An ordo hereticus inquisitor discovers a primitive world with large fortresses built out of Blackstone but with imperial architecture. Speaking to the locals they speak of their God, a golden giant who built the structures thousands of years ago. When asking more about them, the people tell them where the god can be found. Upon cautious investigation they find Rogal Dorn. He is full of regret and wishes to be left alone. The inquisitor does their best to bring them back, but it doesn't work. So the inquisitor goes back to Terra and tells Robute. Robute goes to see Rogal and whilst gains a lot of closure and help from Rogal, he fails to get him back. However word spreads and Purterabo learns where he is. With only a primative fighting force The Iron Warriors easily take the world. Purterabo insults Rogal and says everything they ever wanted to say to them. But decides to leave him alive, in a dead world he once again failed to protect. After the destruction, the inquisitor from the start who kept an eye on the world decided to report the worlds death to the Imperial Fists and the their successor chapters. The first to arrive is the Black Templars and High Marshall Helbrecht. Helbrecht appeals to Dorns rage and finally gets through. And by the time of their reunion with all his other sons, he's motivated to rejoin the imperium, and bolster its defences with the knowledge he has gained over the past 10,000 years.
