Story:
The nature sylphs are peaceful, friendly, and mischievous creatures. Their elf-like ears are perfect for sensing and hearing things all around them, making them very hard to be caught. Most sylphs are the size of your pinkie at the full grown size, but the queens of the elects have the ability to grow into a human size. (Like this one^) Along with their mischievous side, they love to have fun and make fun. They take the scales that fall off of merpeople's tails and sew it with other scales, until it makes a mer-tail. They like to get into the water and swish their tails around in the human oceans until a fisherman sees it in the distance. But sylphs are quick, and they cannot be easily caught. So it's a real struggle for the fishermen to to Rey to catch their 'mermaid' which makes lots of fun for Sylphs.
But even the queen Sylphs love to make mischief. They will play all day and just have fun. But they have the important responsibility non the less. The queens are plentiful, but each queen tends to a different element of the world. There are ice sylphs, water sylphs, earth sylphs, and (obviously) Air sylphs. The nature sylph is able to heal any tree, create new plate life, as well as animal life, and she is the protector of all of the forests.
