'STOP IT!!'

'Where am I?' Would be an appropriate reaction from someone waking up in a cell.
But not me.
I've woken up here many, many times.
This is my cell.
'(Y/n) (L/n)' should be written on the door I've been here for so long.

My mother gave birth to me in this cell 6 years ago, and everyday since then I have been stuck down here, repeating the same exhaustingly boring cycle.
My father trapped my mother down here when she was 5 months pregnant with me and she's been stuck here ever since.

My sister and father are safe above ground living their best lives, without us.

They are safe because I am not there with them. Without me ruining there lives.

My mother is stuck down here with me because I'm a monster and she created me, because my mother had an affair and I was the result of it. Father wasn't happy and cursed mother to an eternity of pain and suffering. He said he would begin with her not being able to leave me alone, I would be her burden. She had to endure seeing me every day, being a constantly reminder of her infidelity.

I'm a monster because I have one (e/c) eye and one (f/c) eye, and because I have magic. Father says nobody should have different eye colour and that it's a curse. From the day I was born my father told me how I was ugly and deformed.

My mother has been here with me the whole time and she is getting pretty sick now, every day she's getting weaker and weaker. Father says because she's been stuck with me, that I've been killing her slowly, I'm evil, I'm draining her of her sanity and her life, he also thinks she deserves it.

But the real evil one is my father for trapping the two of us down here for so long. My mother shouldn't have to be here. It's not her fault I'm like this, she shouldn't be punished for my existence. Sure she made a mistake but we all make mistakes. I don't quite understand what an affair is but I'm sure she shouldn't be trapped here against her will because of it.
I promised her when we got out of here I would beat up dad for hurting her, and that I would get revenge for the terrible things he's done.
But I'm not sure mum will ever get well enough to get out of this hell. She's been getting worse and worse since I was born, every single day she looks more and more sick so it's up to me to get her out of here!

"I will protect you mumma"

-later, (Y/n) pov-

"(Y/n)!! Wake up!" I hear a loud voice boom, instantly waking me from my dream.

"Yeah, yeah, I'm up" I mumble, laying back down and yawning heavily.

"Come on lazy bones, you'll never be able to break a mountain if you're sleeping" the voice says loudly in a joking tone.

"Awh (dragons/name) you're so mean!" I yawn and force myself to stand up, whining in a childish tone. (D/n) just giggles at me.

"Is poor (Y/n) tired?" (D/n) says in a mimicking voice. 
I laugh and hug his/her large foot, nodding.
"Bully" I say holding back my laughter so I could speak, and let go.

(D/n) has been looking after me since I was 6 years old. He/she found me walking alone in the woods and took me in.
He/she isn't all that big for a dragon. He/she is a cute, little size. He/she hates it because I tease him/her about it but it's okay because I'm small too, (d/n) says I haven't grown fully yet.

I've been studying the art of dragon slaying magic with her/him for 2 years and I've learned a bunch of new spells and attacks!
I really like being with (d/n), he/she is like a parent to me.

Because I already knew a little bit of magic it was easier for me to learn all the other spells I needed to know to be an elemental dragon slayer.

I know that (d/n) will be leaving me soon and I only have a few months left until I am on my own again so I am trying as hard as I can to master all of the spells she/he is teaching me.
I've been learning pretty quickly according to (d/n) but he/she still refuses to teach me spells that could harm others. I don't know if I will ever learn more dangerous spells, ones that are used to injure. I know a few minor ones from before I met (d/n), and he/she has taught me basic attacks like how to break a mountain in half but I'm not strong enough to even leave a scratch in the mountain. If I had to fight someone I don't think I would be able to win again.

-current time-

I sit up instantly, a loud sound pulling me from my memory.

Thunder.
I hate thunder.
I hate storms.
Why does it have to be storming?

I roll over and pull the blankets up, snuggling into their warmth tightly, trying to vanish inside them. I shut my eyes and sigh loudly, trying to block out the sound of the thunder but to no avail. A cold wind blows through the cave and makes me shiver slightly, the blankets not providing enough warmth to protect me from the harsh wind.

"I miss you d/n" I whisper to myself. He/she always new how to take my mind off the bad things in life. I can hear Luna, my exceed, snoring ever so quietly beside me.

'I wish there were more good people in the world'
