"I am the Elder King: Melkor, first and mightiest of all the Valar, who was before the world, and made it. The shadow of my purpose lies upon Arda, and all that is in it bends slowly and surely to my will.
But upon all whom you love my thought shall weigh as a cloud of Doom, and it shall bring them down into darkness and despair. Wherever they go, evil shall arise. Whenever they speak, their words shall bring ill counsel. Whatsoever they do shall turn against them. They shall die without hope, cursing both life and death."
- Morgoth, to Hurin, from "Narn i Hîn Húrin", Unfinished Tales
Upon that ship which was cast highest and stood dry upon a hill there was a man, or one in man's shape, but greater than any even of the race of Númenor in stature.
He stood upon the rock and said: "This is done as a sign of power. For I am Sauron the mighty, servant of the Strong" (wherein he spoke darkly). "I have come. Be glad, men of Númenor, for I will take thy king to be my king, and the world shall be given into his hand."
- From "The Fall of Numenor", The Lost Road
"[Sauron's] cunning motive is probably best expressed thus. To wean one of the God-fearing from their allegiance it is best to propound another unseen object of allegiance and another hope of benefits; propound to him a Lord who will sanction what he desires and not forbid it. Sauron, apparently a defeated rival for world-power, now a mere hostage, can hardly propound himself; but as the former servant and disciple of Melkor, the worship of Melkor will raise him from hostage to high priest."
- J. R. R. Tolkien, Morgoth's Ring
6 One day the angels came to present themselves before the LORD, and Satan also came with them. 7 The LORD said to Satan, "Where have you come from?"
Satan answered the LORD, "From roaming through the earth and going back and forth in it."
- Job 1:6, 7, NIV
The rest is just razzmatazz.
