to save some time(and my energy) make a search on the pentagram. I beleive that we all belong to an element of the petagram. being water facilitates healing and pretection spells, water being the greatest symbol of the two. I, for instance, am water. Now you might ask yourself "am I water too?" and thats a tough question. understand water and the answer to that question is easy.
water: takes its time but gets there eventualy, peaceful and relaxing but to be feared when angered, water keeps life alive. It adapts to its environement and it can take many forms. Water understands its situation before acting.
My goal here is to rally all of the water individuals to create a coven of water wizards.
does that answer to your question or did you want to know exactly HOW water magic works?
