Universally, an elemental is any magical entity who embodies/personifies a force of nature and therefore possess the powers of elemental cognizance, elemental detection, elemental generation, elemental manipulation, elemental self-transmutation, elemental expungement and elemental immunity; these powers are usually exclusive to the elemental's own unique element.
Within The Paracelsian concept an elemental is a mythic being described in occult and alchemical works from around the time of the European Renaissance and particularly elaborated in the 16th century works of Paracelsus. From the classical Paracelsusian perspective there are four elemental categories: gnomes, undines, sylphs, and salamanders. These correspond to the Classical elements of antiquity: earth, water, air and fire. Aether (quintessence) was not assigned an elemental. Terms employed for beings associated with alchemical elements vary by source and gloss.
