These stories serve as a direct sequel to the Barrowman's previous Torchwood novel, Exodus Code as well as make reference to Big Finish Productions ongoing Torchwood audio series Toshiko manages to stop the Hub halfway to its destination by using the Rift Manipulator.
Jack tells Ianto and Gwen that the Harrowkind's distraction was so that a giant Rift storm could be generated to steal the Hub.
Owen and Gwen are investigating Rift activity at Cardiff Castle when they are suddenly trapped in a large vortex full of medieval knights.
Meanwhile, Owen is attacked by one of the knights and when Gwen tries to shoot it, the illusion shatters and they fall onto a giant teddy bear.
Sitting next to the bear, watching a hologram of knights fighting, is a Zansi Baby; a huge humanoid infant.
The Baby's presence within the castle is put down to unstable Rift energy within The Sanctified's Empire – something they blame Torchwood for.
