This Gaelic word translates to 'water horse'. A goblin of highland legend, the Ech-uisque took the form of a Kelpie to lure souls from their masters to the devil. The Kelpie would pose as a beautiful stead casually grazing until a tired passing traveller would discover him and decide to use him as he continued his journey. As soon as the victim mounted the steed, the Ech-uisque would laugh evilly and plunge into a nearby pool. The Kelpie was said to receive the unfortunate traveller's body for his trouble, and the soul was taken by the devil.
