Charles never thought that his conquest of Modova, and his subsequent occupation, would actually be recognized by the Lionheart Dynasty.
And it was the highest level of recognition!
The Great Berenhill, King Baldwin Asa, personally delivered the state letter!
There was no more formal ceremony than this.
Charles also slightly understood that a large reason why the Lionheart Dynasty was willing to recognize this was their preference for having one more friendly neighboring country on their border since the previous Duke of Modova was likely not very amiable towards the Lionheart Dynasty.
For the Lionheart Dynasty, Modova was a place of no value for rule, considering that Arsen Lupin had to lead the life of a bandit in Modova and it was tough going, requiring Princess Akso to sponsor him twice a year.
If even the life of a bandit was so tough, how could the lives of the common residents of Modova be? It was, frankly, not hard to imagine.
