If you take a poll about what a “fairy” is, you'll get as many answers as there are those taking the poll. But the basic answer is yes. These are directly related to workers of the earth. The “devas” of the gardens were seen as fairies, and so were other Earth-related helpers. They are also part of sea lore. So in the context of “Tinkerbelle,” the answer is no. In the context of interdimensional creatures that are the helpers of Gaia, yes.
