Rozen commands the Order of the Seven Lances, Glenn's personal military force. He initially works alongside Koinzell, but things get complicated once he learns the truth about who Koinzell really is.
The turning point comes when Rozen overhears a shocking revelation: Koinzell is actually Asceriit, and the real "Lances of Betrayal" weren't mythical weapons—they were the Seven Heroes themselves. This discovery puts Rozen in an impossible position. He understands Koinzell's desire for vengeance, but he can't bring himself to support it. His reasoning is practical: even if the Seven Heroes were genuine traitors, the entire empire's foundation rests on their legacy. Tearing that down would destabilize everything.
What makes Rozen's situation worse is that he knows the real history. He's heard the actual story behind the Seven Heroes and the Lances of Betrayal, which means he can't just dismiss Koinzell's grievances as baseless. He's caught between acknowledging a terrible truth and protecting an empire that depends on a lie—or at least a carefully maintained story. It's a conflict that clearly weighs on him.
