The Seer's Crystal

Now that we know there's no truth to the Black Knight's stories, we must find a way to connect him to the murdered knights. I know a way to reveal the truth about how they died, but it requires a rare material. We must gain a seer's crystal, found only among the unbound seers who congregate near night elf ruins in the Forlorn Woods in the central part of Crystalsong Forest. Find one of these seers, ‹name›, and bring me the crystal it holds.
