The Witch-king has an Idea
"Sir, Witch-King, maybe we can do something with the orcs? I'm not sure what we'd do, but I think we can spare just a few more for something," said Ringwraith #4.
"You think we should send orcs at him? You, who was just an hour ago telling me to stop dropping orcs onto the elves?" the Witch-king said. This was why he hated working with others. Everybody was too stupid and forgetful to get anything done. "Typical hypocrisy, I swear. Go get me an Ád'vîl while I think about this. You're giving me a headache"
Ringwraith #4 rushed off to the Witch-king's medicine cabinet and the Witch-king rested in his comfortable, black leather armchair which he drove in, head in hand.
He better come back soon, the Witch-king thought,
he gives me the most horrible migraines. And that troll, how on earth can I kill that troll? Can I swoop down with my brilliant sword and thwack off his head with one great swing? No, their necks are too thick. Can we smash him under the wheels? No, I don't want any more stains on them. The Witch-king's rest was soon disturbed by the howling of orcs in the distance, and the twang of bows.
Don't tell me those orcs I dropped have followed us!
The Witch-king rose from his seat and wandered over to the rear walls, where down the forest path he could see his seven orcs bellowing and scampering through the bushes, pursued by a hunting party of elven bowmen.
"Ringwraith #4! Get out here!"
Ringwraith #4 ran out of the great central tower with a glass of water in one hand and a pill in the other. "Here is your Ád'vîl, sir," he said. The Witch-king took the pill and swallowed it with a swig of water, then pointed at the orcs and elves. "See those orcs? Those are the orcs I dropped on the elves back at the halls of the elven-king. They've followed us and are being chased by elf hunters. I think we may have found our solution to our little troll problem. Are you thinking what I'm thinking?"
"That we can convince the elves to give us their pocket change to pay the toll?"
"Now, you idiot!" said the Witch-king, and slapped Ringwraith #4 across the forehead, "As the elves hunt the orcs, we can drop more orcs and give them instructions to lead the elves straight to the troll. The elves will kill the troll, and we can be on our way!"
"Sounds like a plan, boss. I'll get on it right away."
(Take it away, Ringwraith #4, I might not get a post in tomorrow)
