So I had to do a conclusion to a stupid story, that with the help of me, just became awesome.

Nikolai ran full force towards the demon with the broken crucifix raised. His arm came down with a heavy force towards the Seynora demon only to hit air.
What? He thought as he looked at the now empty space before him. Where did he go?
A cold, spine tingling laughter rose up from behind him.
"You know its almost funny watching you try and attack me." The demon smirked, "but your struggles are pointless against me, for I am the one and only Lucifer, reincarnated into your dear, naive friends body. Her soul was shattered in the process, which in all reality is only a minor loss when the reward of my return was by far greater."
Nikolai was frozen with fear, completely unable to move. He stared into Lucifer's entirely black eyes. His mind was blank despite his immense struggling to speak.
"No need to try and do anything my dear, your time is almost up anyway." Lucifer raised his  hand, and with a flick of his wrist he sent the frozen Nikolai flying backwards.
Nikolai hit the wall with a loud crack animating around the dark cavern like area. His vision began to blur with a red substance that was now trickling its way into his sight. His head lolled to the side where he saw his arm sticking out at a completely wrong angle.
Nikolai wanted to scream, he tried to scream but no sound would make its way out of his lips.
"You know, its almost a shame that I have to kill you, after all you did do oh so much for me. It was you and Seynora that helped me rise up and thanks to her I am now here standing before you, but atlas, it is not enough. See, I am a powerful being who needs more then one mere mortal life to survive."
Lucifer was looking at Nikolai as he slowly glided toward him. He bent down and ran Seynoras hand down the side of his face.
Nikolai tried everything in his power to move but with nothing to show for it.
Lucifer was inches from his face. A greedy smile playing on his lips. A sharp pain ripped its way through Nikolais body, spreading from his chest through out all of his limbs. His vision began to fade out and everything went black.
His body became numb and he began to feel himself diminish. As he began to fall into the ever ending life of eternity, he heard a deep maniacal laugh in the far off distance.
