Toru, Varg, and Duril embark on a new adventure, this time accompanied by their newfound friend, the bearshifter Claw. Leaving Shroudharbor behind, they head toward an even bigger challenge than in their previous adventures. In front of them lies the Great Barren, home to the orcs and their fearsome tribe called Zukh Kalegh, a name given to the bloody desert by their rightful ownership of the place.
It is Duril's turn to hear a call, the one of blood, and one night, when it grows too strong for him to ignore, he follows the scent in the wind, unwittingly forgetting his companions.
A tale of brotherhood, roots, and unbreakable bonds rises from this call of blood. Will the heroes prevail once more when the evil grasps the desert in its dark fist?
