Both Collete and Barnabas looked at their older brother with shock, maybe, a tiny bit of terror. The difference between each Minor Realm of Sovereign Realm is well known, especially to them.
After all, they have trained and spar with their older brother before, when they entered the Sovereign Realm, and he was still a Single Palace Sovereign.
When he entered the Double Palace Realm, they spar with him once, and then said to any future suggestion with "never again."
However, the look he was giving them tell them they could not refuse this time.
"If His Majesty wanted to spar with the Grand Duke and Lady Collete, maybe the Marshal and I can join in as well." The Captain said. The two named Sovereigns did not say anything but inside, they are overjoyed. Even if they were beaten by him, at least they did not have to suffer all alone.
