Many monarchies in history had their own council of advisors or privy council to help them with the day-to-day affairs of their kingdom. When I wrote Numen the Slayer, I did the same by incorporating a similar kind of council for the kings and emperors of Gradaia. In the case of the ruling emperor or empress, their Privy Council consisted of a representative from each kingdom in the Empire, the Lord Chancellor, and the emperor or empress themselves. This would give the Privy Council a grand total of eleven members and I drew inspiration from the Knights of the Round Table for them. I even included a scene of how the Privy Council operated in Numen the Slayer.
