"My name is Julius Decimus Heraclius, Guildmaster of the Scions of the Sun, Brigadier of the Covenant Army, loyal servant to the High King Emeric. Brother to a betrayed legion, son to a fallen empire. And I will have my vengeance, in this life or the next." ---Julius Decimus Heraclius (Imperial Templar)
