After securing the allegiance of the Bloodied Hand Clan, Erich realized he was back to square one, regarding just where the Sages might be, and because of this, he decided to take some time off from his pursuit and spend it with his loved ones.
There was the matter of Tia needing to outfit his Orc Horde with new equipment, ships, etc. Not to mention Tia and Mirage would have to work together to find their next target. Because of this, Erich returned to Germanic Space, while the rest of the Orcs began moving their fleet towards Tia's industrial world.
The moment Erich stepped foot at his doorstep, and knocked on his mansion's door it was immediately opened, revealing Erika and Ayumi who welcomed their husband home with loving smiles. Of course, that lasted for about three whole seconds, until they realized there were more women surrounding the man than normal.
