Obsidian Collars

In the Red Rising Saga, Obsidian Collars emerge in Iron Gold as the stark symbol of subjugation for the once-fierce Obsidian caste, reduced to chattel through the machinations of the Society's elite. These thin gray metal bands mark a profound degradation, stripping the iceborn warriors of their autonomy and integrating them into the underbelly of the post-Conqueror power struggles. Though their role remains nascent by book four, the collars foreshadow escalating tensions around caste oppression and rebellion in the expanding Solar Republic.
