Kelpie was a magnificent black mare originally owned by a man named Hotsporn. After his death, the mare became Ciri's mount. Although Hotsporn had never named the mare declaring that it was silly to name animals, Ciri named her Kelpie. The name came from Ciri's first sighting of the mare and Hotsporn crossing a river. The girl was immediately smitten with the mare. Ciri's choice of name for the horse greatly amused Vysogota.
Kelpie could be summoned by rubbing a magical bracelet. This was particularly helpful when Hotsporn died as the mare had been set away to lead the brigands astray.
