After defeating Genka and the strange beast, the Explorers are back aboard the Hotspur, along with all the psykers from the Citadel as well as Ullina. The few guards left are aboard the Gibbs and the rest of the Polnia PDF.

Cassandra was called upon to mind probe him, and plunder his mind she did. Now, in orbit around the Hollow World, the Explorers recover from their wounds and determine what to do next: Head to Polnia Prime? Assist Magos Terber in liberating Gears? Or take on the void wasps and whatever else may lurk in Installation 17?
