In Norse legends, Ragnarok signifies the apocalyptic battle that results in the death of many gods, including Odin and Thor, and the destruction of the world. Following this event, the world is prophesied to rise anew, symbolizing rebirth and renewal. Ragnarok represents the inevitable cycle of destruction and regeneration, deeply rooted in Norse cosmology. It illustrates themes of fate, courage, and the perpetual struggle between good and evil in the realm of the gods.
