Equestria burns, its citizens enslaved, its goddesses silent.
Clinging to Celestia's teachings of mercy and forgiveness, Twilight journeys south across the Sand Sea to make peace with the enemy who devastated her homeland. But every step of the way, the brother they killed is there to haunt her. The brother whose family they butchered. The brother so filled with hatred he'd see Twilight betray everything she believes in to satisfy his need for revenge.
