Definition: The term 'raiderep' comes from Norse mythology, where it refers to a powerful being known as Ragnarok, also known as the end of the world. In the Norse pantheon, this being represents the ultimate battle between good and evil, culminating in RagnarΓΆk or the final battle described in the Book of Edda, which tells the story of the gods' conflict with humans and ultimately their defeat at Ragnarok.
