The Tuath Dé dwell in the Otherworld but interact with humans and the human world. Their traditional rivals are the Fomoire (or Fomorii), sometimes anglicized as Fomorians[3], who seem to represent the harmful or destructive powers of nature.[4][5] Each member of the Tuath Dé has been associated with a particular feature of life or nature, but many appear to have more than one association. Many also have bynames, some representing different aspects of the deity and others being regional names or epithets.[6]
