The devil's plot
In the beginning, Satan couldn't help but be impressed by this new race God had created. They looked like angels yet were so different, so vulnerable, and the devil was fascinated by the way they lived and died.
For centuries he toyed with the humans, tempting them to sin, always trying to provoke the big man upstairs. He wanted revenge for his exile, he wanted to prove he was just as powerful as God and to do that he needed his own race. Satan's fascination with the humans soon faded to contempt as, although the humans had evolved in their technology and the way they ran their societies and communicated with each other, they still possesed no real powers. They can't run that fast, never learned to see in the dark, they couldn't fly and they died far too easily. In comparison to some of the amazing feats the animals on earth could do, the human body was just so boring. Angels had a very similar anatomy but without the reproducing, the parts were there for enjoyment but no babies, angels aren't made like that. Angels have many abilities a human doesn't, like feeling each others thoughts and emotions, seeing distant places in their minds and transforming into animals just to name a few. The devil wondered why God made them so inferior yet gave them the whole earth to do as they pleased with. He imagined his race to be more like him, a superior race that could claim the Earth for their own.
It was true the devil was a powerful being and fully capable of creating life, but his hate and bitterness hindered his ability to focus all his power into one task and the creatures he created were hideously deformed. They were better, faster and stronger than the humans, and even the angels, but they bore none of the beauty of humans and angels. Satan and his fellow fallen angels were vain and could not bear to look at them so they sent them out into the world to torment the humans, but God had sent a powerful celestial to hunt down and destroy these demons. Creation took up a lot of the devil's time and effort and due to the differing anatomy of the demons, not one of them managed to produce any viable offspring and the population quickly dwindled leaving only myths in their wake. The devil was humiliated by his failure and went into self imposed exile vowing to one day have his army and show the world just how powerful he can be.
It was Satan's good friend Charon who gave him the breakthrough he needed whilst recounting the whole Lazarus incident. Charon was still a bit pissed about that, Satan had heard a million times over a millenia how hard it was to row UP the river Styx to return that man but Satan knew he had been rewarded very handsomely for it and it was his biggest claim to fame so he let the old man ramble on. It was a throwaway comment about how Lazarus gained some of God's power through the resurrection process that grabbed Satan's attention. "How did that happen? " he'd asked the ferryman, who without thinking of the implications of his words, let slip that the secret behind God's resurrections was blood transfusions. On another visit he managed to wrangle more information from the loose tongued captain and the devil was shocked to learn that the man, Lazarus, was made immortal by the resurrection process. So it was possible? And Lazarus was just a mere human before his death. Excitement and ideas coursed through the devil's body and mind, he had a group of humans who had devoted themselves to him and he couldn't wait to test out this method on them.
The devil picked his strongest, most loyal subject, who was more than happy to potentially sacrifice himself for his dark lord's great plan. Charon had warned it would take almost all of the devil's blood and life force and would leave him weak and drained for sometime after but he was prepared to do whatever it took to get his army. In order to be resurrected, the subject had to die and he enjoyed a night of debauchery in case it was his last. Before the process a dozen naked, sobbing women kissed him passionately all over his ripped body and begged him to make it back to them for more fun times. Satan thanked the young man for his loyalty and made promises of immortality, glory and many many women then bit into his neck and drained his blood. After the death the heart had to be kept beating to help the new blood fill the body, a naked lady with full breasts had the honour and provided a wonderful show for the men. The women howled in pain at the waning of their master and the death of the subject screaming for them to return.
For 10 days, his loyal subjects kept vigil by his unconscious body willing their master to return to them and see his success. The women danced naked around him singing songs of debauchery in voices that could rival the angels, guiding his unresponsive hands to their bare skin and whispering promises of passion filled nights and days if only he were to return to them. When he finally roused the girls screamed with delight and some fainted. The first thing their master did was enquire of his experiment and the subject was summoned to the room. When he entered he was shirtless and flagged by his harem, who were shoving each other out of the way to kiss his neck or touch his muscular chest. He walked with a confidence Satan recognised from himself and he felt a connection so strong with this man that he instantly knew it had worked.
The young man approached the dark Lord and knelt before him. "Master I thank you for your gift, I pledge my body and soul to your cause forevemore".
"Rise child we are equals now, you have been reborn a new man and we will rename you Adam".
