King Invern's attitude was that of a benevolent king, as he believed that despite being royalty it was important to uphold their duties as sovereigns. While he was not a war-like man, he knew the importance of vigilance and strength. Due to his eagerness to work, King Invern was frequently out on business, both in the Royal Capital and other cities.


King Invern was a man who could be compared to the kings through the history of the royal family. He has thus been hailed as stepping into the realm of heroes within its first generation.[1]

  • The king's full name is never disclosed in the Bonus Novel.


  • (To Keno Fasris Invern): “Our country is not a peaceful one. There’s no telling when these quiet, peaceful days will come to an end and a king must personally go to the battlefield. Therefore, anyone with the potential to become an exceptional magic caster should learn battle-effective spells.”
  • (To Annie Fasris Invern): “More than a girl, she is a princess, she is royalty. While there is no need to outdo everyone else, being overshadowed will be troublesome. After all, you are a better magic caster than I am.”
  • (To Keno Fasris Invern): “As the royal family of this country, we enjoy luxurious lives, and the loyalty of many people. And all that is because we have done our duty as the nation’s royalty. Therefore you must learn and absorb everything and make good use of it. It is true that our country is peaceful now. But who knows, we might be invaded some day. Therefore we need a wealthy nation and a strong army.”
  • (To Keno Fasris Invern): “There is no need to invade others. A strong army is a deterrent force. However, thoughtless intimidation will lead to conflict. It is the duty of a leader to gain information on other nations, strike a balance, and seek the growth of his country’s strength. Do you think military might is unnecessary?”
  • (To Keno Fasris Invern): “You do not need to do everything by yourself. Gather the people you trust and borrow their strength. I am not unique in strength among the many kings of history, but even I have people that I trust.”
  • (To Keno Fasris Invern): “Therefore, gathering the strong and seeking strength that lies in a different direction from your own might be the right way. But what does that mean? Perhaps learning spells that make everyone happy might be one way to do it. However, this is a suggestion from your father. You cannot neglect your own strength. People feel at ease under the protection of the strong. Being a member of the royal family, is a form of strength that draws the masses to you. Naturally, such strength implies possessing charm, wealth and authority. But if you take it to an extreme, then the king’s personal power is the most easily understood strength of all -- and it can better ensure your safety. After all, charm, wealth and authority can sometimes fail to ensure everyone’s safety.”
