An Elemental is a being from the alchemical works
of Paracelsus in the 16th century. There are four
elemental categories: gnomes, undines, sylphs, and salamanders.
These correspond to the Classical elements of antiquity: earth (solid), water (liquid), wind (gas), and fire (plasma). Aether (quintessence) was not assigned an elemental.
Terms employed for beings associated with alchemical elements vary by source and gloss.
Gnome, spirit of earth.
Undine, spirit of water.
Sylph, spirit of wind-air.
Salamander, spirit of fire.
