The Hound Garmr Howling and Breaking Free from Gnipahellir
Garmr, the blood-stained hound of Hel, guards the mouth of the Gnipahellir cave at the threshold of the underworld. According to prophecy, his thunderous howling signals the arrival of Ragnarök, the twilight of the gods. When the world begins to end, Garmr breaks his iron chains, escapes his subterranean vigil, and joins the final battle where he and the god Týr ultimately slay one another.
