The sixth day after their arrival to the base, Han Sen summoned everyone to a plaza.
He had been busy over the past few days, writing out the document of ground rules he dubbed the Han Family Discipline. If there was no rule of law, the place would not be considered complete. It'd be impossible to gather people of different cultures and races, and expect them to live together in harmony, if there weren't any rules established.
Han Sen had brutally killed a Baron, and the other Barons and Viscounts had behaved awkwardly, following the deed. They wouldn't disobey one of Han Sen's orders, but they also wouldn't fight and prove their worth to him as hard as they would have otherwise.
So, now, Han Sen summoned everyone together. On the stage, he said, "I don't care where you came from. I don't care who you are. From now on, you are a servant of the Han family. Everyone here is equal, and there are no exceptions to that."
