Elements & Elementals 
*The elements in art -- see our page on pyrography for some hot stuff. ;)
An unattended energy zone can allow unwanted or negative energies to come and go as they please. Elementals, spiritual creatures created by the energy of the individual Elements can also manifest into physical form through an unclosed circle and wreak havoc! Each of the Elements has a personality type ruler, or overseer, and also the creature associated with that individual Element. Those creatures are the elementals and they get their energy from the element that rules them.
Here is a list of elementals....
This list, or a similar one, can be found in nearly all Wicca and witchcraft books these days. Use whatever feels right.
AIR : Ruler - Paralda, a male energy that is the overseer of Sylphs, Zephyrs, and Fairies. Paralda will bring the breath of life to your circle when invoked.
FIRE : Ruler - Djin (dee-yin) , a male energy that is the overseer of Salamanders and Firedrakes. Djin will bring forth light and warmth to your circle when invoked.
WATER : Ruler - Niksa ( neek-sa), a female energy that is the overseer of Nymphs, Undines, and Mer-people. When invoked to your circle, Niksa will wash it fresh and clean.
EARTH : Ruler - Ghom , a female energy that is the overseer of Gnomes, Dwarfs, Brownies, Leprechauns. Ghom will bring the strength of the Earth to your circle when invoked.
When you invoke these creatures to a session at your altar, in addition to the God and Goddess, you need to dismiss them politely when your session is through ( close your circle). Otherwise a little Firedrake may decide to cause a candle flame to jump and ignite your altar cloth, or a a water nymph might get board and bust your water pipes! Energy left undirected will fall to chaos just as bored children will tend to get into trouble.
Just an interesting side note: In my opinion, Gremlins are Earth creatures with high key energy like a crystal. That's why they start out so sweet and cuddly -- good natured. But when they are fed after midnight, the witching hour, that good energy is grounded by the food causing them to become the opposite. They turn into ugly mischievous monsters. It's not good for your body when you eat too late. I think the gremlin is a symbol for our bodies. If we allow our energy levels to run low, as in when we don't eat or exercise properly, we turn into the monster. You've experienced someone getting grumpy when their hungry, right? When we take care of ourselves, and our energy is up, we are like the sweet, cuddly, smart creature.
