WHAT IS A FAIRY?
Fairies are small creatures that could be easily squished by a human but luckily their magical powers protect them. Fairies are about 1-2cm tall so we can't see them in the grass. They have two wings and are very vulnerable.
Traprain Law is a popular meeting place of theirs. They have their meetings in the dead of night so not to be disturbed.
They supposedly live on mushrooms, bushes and trees.
