Everyaone left the Palace the way they came, it was clear that any small gathering, even if it were just two generals or lord, could be counted as rebel. The princess was using an iron fist.
No matter how displeased many people were they had to obey, after all as the few, if they dare to disobey the royal family, then the many would do same. The balance that kept the noble and commoners together, if broken, the consequences would be too dare.
Those who were tempted to support Robin did not even dare to turn to great the next person in their side. It was obvious that the princess has been paying attention to General Daiz moments. Even those who did not agree felt that it was better to be safe.
Noble who wanted to rule with the iron fist would rather kill by mistake than leave a threat behind. The princess had not done anything. Even if she had, this was a time to mourn the king, who would dare bring up that topic. The dead king most be paid his full respect.
