The magical trio had originally been a quartet. Two women and two men, who had brown, blonde, ginger and black hair; they were inseparable. Unfortunately for them, they had been born in a time when Voldemort and his followers were at large. Families had been murdered, children used as weapons and spouses torn apart by the need to survive, with or without each other. It was a dark and horrible time for all.
One by one, most of the quartet were taken from this life. It started with the brown-hair woman and the ginger-hair man. Their little family were never given a chance as Death Eaters busted through their house in the middle of the night and ruthlessly snuffed out the lives inside. Soundless and swift were the murders. No one knew for days, for fear of leaving home had ensured that it was normal to not hear from friends and family for days.

Their memories stayed in her mind and after awhile, they started niggling at her, begging to be remembered better.
The blonde woman decided to do something about it. Visiting her local cafe, she sat down and started writing about a magical trio who saved the world. Changing their ages to a time of their lives when the world truly was their oyster and all things were possible, she envisioned for them a great adventure. One where, she thought tearfully, they would live through a great childhood, survive and live happily ever after. As for that black-hair man, he would get the best ending she could write. The memories of her friends would never be forgotten, and the world would know it. And so, the blonde woman started writing...
