The Fallen Archangel Lucifer watched the mortal world from the Pit of Hell, and lamented the loss of the Kingdom of Heaven. Lucifer's own brothers, the Archangels Michael, Uriel, Gabriel and Raphael captured him and imprisoned him in the Pit of Hell, along with the tens of thousands of Rebel Angels who joined his foolish cause. The Rebels lost their foolish war, and so much more. The Fallen Angels would never be allowed back into the Kingdom of Heaven, and were banished for all time. Lucifer felt it was a harsh punishment...
Once upon a time, the Archangel Lucifer hated Humans, and felt that they were given too much, compared to the older, wiser and much wore worthy order of the Angels. The Maker favored the Humans, and more than a few Angels felt jealous, though Lucifer was the only one who voiced his discontent. Lucifer Rebelled against the order, and led an army of Angels against the Kingdom of Heaven. Outnumbered and outmatched, the Rebel Angels fought bravely but still lost. They were driven from the Kingdom of Heaven.
After spending eons in the Pit, Lucifer regretted his Rebellion. Why should he pay for all eternity for a foolish mistake? There are Many other worlds and dimensions, besides Earth, Heaven and Hell, and the Fallen Angels watched them with envy. When an inter-dimensional portal opened, Lucifer slipped through it and returned to the mortal world in the guise of a tall, good-looking Man with skin of a rich mahogany hue, and a shaved head. Lucifer walked around the lush jungle which covered what would one day be known as the Middle East, hundreds of thousands of years into the future...
Lucifer saw Adam and Eve, and found them quite comely. The Humans were nothing like he'd imagined. Once upon a time, Lucifer hated Humans and felt jealous of them. Now, he found them positively attractive. Adam was tall, muscular, brown-skinned and dark-haired while Eve was also tall but slender, with alabaster skin, red hair and blue eyes. After being driven from the Garden for their disobedience, the couple found themselves alone on Earth. Lucifer sensed an opportunity, and approached them. Claiming to be a sympathetic Angel, Lucifer displayed his wings, and thus reassured the couple...
"I miss the Garden, but freedom is a wonderful thing," Adam said to Lucifer as he dined with the couple at their camp. Lucifer thanked Eve for the roasted rabbit she served him, and admired the couple. The Humans were more resilient and creative than Lucifer thought they were. The Fallen Angel thought that the Humans would fall prey to the ferocious beasts that ruled the wilderness, such as saber-tooth cats, woolly mammoths and the like...
"Do you miss Heaven?" Eve asked Lucifer, and he smiled and nodded. Lucifer definitely missed Heaven, but he also valued his freedom. While Lucifer got to create his own kingdom in the Pit of Hell, the grumblings of angry Rebel Angels, the laughter of demons and the savagery of monsters was not something he craved. Lucifer found the planet Earth a much more appealing place, and if he didn't have to go back to Hell, then so be it. Even the Devil can change his mind sometimes...
"I'd rather be here with you, my new friends," Lucifer assured both Adam and Eve, and the couple looked at him and nodded. In those days, Humans had no weird notions about sexuality. The complex categories such as heterosexual, bisexual, homosexual or lesbian never occurred to Adam and Eve. In their time, people made love, and that was that. The couple looked at their new friend and found him attractive, and then invited him to their bed. Lucifer simply couldn't pass up such an offer...
