The Hobbit: An Unexpected Journey"Thrór's love of gold grown too fierce and sickness had begun to grow within him. It was a sickness of the mind. And where sickness thrives, bad things will follow. The first they heard was a noise like a hurricane coming down from the North; the pines on the mountain creaked and cracked in the hot, dry wind. It was a fire-drake from the North. Smaug had come! Such wanton death was dealt that day, for this city of Men was nothing to Smaug. His eye was set on another prize. For dragons covet gold with a dark and fierce desire. Erebor was lost."

"Now, the Necromancer, are you sure?"
"That is not from the world of the living."

"They speak of a Necromancer living in Dol Guldur, a sorcerer who could summon the dead."
"That's absurd. No such power exists in this world. This Necromancer is nothing more than a mortal man. A conjurer dabbling in black magic."
"And so I thought too, but Radagast had seen..."
"Radagast? Do not speak to me of Radagast the Brown. He is a foolish fellow."
"Well, he's odd, I'll grant you. He lives a solitary life..."
"It's not that. It's his excessive consumption of mushrooms! They've addled his brain and yellowed his teeth!"
