Some Wiccan traditions whose practices utilize ideas from Ceremonial Magic acknowledge elemental beings as "Guardians of the Watchtowers" of the four corners of the ritual Circle. These elementals are creatures that personify the qualities of Air, Fire, Water and Earth. The element of Air, in the east, is associated with the elemental spirits known as Sylphs. Fire, in the south, is associated with Salamanders; Water, in the west, with Undines; and Earth, in the north, with Gnomes.
Undines are also known as nereids, oceanides, nymphs, and mermaids. They are usually female.
