First Born Fairy

Fairies were never born but created by the first laugh of an infant.
Fairies are tiny creatures that love the environment and love the world the way it is. But as time passed and new gadgets were created and the world was becoming a place of smoke and fog and new gases the fairies didn't know how to survive.
The Fairies were in little numbers and the only hope they had was the hope that a fairy would come along and save the day.
This fairy has been passed on by generations. This fairy would not be created by an infant's laugh but actually be born as a human and have all the powers to save the world and restore it o it's glory.
The fairies waited patiently for this fairy to come but after hundreds of years the fairies gave up hope and decided not to help the humans anymore so they retreated back to the Fairy World and never came back and that's when the world turned bad. Wars. Blood Shed. And Deaths all around.
It was something that could be prevented but it wasn't until this fairy was born.
