- ―Tyrion Lannister
Gunthor is a member of the Stone Crows, one of the hill tribes of the Mountains of the Moon recruited by Tyrion Lannister to fight for him in the initial stages of the War of the Five Kings in exchange for gold, weaponry and armor the hill tribes could employ against House Arryn.
Tyrion reports to his father and his uncle that Ulf, of the Moon Brothers, is demanding blood money from Shagga, of the Stone Crows. Shagga, Gunthor, and a third Stone Crow had killed a Moon Brother after the latter stabbed a Stone Crow over a sausage.
In the booksEdit
In the A Song of Ice and Fire novels, Gunthor son of Gurn, along with Shagga son of Dolf, and other clansmen, meet Tyrion and Bronn in the Mountains of the Moon. In the novel, Gunthor is the first to introduce himself to Tyrion by saying Shagga's TV-series line: "When you meet your gods, say it was Gunthor son of Gurn of the Stone Crows who sent you to them." Later, instead of departing with Tyrion to the Lannister camp, Gunthor stays behind at the Mountains to rally the members of the hill tribes.
