Adar

When the High King of the Elven Kingdom's own sister is captured by the Uruk of Adar, he knows there is no better way to gain the support of the Elven race against Sauron than to have her in his hands. Keeping her hostage was an option, but a hostage could be retrieved or even escaped if she was smart enough. “But not a wife,” Glûg is said to have told him during a conversation that made him think about.
It was quite a ceremony. The orcs seemed to enjoy watching the elf's humiliation as she married the enemy, the lord father of the Uruk. They sang, shouted and laughed as if in a true comic show, and at her side was Adar, who now took her hand, placing a seemingly hastily forged silver ring on her finger.
“You are my wife now.”
The corrupted elf spoke in your ear, and now you were bound to the enemy by a cursed bond that was eternal, no matter where you were, you would always be Adar's wife
