The Space Paratroopers of the Order of the Dark Angels are among the most loyal servants of the Emperor God. Their loyalty is unquestionable, their faith is almost fanatical. However, the order keeps a dark secret, the history of which stretches through many millennia, going back to the time of Heresy Horus. In those terrible days, the legions of the Space Descent entered into a bloody battle with each other, almost tearing the Imperium into pieces. In an era of turmoil, many dark deeds were done, and now the task of the Dark Angels is to protect their reputation by hiding the sins of the past. When the Chaplain of the Dark Angels Borey captures and interrogates one of the Fallen, the events of the past illuminate the present and future of the order in an unexpected light for the Chaplain.
