Chapter V: Sauron and Saruman
In the Tower of Orthanc in the Palantir room
"How many of you are there?" asked Saruman.
"We are the only hobbits in the Fellowship." lied Frodo.
"I ask again, how many of you has Gandalf recruited for this...this foolish attempt to oppose Sauron?"
"We told you already. It's just us." said Pippin.
Saruman stood in his black throne of iron looking down at the three halflings restrained by several of his Isengard Orcs.
"I may have trusted you, had I not known that this Fellowship involved Gandalf. What happened to him, hm? Tell me all I wish to know and I may set you free or at least ensure you're not given as food to the Orcs."
"He fell. In the darkness of Khazad-dum he fell fighting a demon made of shadows and flames." said Frodo.
"A Balrog of Morgoth? And did Gandalf defeat it?" asked eagerly Saruman, for as jealous as he was he wanted Gandalf to be humilliated and defeated by that terrible foe.
"Gandalf had attempted to keep the demon away from us and to this end he put a spell on the bridge and once that horrible creature stepped on it, the structure crumbled beneath it and it fell, only to throw it's whip and grab Gandalf with it in the abyss below."
Saruman laughed for he was glad that Gandalf was apparently no more and would not trouble him and his Master again.
"My Master Lord Sauron will be pleased to learn of this. And you say that he fell with the Balrog?" said Saruman.
"He did. That was the last we saw of him." answered Merry.
"Gandalf the Grey? I think it doesn't suit him. Rather Gandalf the Fool. Yes, that fits him right. " amused himself Saruman.
A shriek was heard and then the terrible growl of a fell beast outside the Stone-tower. Then the doors of the chamber burst open and Lurtz came in.
"Milord, a beast has come carrying a Black Rider who claims he awaits ye. Are ye aware of anything of this sort. What should I tell him?" asked the Orc.
"Tell him to wait. I will be with him shortly." said Saruman and he ordered the Orcs to take the hobbits back to the Black Rider before he entered his balcony from where he saw the army gathered to answer Sauron's summons.
He began: "A new power is rising! It's victory is at hand! Soon, the land will be filled with the blood of Rohan. March to Edoras! My fighting Uruk-hai, you do not fear pain nor death! You will taste Man-flesh! Leave none alive! Leave nothing standing! And let them know that nothing can contend with the wills of Sauron and Saruman! To war!"
He turned to see Lurtz and Uglúk behind him.
"I leave you two to command my army. You will lead and begin the assault. I have prepared bombs with blasting powder inside my Alchemy Chamber. When they are lit up, they will explode and destroy the stone walls, allowing our Uruk-hai to storm upon these Rohirrim brigands. I trust you will not fail me." he said before descending down the stairs to where the Black Rider and his Fellbeast awaited him.
Four days later:
Saruman stood kneeling before the Dark Throne of Barad-dúr as the armored and cloaked shadow of Sauron said: "Fell with a Balrog you say. What a fitting end for Greyhame. He shall trouble us no more. Perhaps Morgoth had done right to make these demons. They are useful and they once obeyed me as well. This one seems however to have wandered off and I was not informed of it's existence in Moria. Either it was acting on it's own accord or otherwise he had remained faithful to Morgoth. Both of them fools, for Morgoth will never return. And even if he does I have no intention of bringing him back. He is weaker than me now. Far weaker. Why would I bow to a lesser being whom I in the beginning had admired. Then he was strong and powerful and worthy to call himself Dark Lord. But now? I am the Dark Lord! The true Dark Lord! And to think that they once called me 'Servant of Morgoth'. I served Morgoth once but our goals were never aligned. He was a nihilistic mad-man who destroyed because he could not control. I however have the power and will to control Arda and thus I seek to rule it not destroy it. If he had won, we would have become rivals and I would have won in a fight, for he was weak and arrogant. That Fingolfin Elf managed to wound him. An Elf, Saruman, an Elf! Think what a Maia such as I would have done to him!"
"You would have surely beaten him, my lord." answered Saruman.
"I would have made him, a Vala, bow before me. Even Glaurung the Father of Dragons, Tevildo the Prince of Cats, Draugluin the Sire of Werewolves and Boldog the Chieftain of Orcs obeyed me and served as they served Morgoth. Only that wretched Gothmog the Lord of Balrogs rivalled me, but only in rank not in power for he feared me and in Morgoth's absence it was I who ruled Angband and even that demon would acknowledge me as his lord. I am King of the World not Morgoth! And that is why all must bow to me and worship me alone. But enough of that. You have proven yourself loyal, my servant. And I hear that Rohan is already weakened."
"Rohan will fall, my lord. Soon enough. All shall serve you and act according to your will." said Saruman.
"You deserve your reward, Saruman. You shall be my Hand when I rule Arda. " echoed the voice of Sauron.
"I thank you, my lord. " said the respectful voice of Saruman.
"You deserve it. All shall bow to us, my servant. All shall bow to ME! Middle-earth will be MINE! Arda will be MINE! It shall all be MINE!" said Sauron.
