"You'll stay in the sun till you're black as coal if Adar wills it."

"For Adar, then. But not for you!"

"But they ransack village after village, toiling nightly to find it for their leader."

"One the Orcs speak of with near-worship, even reverence, if Orcs were capable of such a thing."

"It seems Morgoth has a successor."

"Adar."

"Why would Orcs refer to their leader by an Elvish word?"

"Sauron was said to have many names in days of old. Perhaps this is one of them."

"Bring him to Adar."

"Adar! Adar! Adar! Adar! Adar! Adar! Adar! Adar! Adar! Adar! Adar! Adar!"

Is Adar:

. Anatar?

Adar sounds like Anatar. Is he the 'Lord of Gifts'?

. Father of the Orcs?

Adar means 'father' in Elvish.

. A leader of the Orcs?"

Not Sauron, but some form of in-between leader who serves him?

. Someone else?
