Faeries are very old beings. Many of their cultures range from Celtic to the Sidhe, people of the mounds.
Faeries are great spiritual creatures of the natural world. They have been known to the Nordic, they were the alfar or elves. A vision quest is a great journey into a quest to the unknown reaching to the other worlds in order to learn about merely the Subconscious Realm of their World.
Mystical realm which mirrors the astral planes and other portal holes in which they are able to come through both worlds is a way of protecting their children whether they are faerie, in the form of an animal (shape shifting), or anything that is one with this planet, that they have come to love.
The Faeries are acknowledged in every aspect of life. Along with this comes a respect for all any shape - size of life ... from a tiny lady bug, to the rare spirit bear, to a giant redwood tree or a spring mist.
