Ancient of Days (End of Perfection) and the Fall of the Watchers

Some of the main characters in the Ancient of Days: End of Perfection are loosely based on biblical history. The fictional character “Archael” is inspired by Genesis 3: 24; after the ostracism of the first parents from Eden. It is said cherubs were posted at the East entrance, and in their possession a flaming blade of a sword “to guard the way to the tree of life.” Whether more than two cherubs were stationed there is not stated. Genesis 6: 1-4 goes on to tell that some of the sons (angels) of the true God materialized, married women and continued to have relations with the daughters of men and they bore sons (demigods or Nephilim) to them, “they were the mighty ones who were of old, the men of fame.”
The Books of Enoch also talks about Fallen and Unfallen Watchers. The first part of the book devotes much of its attention to the Fallen Watchers whose duties seemed closely unanimous with the duties of the cherubs placed at Eden. The Aramaic irin “watchers” is referred to as “angel.” These Watchers, the angels soon began to lust after the daughters of men at the prodding of their leader Samyaza. Imprecations were sworn and masse unnatural relations were formed as suggested in Genesis 6. This prompted an era of wickedness and undue enlightenment to mankind inspired by the Fallen Watchers. In the novella this enlightenment is likened to giving a knife to a baby as a plaything because the enlightenment inspired by the Watchers were to be discovered piecemealy over time by humans, not introduced to humankind all at once. This inevitably brought the Great Deluge and the damning of the Fallen Watchers.
Ezekiel 28:13-15 goes on to tell about a dirge where the king of Tyre is likened to a cherub that was once “in Eden, the garden of God,” but who was stripped of his beauty and made as ashes upon the ground. “This is what the Sovereign God has said:‘You are the anointed cherub that is covering, and I have set you. On the holy mountain of God you proved to be. In the midst of fiery stones, you walked about. You were faultless in your ways from the day of your being created until unrighteousness was found in you...I shall put you as profane out of the mountain of God, and I shall destroy you, O covering cherub.” This scripture is suggestive of a righteous cherub (or Watcher) becoming a turncloak and if so supports the Book of Enoch. 
The character of “Lucifer,” Satan the Devil, the chief Adversary of God (the Ancient of Days) as portrayed by the novella is controversial. As Lucifer being the “ruler of the demon” (the Fallen Watchers) did not suffer the fate of his counterparts: banished from the celestial abode and reserved for judgment. It is even suggested Satan the Devil is Samyaza. However, It should be noted that Lucifer (Satan) is not mentioned as being among the first group of Watchers who fell until a later fall. Testifying to this is the Book of Job and Revelations.
The Book of Job talks about a meeting that occurred in the heavenly abode and “the sons of the true God entered to take their stations before the Ancient (God) of Days, and Satan also entered among them.” (Job 1:6) This would mean Satan still had access to the heavens well after the Great Deluge since this meeting must have precipitated during Job's trial at about 1613 BC, well after the Great Deluge. Besides, nowhere is it said in the bible that Satan was among the Watchers who first fell, but until much later in the Revelation of John.
In the Revelation of John, Jesus Christ, after his earthly life took Kingdom power with every power in subjection to him granted by his Father. “And war broke out in heaven: Michael and his angels battled with the dragon, and the dragon and its angels battled, but they did not prevail, nor was a place found for them any longer in heaven. So down the great dragon was hurled, the original serpent, the one called Devil and Satan, who is misleading the entire inhabited earth; he was hurled down to the earth, and his angels were hurled down with him.” (Revelations 12: 7-9) Satan is hurled down out of heaven to the earth during this second fall, no longer having access to the heavens, as he did prior and in the days of Job and for centuries thereafter.
However, it should be noted that the Lucifer (Satan) in the Ancient of Days: End of Perfection is a fictional one as the novella is a work of historical fiction.
