Feastfires is the seat of House Prester in the westerlands. It is located at the southwestern tip of a peninsula in the Sunset Sea. The peninsula is west of Lannisport and south of Fair Isle. Feastfires is southwest of nearby Kayce.
Dalton Greyjoy, Lord of the Iron Islands, occupied Fair Isle during the Dance of the Dragons, so Lady Johanna Lannister gathered a small fleet of cogs and fishing boats beneath the walls of Feastfires. Ironborn longships ambushed the westermen when they sailed to retake Fair Isle, however, and Lord Prester, Lord Tarbeck, and Ser Erwin Lannister were killed.  Dalton gathered longships to Feastfires and other ports to await the fleet of Lord Alyn Velaryon, but the Red Kraken was assassinated at Faircastle in 133 AC before the Oakenfist arrived in the west.
