The King of Midland basically made Griffith what he is today. As the ruler of Midland and father to Princess Charlotte, he's the one who saw potential in Griffith early on and ran with it.
The turning point came when the King's army was getting crushed in battle until Griffith and the Band of the Hawk turned things around. Impressed by both Griffith's power and intellect, the King became his biggest supporter. Promotions came fast—nobility, the title of Guardian of Midland, constant rewards for victories. He couldn't seem to promote Griffith quickly enough.
But that relationship completely fell apart when Griffith, desperate after losing everything that mattered to him, made a move on the Princess. It's the moment the King's goodwill evaporates, and their dynamic shifts from patron and protégé to something far more hostile.
