rahg na rok', literally judgment of the Gods, but usually taken as meaning twilight of the gods, a time which the northern people believed must come, when the great gods should come into mortal conflict with the powers of evil and should be overthrown; when the dwellings of the gods should be destroyed and all earth should be desolated. It was believed, however, that although the most of the great gods were to be killed by the powers of evil which would be let loose when Ragnarok came, a new generation of gods would arise who were to rule over a new and purer heaven and earth.
