These attacks influenced which worlds were originally chosen (or not chosen, as the case often turned out to be). As the Rock was in an adjoining sector, it was not long before the Mauler was secured in its deep dungeons. Upon closer inspection, it was obvious that the stronghold was constructed not as tribute, but in mockery –- a Tower of Fallen Angels.

Persuaded by the harsh methods of the Interrogator-Chaplains and the relentless mind-probes of the Librarians, the Mauler eventually revealed that he had been known by another, older name.Others, however, would be appalled to realise whom they have aided, and have been duped by an erstwhile ally who is not all he seems.

The Dark Angels' impetus was all but spent by the time Alloken appeared before the chainaxe-wielding Ork Warboss. The Lord Cypher advised the masters on all matters of protocol and officiated at many important ceremonies.Across the galaxy, the legend of Cypher –- the mysterious loner who fights for freedom –- has been known by many names. Reports of the Dark Angels' actions on Brigia had already reached Terra and questions began to filter back to the Rock. Yet what can be learned from such a paradox of information, other than the fact that he is apparently as likely to work with as against the forces of the Imperium? The chase for Cypher stretched from years into decades, until it came to a grinding halt when the trail led to the densely populated world of Brigia. The great tower bore the unmistakable icons of the Dark Angels –- the hooded and winged figure bearing a sword.

This is a convenience which the Dark Angels have taken advantage of, for by claiming their records were damaged in a plasma reactor overload as they outfitted the Rock, they could veil a fraction of their past.and there is a suggestion that he cultivated minute events decades ago to facilitate some of the events in this book, such as the power in the prison complex failing due to a faulty component made on mars a long time ago. However, this is unlikely, as this Lord Cypher was an ally of the Watchers in the Dark and an enemy of Chaos, whereas the Knights of Lupus sought to preserve the Chaos-tainted Great Beasts of Caliban and books from their library contributed to Luther's fall to Chaos. To this day, there are even some of the Fallen that have not yet been released back into the galaxy.
