Eleanor's Necklace is a unique piece of jewelry in Divinity II: Flames of Vengeance. This necklace can be acquired after completing the quest Bark up the Right Tree to gain access to Crow's Nest. You'll find the necklace in a small box at Henry and Eleanor's House, southwest of Crowell's House. The necklace is needed for both Reminiscence Of The Past offered by Ricky at the Phoenix Inn and Sinister Motives offered by Astridax on Lanilor Lane. You can turn it in to complete either quest, failing the other.
