Sow's Horn's location is roughly the same. It is a small settlement that serves as an seat to House Hogg, a family of landed knights. It consists of a small village dominated by a towerhouse with tick walls.

House Hogg is sworn to House Hayford, which controls the surrounding lands. Due to its proximity to the Riverlands and the frontline between the factions of the War of the Five Kings, Sow's Horn has seen its share of raiders and foragers. It was raided by the brigade of Amory Lorch, sworn to House Lannister, despite its allegiance to House Baratheon of King's Landing.
