It was said the Sleipnir could traverse thousands of leagues in the span of a day. This hearsay prompted knights and kings alike to try and make the dreadsteed their own, but no one had ever managed to mount the gigantic beast. Which was unsurprising, given that it was rumored to have once been the trusted steed of the demon king himself.
In Norse mythology, Sleipnir (Old Norse "slippy" or "the slipper") is an eight-legged horse. Sleipnir is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, Sleipnir is Odin's steed, is the child of Loki, a shape shifter and god of mischief, and Svaðilfari, is described as the best of all horses, and is sometimes ridden to the location of Hel. The Prose Edda contains extended information regarding the circumstances of Sleipnir's birth, and details that he is grey in color.
