The cycle tells the story of a cursed ring that grants its owner immense power but brings destruction. It follows various characters, including gods, heroes, and mythical creatures, as they navigate their fates. The "Ring Cycle" is renowned for its complex music, innovative orchestration, and grand scale, often performed over several evenings.
