Hoshi is the mare given to Keladry of Mindelan by her knight-master Raoul of Goldenlake and Malorie's Peak, when Kel became his squire. The mare serves as Kel's remount and her horse for fast riding, while Peachblossom, the horse Kel has been riding since she became a page, is her warhorse for use in fighting.
Hoshi is a brown mare with feathery white socks and a white star on her forehead. Her mane and tail are black. It was Kel who named the mare "Hoshi", which means "star" in Yamani and refers to the white star on her forehead.
