Knife Ring

Knife Ring first surfaces in Red Rising as an enigmatic Institute relic tied to House Mars' brutal trials. Across the saga it evolves from a personal survival tool into a legendary emblem of the Rising, its razor-sharp edge cutting through Gold strongholds and symbolizing Darrow's unyielding defiance. By the later books the artifact accrues mythic weight, passed between rebels and used in decisive confrontations that reshape the solar system.
