There are no such things as "Wiccan Powers".
Wicca is a religion with specific beliefs and practices, not some sort of special powers such as one sees in the TV show "Charmed" (The show has absolutely nothing to do with real Wicca at all!)
Actually, the idea that you have an Element isn't correct. It's something that Hollywood dreamed up in the movie, The Craft, and someone people latched onto it and it won't go away.
We are not one Element, we are composed of all of the Elements. What we truly want to do is learn to work with all of them in balance. It is true that you may find that one or two of the Elements are initially easier to work with. That isn't because they are "your Elements" but because you need to spend more time and effort learning to work with the others that are more difficult for you.
Nor is it true that "your Element" is the Element of the Sign of the Zodiac in which you were born. Anyone who does astrology can tell you that your birth sign is only a portion of what influences your life. Which Houses the other planets fall in also has great influence. Take myself for instance, I was born in Taurus, which is an Earth sign. But I also have planets that fall under Water, Air, and a lot in Fire. So again...I am NOT one Element only.
Which Elements you work with also depends in part on which forms of magic you practice. The classic Elements in Western magic are Earth, Air, Wind, and Fire. Some also add the Element of Spirit to that. In Chinese astrology and magic the Elements are Metal, Water, Wood, Fire and Earth. That's why it is important to understand what you want to work with and in which system you are working because it changes the perceptions regarding the Elements.
I would think that someone who calls themselves " masterwiccan " and claims to come from a long line of Wiccans would be aware of this. But then you also claim to come from a line of Wiccans going back to the Burning Times. You do realize do you not that there were no Wiccans around during the so-called Burning Times ? Wicca is a thoroughly modern religion put together in the 1930's and 1940's in England by Gerald Gardner. Perhaps you are confusing Wicca with Traditional Witchcraft. The two are quite different things.
