You are an Acolyte in the service of the Emperors' Inquisition. You stand in the front line of a great and secret war where your duty is to hunt out the foul stench of heresy, the vile alien, and the twisted influence of Chaos. You will tread where others fear, venturing to distant planets, ancient space hulks, and the unsavory depths of the under-hive. You will never know fame nor reward, yet if you stand resolute your deeds will be whispered to the God-Emperor of Mankind and your name will be revered for millennia! The Dark Heresy core rulebook contains everything you need to start your roleplaying adventure in the Warhammer 40,000 universe.
