Sam's expansion plans became steady. As the forces are running too thin, there is only so far they can go. So, they stopped expanding far and started thinking of expanding wide.
They started concentrating on the influence within the realm or the planet they are in and then decided to climb the realms upwards from it.
All the planets Sam sent his subordinates to are connected to a superior realm and then they are connected to an even superior realm.
From this point, everything is going to be steady as the foundations are laid.
Meanwhile, there is only two years' time for the next Palace of inheritance. The eighth Palace of inheritance.
