Tanith Low is a master swords-woman who is first introduced while battling a troll on Westminster Bridge in the first book. Tanith does not work for the Elders (who are the leaders of the magical communities which are mainly divided by country), because she has a natural distrust of authority. Instead she merely, as Springheeled Jack says in 'Playing With Fire', "deals out what she calls justice". She is English and originally lived in London. Tanith Low's job is to apprehend or otherwise kill criminals and evil creatures who threaten national security.
