The player controls War, the first of the Four Horsemen of the Apocalypse. Along with the rest of the Horsemen, his sole duty is to be summoned to the Earth once the final battle begins. War is not aligned to either Heaven or Hell but instead serves to bring order by the rule of The Charred Council, whose purpose is to maintain the balance between the two forces. He maintains a strict code of honor and will battle any obstacle in his way.
Throughout the story, War is bound to and accompanied by The Watcher, a warden sent by the Charred Council to watch over and guide War on his journey. Because of his assigned role, he is actually skeptical and cynical towards War’s actions, much to War’s anger. War later employs the guidance of Samael, once a mighty and feared demon, now imprisoned, who himself seeks vengeance against the Destroyer, leader of the victorious forces on Earth. Many other characters become central to the overall plot, recurring at times. Among these is Uriel, leader of good after their first leader, Abaddon, was killed during a major battle; now stranded on Earth seeking vengeance against those she believes responsible. Another recurring character is Vulgrim: a demon merchant who provides gear and abilities for War in exchange for human souls. Finally there is Ulthane, or the Black Hammer, who first appears hostile towards War, but then the two quickly become friends; first after aiding War in getting into Griever's lair then making War's enchanted revolver and re-forging the Armageddon Blade for him. War is known as a power hungry warrior who will stop at nothing to gain revenge for being betrayed.
