The Harpell family was an eccentric clan of wizards who, for the most part, lived in the Ivy Mansion in Longsaddle in the Savage Frontier of northwest Faerûn. Despite their eccentricity and their strange experiments, they were well known for collectively having a vast knowledge of the history and geography of the North.
During the Keepers' raid of Longsaddle, many of the Harpell wizards died protecting the town from Lennithon.
