Folklore is ingrained in cultures around the world and is one of the most common inspirations for fantasy fiction around. For as long humans have been curious and looking for explanations, folklore has been there to fill in the gaps. Human minds created thousands of fantastical creatures and unique worlds, separate from our own in an effort to explain the workings of the world. A family with an unruly child might be nurturing a changeling, while the striking of lightning might signal the fury of a grand spirit. When items went missing in a house, there were stolen by gremlins or other creatures. These beliefs used to be common knowledge, known to be true around the world. But there comes a certain point in every culture when people stop believing, when the explanations for phenomena are found to be mundane. The belief may be gone, but the influence of these stories lingers.
