Summary
“I asked for a handsome reward in exchange for Finrod Felagund’s life,” the man called out across the distance. He was tall, though not as tall as her brother, and dressed in swathes of black and grey, a loose hood shielding most of his face and hair from sight. “What do you bring me in exchange for him?”
“Galadriel, no—” Finrod began, but Galadriel cut him off.
“—Myself,” she answered his call, though it did not sound as assuring out loud as it had sounded to her before she left her home to make this perilous journey to come save her brother.
The black-robed figure chuckled in response. It started low, but it reached the distance all the way toward her. He grasped Finrod by the neck of his tunic, yanking him back. “What would I do with you?” he threw back at her. “You’re hardly a fair exchange for the warrior I hold in my grasp.”
During the First Age, the War of Wrath changes course. On the island of Tol-in-Gaurhoth, the Isle of Werewolves and one of Sauron’s former strongholds, is the seat of the Necromancer’s power. Instead of sending his wolves out to kill Finrod after capturing Felagund in his dungeons, Sauron demands an exchange for his life. Galadriel offers herself.
