Enter the Chaos Space Marine

At the climax of Chapter 1, the player party has fought their way back to the starport on Rykad Minoris... to be confronted with a Chaos Space Marine as the chapter's final boss: a heretic Astartes of the XVIIth Legion "Word Bearers" who smashes his way through the Rogue Trader's shuttle. He reveals he was the true mastermind behind the Final Dawn heresy and the puppeteer of the seemingly slain cult leader Aurora. (Video by troper StarSword.)
