Prior to the Battle of the Blackwater, Tyrion recognizes that the Moon brothers and the other hill tribes, while ferocious, are undisciplined and inexperienced at siege-warfare, so he sends them south across the river to the Kingswood to harass the scouts and raid the baggage train of Stannis's army as they approached the city. Tyrion is careful to keep them away from the Stone Crows. In A Clash of Kings, Crawn and his Moon Brothers serve as guards for Tyrion in King's Landing. Ulf is succeeded by Crawn son of Calor as the clan chief. Ulf and at least a dozen of his tribe are killed in the battle. Ulf and more of the Moon Brothers are among the clansmen who follow Tyrion to the Lannister camp, and subsequently participate the Battle of the Green Fork. The Moon Brothers are perhaps the clansmen who attack Catelyn and her escorts on their way to the Vale. They have strong bonds with the Black Ears, but are enemies of the Stone Crows. In the A Song of Ice and Fire novels, the background of the Moon Brothers is the same. įollowing the Battle of the Blackwater, Varys informs Tyrion that Tywin has paid the hill tribes quite handsomely, and they have gone home. The Moon Brothers escort Tyrion to King's Landing, where he takes his place as the acting Hand of the King on behalf of Tywin. They take part in the Battle of the Green Fork. While heading to the battlefield alongside the Lannisters troops, the Moon Brothers bicker with the Stone Crows. The Moon Brothers are among the hill tribes that Tyrion recruits, in return for money and weapons to take over the Vale for themselves.
