In Hollow Knight, the Traitor Lord is the exiled leader of the Mantis tribe, found in Queen's Gardens after turning against his fellow Mantis Lords and embracing infection. His boss fight is remembered for its mournful tone, which fits a character who chose betrayal over loyalty. Short clips of that sad violin moment have circulated on soundboards and in edits, where creators reuse it far beyond the game itself. It endures because betrayal is a universal joke setup, and the music instantly signals exaggerated grief without needing any dialogue or explanation.
