This is a sort of chapter trailer for this story.
Recently, I've started watching Fairy Tail again & I've noticed a few things & made theories out of them. Mainly around Lucy's family history, her involvement with Zeref's plans, & her ancestor, Anna Heartfilia with a certain Dark Dragon Slayer.
And...I have a theory!

Theory: I believe that there was somewhat of a history with Anna & Acnologia than what the anime wanted us to know. I imagine that Anna & Acnologia knew each other, before Anna met Zeref, & that Anna was able to help calm a bit of Acnologia's lust for blood & destruction. Also, I noticed in Fairy Tail Final Season Episode 319, "Compassion", in a flashback of Anna & Layla that when Anna was talking about passing a book to the next generation. We don't at all see what Anna's kid looks like, not even a speck of blonde hair which is a Heartfilia trait, along with the other generation until they reach Layla. Coincidence, I THINK NOT! I think that maybe something happened to Anna, like a dragon killed her while she may have been pregnant with hers & Acnologia's baby, & Acnologia finally lost all of his humanity & began to kill again, except this time, Anna couldn't save him. Also, isn't it strange how Lucy was always involved with almost anything to do with Zeref or the mere mention of him. It was almost like she, herself, played a part in Zeref's plans...Anyway, anyone could see that Lucy is a very powerful mage, maybe more powerful than Anna, & she was able to rewrite the book of E.N.D, something a human or mage should have died from. But she didn't, she only had a cursed mark for a while & she was all better later. Also, in episode 49, "The Day of the Fateful Encounter", when Lucy was seemingly Natsu on the train & Wendy passed by, Lucy had snapped her eyes wide & looked straight at Wendy's direction. As if she sensed something familiar or perhaps, a pull...Lucy looked almost monotone when she saw Wendy, almost emotionless. Plus, Cana said in the episode. "..you'll have a fateful encounter today.", which obviously meant Wendy, but why was it only Lucy that received this. How come it wasn't Natsu, a fellow Dragon Slayer, & even though he didn't know until later that Wendy was a Dragon Slayer, why was Lucy the one to receive a fortune. Why does she have a connection to a Dragon Slayer..?

Now I know that some people will think it's a ridiculous theory & that there really isn't any clear evidence, but I firmly believe that there was something going on between Anna & Acnologia in the past, especially since Hiro Mashima has a way of foreshadowing Fairy Tail backstories. but I firmly believe that there was something going on between Anna & Acnologia in the past. Along with the possibility of Lucy being the granddaughter, more like 400+, of Acnologia.

Anyway, enough of that, the reason I brought this theory up is because it has to do with my first ever fairy Tail story!
This is sort of a trailer chapter, a preview of what the story is about & what might happen in it, hope you all enjoy it!

Mercy, Mercy...
Chains all wrapped around me (Around me)...

"What just...what is it that you're not telling me, Anna..?"

"...It's complicated, Lucy. You wouldn't understand..."

Try to break free...
From the dark part of me

A petite, pale right hand clenches it's fist, a dark blue makes its way to the face.

Mercy, Mercy...PLEASE
I forget myself (Forget myself).
And my good nature...

A flash of blood sprayed the walls.

A young woman's hand dripped in blood.

A young woman leaned against the wall, sliding down it & staring at her right hand...Staring at a bit of blood on the tips of her fingers. A chocolate, brown eye stared at the blood that was on her fingers.

An almost sinister smile crawled on her face at the sight of blood, but it wasn't hers...

When I let temptation get the better of me...
Oh, Mercy me...

A woman stared. Before looking down, seeing the itching twitch of her lover...

A pair of drunk wizards were passing them as she stared at him.

All I see-e-e-e-e is a MONSTER...in me-e-e!
All I see-e-e-e-e is a MONSTER...in me-e-e!

A mirror, shined by the moonlight, a woman stared into it. But, the reflection showed a man instead.

A petal-like mouth clenched it's teeth. A hand leaned back as brown eyes were filled with tears. But, these tears held despair & betrayal.

A hand smashed the glass...

She is made of skeletons,

An older woman stared at the smiling young teen.

I tried to bury Long ago.

She clenched her fist as tears began to fall silently from her eyes...

"I'm...sorry..." The older woman spoke softly.

No one heard her sorrow...

Her fingers are always on the trigger.

A teen walked past the older woman, already knowing that the older woman flinched as she passed her.

Oh, no no no

It was almost like his touch...

All I see-e-e-e-e is a MONSTER...in me-e-e!
All I see-e-e-e-e is a MONSTER...in me-e-e!
Monster (3x)

Blood everywhere...

Screams...

Tears...

The Monster is me!
Monster (3x)

"Am...I really going to be, like...this..?" Hesitantly she spoke, looking at her reflection in the lake.

Tears dripped from her eyes, landing on the reflected pool of the lake. The reflection showed the same man, who's tears headed to the lake reflection.

Creating a ripple, shaking the image

I want to be the hero you need,
I want to be brave,
I want to believe...

Blonde hair figure stared at her hands, sorrow & fear displayed on her face.

Gold keys shined in the moonlight, the only source of light in the dark room...

But I take all the light,
And make it go black

A single darken brown eye connects to a wide eye, almost tearful, black onyx.

An emotionless eye connected to an eye full of emotion.

Who could love somebody like that?

A shine almost broke through the emotionless one...

All I see-e-e-e-e is a MONSTER...in me-e-e!
All I see-e-e-e-e is a MONSTER...in me-e-e!

...But, the flick was gone in an instant.

And so was she.

Monster (2x)
A Monster in me-e-e

Fire in the air...

Warrior cry's...

White flashes...

Blood...

Tearful moments...

Heartbreaking tears...

Love...

The truth...

All I see-e-e-e-e is a MONSTER...

A young teen's eyes snapped open; red eyes glaring at the man in front of her...dark blue marking coming from her right hand & heading towards her face, but making it into 2 sorts of beast-claw marks.

"So, it's finally time. Let's see what you can do,..." A man said, sounding twisted; "...cursed Heartfilia~" The man finished with a twisted smile.

Both of them charged at each other, a glaze of fury in each of their eyes.

Each raised their hands, the female with her right & the man's left, both punched at each others hand at the same time-

Cut to black...

A Monster...in me~
