No one has actually seen it, but a fairy interpreter asked a fairy and they described it as just a cloud of smoke and once in a while you trip over something in the floor.  The fairies purposely leave their trash in the floor because they think it is funny when people trip over them.

bee
I fly around and make a buzzing sound. I manufacture honey. I can sting and hurt humans. I like flowers.
BZZZZZZZzzzzzzzzz I wonder what the vibrations of the bee means translated into human communication. BZZZZzzzzz ("Hello fairy, what is thi splace?" I can finally understand bee! Hopefully you can understand me. This is the church of the fairies. Also, Hello. BzzzZZZzz ("Church of the fairies? How did I get here, what do I do here? I was trying to find nectar...") Yes we can understand each other! Also, the church of the fairies is covered in smoke, so it can easily confused with the foggy path to the flower meadows. BzzZzZZzzz("I feel lucky to be here fairy. Do you have many bees in the fairy world?") Well, actually, the secret is that fairies are actually the result of mimic evolution, the ancestors of we fairies were actually quite similar to carpenter bees. We evolved into a humanoid like form to avoid being hunted by early humans. also, I forgot the "be" before the "it can" in my last message.  Bzzzz("Yes, we bees provide for humans and in return our numbers are getting smaller. I do not know what more the humans want from us.") Yes, many of them ask for everything from us, and in return they give us everything but love. Pesticides have limited our population and food supply, and they don't want to take responsibility. Also, when I said  I forgot the "be" before the "it can" in my last message, I meant after the "it can".  BzzZz("It is ok fairy, you are just learning the language. I guess we will never see a time where bees, fairies and humans coexist perfectly.  ") Ah, thank you very much bee, and thank you for your onion as well. Perhaps if we can put aside our differences and all work together and respect one another, we can create a better world.
