Vengence
A vicious, feral growl bubbled up from deep within his throat as his lips pulled back into a fierce snarl. The whites of his eyes bled a ferocious red and his pupils faded into a bright blue. His claws retracted then grew; reaching over two inches long. The wind whipped his dark clothing and silver hair as his prey viewed upon his pale face, now twisted into a horrible mask of hatred. Clouds formed overhead just as he started glowing a pale silver light, and thunder rumbled loudly in the distance. The wind picked up, becoming a powerful gale. The trees surrounding the duo were ripped from the ground with tremendous force and rain came pounding down hard enough to burn the victim's face with each drop. Or maybe it burned because of the demonic creature controlling the awful storm.
Whatever it was, the man was terrified. He had never regretted his decisions until now. Not until he had met that beautiful girl. Not until this monster had come to avenge what he had taken. He wished with all his heart that he had never done what he had done to the young woman, whom he now realized to have obviously been the demon's human. He knew this would not end well for him. He could feel the creature's powerful aura. Stronger than any other he had ever felt during his short life. Strong enough to invoke such a fear within him that he wanted to die…if only to escape the wrath of the demon before him. He knew deep down, in his soul, that the Fires of Hell would no doubt show more mercy to him than what he was about to face.
When the demon spoke, it was barely more than a growl but the message was still clearly conveyed, "By the time this night is over, you will be begging me to end your miserable life. And when that time comes, I will show you no mercy for what you have done. I am going to make sure that when you do die - which will only be after you have suffered as much as she has, if not more – that you will find no peace in the afterlife. I swear to all that is holy that you will pay for this forever." The growl of the beast grew so loud and violent that he could feel the vibrations down to his very bones. He looked directly into his punisher's eyes and watched in paralyzed terror as the demon pounced on his prone form with the bloodlust of a million men and the predatory hunger of a wild animal in his once golden orbs.
