They call him the Necromancer, for Wraiths and Shades and Wrights serve him. He is little better than one himself, still recovering from his last, ignoble defeat. Shouldn't he have learned not to engage his enemies himself by now? He had done the same with Huan, and it had worked just as well: namely, not at all.
He still brooded on that loss, on the loss of his Ring, the one thing he needed to make his victory complete. Though never to rule the Blessed Realm. Númenor had taught him that painful lesson. The moment of triumph in hand, then water, tumult, destruction, and death. Drowning was unpleasant.
But the dark years that had followed the loss of his Ring–much of this Age–had been useful. The Nine had always been his principle servants, but now he knew how to wield them most effectively, and how to bind the lesser creatures like them into his service. But now, the anonymity he'd enjoyed as the Necromancer had been stripped away: no longer did they Wise believe he was merely one of the Nine, or some other new Power. They would claim a Dark Power had returned, but in truth he'd never left. Thanks to Isildur, he was still here, two Ages after his former master had been defeated.
He was ready now. Smaug would serve him, if he promised the Dragon fresh meat, and new treasure. None in the North could stand against the powerful descendent of Ancalagon. All that Sauron needed was to find his Ring…and the world would be his.
So, this was inspired by that line from the new trailer: 'A Dark Power has found a way back into the world,' spoken by Radagast. The first time I didn't really notice it, I was too busy squee-ing. The second time though, it bugged me, as really, Sauron never *left* the world, so he can't have found a way *back*. Hence...this.
