Prologue

" Haha...No way." We all laughed heartily together at Erza's S-class adventures when my heart started beating wildly. I clutched to it tightly and stood up while staggering on my steps.

" Lucy?" My teammates who saw my weird behavior, asked. " Are you alright?"

I gave them the best smile I could muster for the moment and nodded.

'No...Not now...'

I clutched the part near my heart tightly, almost as if I want to rip it off. These are my usual attacks that started ever since I was a kid. I don't why but everytime it acts like that, it seemed as if it wants me to go somewhere. The pain I feel disappears when I follow my heart to wherever it is taking me.

" Lucy?" They asked again. Not convinced by the smile I gave them.

' No...Faster, Lucy. Get away from here...Faster.' I willed myself but my human body can only take me as far as the guild doors before finally collapsing towards the cold, hard ground.

Darkness surrounded my field of vision. Nothing but pitch-black darkness,but after a few moments, the part where my heart is supposed to be- glowed. Giving light to wherever I was. It was in my only oh-so-familiar Heartfilia massive garden that no one but I knows where.

There, appeared a 7-year-old me. She was happily scouting the town, after all it was the first time she was ever allowed to leave the mansion. She remembered all the townspeople bright and warm smiles. It maybe an unfamous, hidden town but the people living there are very familiar and homey kind of people. She was smiling back to everyone when a deep "roar" was heard.

Everyone in the town paled at the sound and hid in their houses. But little Lucy was too naive for the outside world, she didn't know what's happening.

'Is their curfew alarm a roar? And is it usual for ordinary people to go like that?' Lucy wondered. Ignoring the other people's weird behavior, she continued on scouting the now, eerily silent town.

She wondered why people did that and after staying for a while, she finally found out the reason. It was because the roar was made by a large, black dragon. She stared in awe at the great rumored dragon as she took cover under the trees when a sudden loud cry was heard. It came from a child who was left by his parents from the ruckus earlier.

The loud cry of his had attracted the dragon. It had his eyes set on the child, and plans to kill it easily by stabbing its claws through his heart. Acnologia did just that. Only... the child he was planning to kill, was alive and in his place, was a slightly older little blonde girl stabbed right through her heart and now coughing out blood.

The child she protected stared at her bleeding body and runaway without even a bit of 'thanks'. But the girl didn't get angry nor felt regret about it. She was just glad even though she was in the brink of death that she was able to save someone.

" What's your name?" She heard a voice ask.

A figure fell from the sky (or specifically, the dragon's back). He had dark black hair, red eyes, a white complexion, a teenage height but a baby-face appearance

" Lucy, Lucy Heartfilia." She replied, still vomiting blood. She decided that if she would die then she would at least make sure someone remembers her name.

" Why did you save that ungrateful child?" He asked again coldly.

Lucy cocked her head to the side " Because it's good to be alive, I guess...to feel the morning air, to make friends, to go through tons of adventures and a lot more."

" Then why didn't you save yourself?"

" Well, he's still young. At least, younger than me. And he'll go through a lot more than me so he'll need his life."

Zeref, for the first time smiled slightly. It was the first time he saw someone so interesting in his entire life. Too bad, she's going to die...unless...

He placed his hand on the part where her beating heart is supposed to be, instead clawed out by Acnologia. " I shall give you another life, Lucy. Half of my heart to replace your dead one. I have given you a new life, now live until we meet again. However, the path you now walk on will never be the same again, but..."

Lucy ended up not being able to know what he'll say next because after the Dark Magic surrounded them, he and Acnologia disappeared, leaving only her unscathed and everyone else in that town dead.

Lucy knew if the Magic Council sees this, they'll treat her as the suspect which she may or may not be it. Taking no time at all, she quickly ran away from the town, to the forest and somehow get home. Hoping that the fact that all that happened and that she maybe the one who killed those innocent people was just a nightmare.

Since that time, rumors of a child saved by Zeref spreaded all throughout Fiore. The corpses of the villagers were found but there was nothing else to prove that the child existed. Finding no evidence at all, the Magic Council left it at what is originally was, a mere rumor.

No one even thought that the child had runaway and was living among them. Nobody noticed that the 7-year-old Heartfilia heiress had a sudden surge of magical power inside her.

That's right, No one knows of this secret but you and me.

That I, Lucy Heartfilia, am the Dark Child.
