Kelli was born Kelloine Frostbone, a proud mountain dwarf of Mirabar near the Spine of the World. Like most dwarves she is trained for war, using all sorts of weapons and armor; currently wearing a hide armor with a lining of black fur and using a hefty old warhammer. Her skills are not only limited to the battlefield, she has been trained by the Shadow District to apprehend criminals. Later, she was recruited by her uncles Molon and Bruldenthar to the Harpers. She is fond of history, music and poetry and dabbles in magic.

Standing only 4 feet 6 inches and weighing in at about 120 pounds, Kelli is not a very big person, but she easily fills a room with her presence; be it through friendly laughter, song and conversation - or righteous fury when friends, family or innocent people are threatened. She has an attractive face, although scarred from a recent fight, with white hair and light-colored eyes. When not engaged in talk, she prefers to read books with old dwarf sagas or play a musical instrument.
