With Kalis' betrayal revealed, Erich no longer had to dedicate his time to searching for the traitor. For the time being, there was nothing he could do about it. Evidently the threats he had made to the Ghimderi Trade Union had resulted in them covertly backing the Emrys government, because while Emrys preached the whole normal spiel about ending the Ghimderi Trade Union and their influence over the Galactic Economy, both Emrys, and the Ghimderi knew he had no such plan.
To put it simply, Erich despised the Ghimderi, perhaps more so than any other Supreme Leader of the Germanic Star-Empire in history. That is, assuming he emerged victorious and seized their throne. He had seen their attempt to destroy his homeland first hand, and understood how far their reach was. Thus, he had no qualms about calling a spade a spade, so to speak.
