After Minos' conversation with Isabella, he took some time off from his recent pursuit of the previous quadrupedal frontier, going with Abby to where he normally stayed in this palace.
While he was resting, the supreme elder learned about Minos' return and this emperor's most recent exploits.
As such, he was furious about Minos' actions against the powers of this state without first consulting him.
But the Gray Cloud Sect's elders prevented him from seeing Minos, leaving him to go to Isabella to complain about how lenient she was towards that individual.
Minos deserved the right to speak and could even decide some things for the empire without asking for permission. The supreme elder saw it this way since this state was only still ruled by the Edwardstone family because of such a person. But this did not give him the right to do anything he wanted.
