Its said in Irish mythology that the Aos Sidhe have the power to conjure a mist, the ceo draiochta, which hides them from mortal sight and allows them to pass through the human world as they will without human interference. They teach this magic to the Tuatha De Danann when those Powers go into the sidhe so that they too can pass unseen when they will. 

For someone studying fairies or seeking a path that is based in fairy belief this magical mist may or may not be a factor in physically seeing fairies but on a figurative level it certainly seems to be an issue in finding out anything about them. Information is hard to find and often distorted, like the image of a landscape through a heavy mist, and terms are fluid and hard to define. The more you walk into the mist the more lost you feel. The more you learn the more questions you have. 

This being so, then what are we to do to learn more about these beings? I think ultimately there are two steps that must be taken: we must expand our minds to understand that the answers are often contradictory without being a contradiction; and we must stop trying to see the horizon through the mist and focus on familiarity with our immediate surroundings. And perhaps a third step - we must keep moving forward. 

This is not a subject that is easily understood or which offers easy answers, but it is one that is valuable and worth pursuing. The mist is all around us; we must keep moving through it.
