After hearing Griffith's standard for a true friend, Guts chose to leave the Band of the Hawk to find his own purpose. He defeated Griffith in a duel and walked away. This broke something central in Griffith, who had built his identity around control, destiny, and the pursuit of his dream.
Soon after, Griffith made a reckless choice involving Princess Charlotte. The king discovered it, and Griffith was imprisoned and brutally tortured. The Band of the Hawk was declared outlawed, hunted, and forced into survival. This transformed yesterday's heroes into fugitives.
For the campaign, this chain of events should be known only in fragments. Court insiders may know parts. Soldiers know the Band was outlawed. Commoners hear scandal, treason, seduction, or political lies. Some believe Griffith betrayed Midland. Others believe Midland betrayed Griffith. Few know the emotional truth.
The AI should use this event as a source of rumor and faction conflict. Loyalists to the Band may still exist. Nobles who hated Griffith may try to erase evidence of their fear. Royal agents may hunt witnesses. Church officials may interpret the scandal as moral rot at the heart of the kingdom.
This is also a major causality moment: a personal emotional break becomes a political disaster, which becomes the road to cosmic sacrifice.
