Kobolds are spirits and, as such, part of a spiritual realm. However, as with other European spirits, they often dwell among the living. Although "kobold" is the general term, tales often give names to individuals and classes of kobolds. The name Chim is particularly common, and other names found in stories include Chimmeken, King Goldemar, Heinzchen, Heinze, Himschen, Heinzelmann, Hödekin, Kurd Chimgen, Walther, and Wolterken. Local names for kobolds include Allerünken, Alraune, Galgenmännlein (in southern Germany), Glucksmännchen, Heinzelmännchen (in Cologne), Hütchen, and Oaraunle. The Heinzelmännchen are a class of kobolds from Cologne, and the Klabautermann is a kobold from the beliefs of fishermen and sailors of the Baltic Sea. Many of these names are modifications of common German given names, such as Heinrich (abbreviated to Heinze), Joachim, and Walther.
