The Khun people's annual pilgrimage to the Sacred Mountain turns tragic when a ruthless eastern tribe known as the Krull launches a devastating ambush, scattering the survivors and forcing the entire civilization into exile across the frozen wastelands of the North. Generations pass in hardship and preparation as the Khun elders condition their youth in warfare, grooming them for an eventual reckoning. From this new generation emerges Atrog, a warrior whose aptitude and resolve mark him as the chosen instrument of his people's vengeance. Now tasked with both reclaiming the sacred relics stolen during that fateful raid and destroying the Krull threat once and for all, Atrog must draw upon years of training to restore honor to his displaced nation.
