In Norse mythology, Garm is a huge dog which guards Hel, the land of the dead, alongside of Hræsvelgr and living in a cave called Gnipahellir. Garm was the greatest of all dogs (excluding the Fenris Wolf). During Ragnarök, Garm and Týr will kill each other. In Völuspá, the line Geyr Garmr mjök / fyr Gnipahelli (Garm howls loud / before the Gnipa-cave) is repeated three times. After the first occurrence, the Fimbulwinter is related; the second occurrence is succeeded by the invasion of giants in the world of gods; after the last occurrence, the rise of a new and better world is described.
