From their website:
Fantasy Flight Games is pleased to announce the upcoming release of Tribes of the Vale, an ally force expansion set for Battles of Westeros. Born in the cruel climate of the Mountains of the Moon, the clansmen of the Stone Crows, Black Ears, and Burned Men are of a violent breed. Uncivilized, uncouth, and unrefined, these men and women live to kill, and they do it well.
The Tribes of the Vale expansion adds three new ally commanders to diversify your Battles of Westeros experience. Shagga, Son of Dolf is a ruthless barbarian of the Stone Crows, capable of wielding two massive battle axes better than some men handle one. Timett, Son of Timett earned his place as the Red Hand of the Burned Men by taking out his own eye. A fearless expert swordsmen, Timett rarely fails to kill anything he sets out to. Finally, Chella, Daughter of Cheyk is a vicious woman, decorating herself with the ears of her enemies.
