So yeah, this is what popped into my head.
Fierce growls and snarls could be heard from behind the enchanted walls. Screams and cries of many that had become insane and corrupted. Beasts of all kinds and shapes, things that were considered evil and what parents called monsters were locked in the prison.
Thousands' of dark souls… thousands that wished to be let free of their confinement and to rule the stars once again; to corrupt more innocents.
One man took the task of guarding the prison, one man in brilliant shining golden armour with a mighty sword blessed upon him for his courage, his sacrifices to protect the constellations and beyond. Kozmotis Pitchiner was the General who fought with fierce precision and won every battle he fought in.
He stood stoic as he did the best he could to ignore the screaming and the trickery the shadows – Fearlings – created to trick him into believing. He had stood here for so long and he was tired but he would prevail. He would stand guard for his daughter, the only being he truly cared about, to keep her safe.
"Oh my little Sera…" Kozmotis whispered as he stared down at the image of his daughter in the locket she gave him. His heart longed to see her face, to hear her sweet voice once more but he could not leave this place in fear of something going terribly wrong.
"Daddy…" Fear clenched his heart at the whimper of fear, his eyes flashing to the mighty doors that kept the monsters locked inside.
No, no, it wasn't Sera… She is safe… she would be a young woma….
"DADDY! It's dark daddy…" The voice cried out causing Pitch to take a step forward towards the door, his mind screaming at him that it was a trick, another trick. But he longed for his daughter; his little girl was trapped in the darkness.
"No… No! I will not fall for your trickery!" He yelled while clutching his head, trying to ignore the sound of his daughter crying.
"Daddy I'm scared! Their scaring me daddy!" the voice whimpered again causing Kozmotis to scream and draw his sword before charging towards the door.
He slashed at the wood and metal with fierce determination, the sound of his daughters cries filling his mind making him strike quicker and more frantic. He could hear her voice telling him he was close, just a little more and when the large chunk of wood and metal fell he let out a laugh of relief before horror dawned on him as the black shadow began to seep out of the crack.
The fearling let out a cackle before it and many others swarmed Kozmotis, swirling around him as it began to force its way into his body; breaking his mind and driving him insane. His screams echoed through the land and the dark halls of the prison as the monsters escaped while others stayed to corrupt.
A dark laugh replaced the screams as the fearlings disappeared, leaving Kozmotis shaking on the ground. The once golden armour was now gone and in its place was a blackened robe, his golden brown hair and tanned skin was now the darkest shade of black and greys.
"Oh! Ahahaha!" He laughed as he stood, his legs shaking as he tried to regain his balance.
No more was the mighty Kozmotis Pitchiner, in his place was now the more insane and corrupted Pitch Black.
