Episode 67 - The Knights Destiny 4 'The Imperial Decree 3'
Following the Emperor's order to rise up, everyone rose up in union and faced the Imperial family sitting above, however not directly looking at them. In their hearts, they were sure that something was to slap their faces today, and that's why they were nervous. Everyone had an inkling that the Emperor would bestow a big decree and that was because the Imperial guards led everyone to gather at the throne room and not the audience room.
Another thing that caught them by surprise is that the decree to enter the Imperial palace today stated that they must bring their spouses and children. This was especially weird because women are not allowed to interfere in matters regarding the court, which would normally apply to today as well when a big decree will be passed.
