In Norse tales, Ragnarok embodies the end of the world and signifies a cycle of destruction and rebirth. It foretells an epic battle among gods, giants, and heroes, leading to the death of many key deities such as Odin and Thor. This cataclysmic event represents the inevitability of change and the transient nature of existence, emphasizing themes of fate and restoration. Following Ragnarok, the world is said to be reborn, highlighting the continuity of life and the potential for renewal even after chaos.
