Avatar: The White Demon's Revenge ATWDR

In a world marked by the invasion and massacre of his village, Thorian, the sole surviving child, harbors a fierce resentment towards the invaders from the Fire Nation. From his adolescence into adulthood, his quest for revenge leads him down a dark path of learning centered on violence. Eventually, he is compelled to gather the survivors to end the war, facing a crucial decision: resign himself to the endless conflict or seek a way out that will halt the bloodshed.
