Hati

In Norse mythology, Hati Hróðvitnisson (first name meaning "He Who Hates", or "Enemy"^[1]) is a warg; a wolf that, according to Snorri Sturluson's Prose Edda, chases Máni, the moon, across the night sky, just as the wolf Sköll chases Sól, the sun, during the day, until the time of Ragnarök, when they will swallow these heavenly bodies.
