Ken and company find that with the introduction of the Threadspawn, the whole dungeon becomes far less friendly. Even the populace on Earth is spooked.
Which is why the UG and Haylon sends Ken and a few others on the press tour. Though, even that can't keep Ken from the action. The Threadspawn invade Earth meanwhile Ken is recruited fully into the demon hierarchy.
Now he has to balance loyalties to the UG and the Hierachry while the Threadspawn threat grows ever closer.
