In Norse legend, Ragnarok signifies the apocalyptic destruction of the cosmos and the death of many gods, including Odin and Thor. It represents not only the end of an era but also a rebirth and renewal of the world. The myth encapsulates themes of fate, heroism, and the inevitability of change, highlighting that destruction often paves the way for new beginnings. Thus, Ragnarok serves as a powerful reflection on the balance between chaos and order, essential motifs within Norse cosmology.
