To learn more about Druj, the team travels to the Shrine World of Eleusis to speak to the Deathwatch Kill-Marine Septimus. When they arrive, the various leaders of the Ecclesiarchy here immediately try to draw them into their internal struggles, which the team tries very hard to resist. During their time on Eleusis, the team learns of a series of brutal murders, apparently targeting knowledgable members of the Adepta Sororitas. They ultimately decide to use Canoness Galatia of the Whispering Cloister as bait for what turns out to be a Tyranid Lictor, which they kill thanks to the help of a squad of Flesh Tearers on world to train the local Frateris Militia.
Septimus provides the team with all of his information about Druj, who appears to have vanished some time ago.
