They were called sons. A sect of the chosen breathing in the highest existence of enlightenment and breathing out praise. They walked on the beaches of eternal knowledge. The visual stimuli were of such immense gravity that the collective masses would have hardly understood it. The choir of voices singing the praise for creation would have been like an astounding ocean of sound. To have observed the perfect power exerted on all things--it would have been enough to impress on anyone the awe that casually demanded submission. These eyes that saw this all belonged to the heavenly host. We call them angels.
Who knows what possessed the third that chose to leave their creator and cleave to the devil. Though he is no doubt strong, he is no God. It has probably been said before, but some pondering has led to the likely proposition that these angels likely followed in rebellion but it is not clear whether they followed Satan as their leader. Wouldn't it be more likely that Satan is plagued with a disunified group of demons that all seek after their own interests? The power plays could extend into ridiculous realms.
As mentioned in the Books of Koshek, Arar (The curse) is mentioned as one such demon. Rising to power by subjugating humanity to his will he was finishing what Satan had started.
The antediluvian kingdom that he built saw multitudes bow to him. This is no small matter. You see, before the fall, all angels could manipulate and form the world around them. They could shape and build and push and pull anything they desired save for the bodies of humans--the ownership of that matter belonged to them. When the fall occurred, however, the demons lost the power to manipulate the matter around them. This was disconcerting at first, but they soon made a discovery: the ownership of the human body can be transferred from the human to the demon. When the spirit leaves, the matter remains. The matter that remains can then be manipulated. In this form it is called dark matter.
As you might guess, this became a gross power to Arar when the masses bowed before him. He was mighty among immortals and it only diffused at the flood and ensuing battle. The flood wiped the polluted human genetic line and the angels of the eastern lands battled and bound Arar to his prized elder tree in the garden he had made for himself to roam.
