, Lord Tommen Tully joined his strength to that of Agnes at Raventree Hall. When she marched on Harwyn's ironborn, however, Agnes was attacked from behind by her neighboring rival, Lord Lothar Bracken. Lothar delivered Agnes and two of her sons to Harwyn, who strangled the boys himself. Harwyn offered to make Agnes a salt wife, as he was impressed with her demeanor, but she said she would rather die; he stabbed her after her rejection. The defeat of the Blackwoods ended the rivermen's resistance to Harwyn, but the Storm King Arrec Durrandon then marched on the ironborn.
I would sooner have your sword inside me than your cock.—Agnes to Harwyn Hoare
