It seems psychic abilities are intimately tied to crystals. Its everywhere. They are used with mysticism, psychic healing, Wicca, and so on. Even in fiction and science fiction books, they are tied together.
I'm guilty of it.
In the story I'm writing there are people, and in some cases, entire races of people who have psychic abilities.
Abilities are tied to the 5 elements, planet/earth, wind, fire, water, spirit and that correspondence determines their abilities.
A couple of examples:
While the 'how it all works' is the same, they aren't viewed as the same. (one culture considers it magic, another has the right of it, etc)
Some races have developed their psychic abilities alongside their technology and have even combined the two so it is part science/technology, part psychic abilities. (I still have no idea what to call the mix of tech and psychic abilities) One race has developed this to the point that crystals are used for a wide array of things, storage of energy, memories, histories, an entire library of information crystals. They can even use the crystals (providing they have the right correspondence) to link to computers and ships)
They have found certain crystals are able to amplify their abilities (sort of the way different types of crystals are used in Chakra healing and balancing).
After recently seeing several instances of crystal and magic/mystic/psychic connections, I'm rethinking my use of them. Is the concept still interesting or is it ho-hum, another psychic crystal connection?
