Nymue Elethiel

If you talk to her and have not completed the quest she will say:
 * Nymue Elethiel: Umm, it's, isn't it? I heard you're the person to ask for help solving difficult problems. If you're not too busy, could I speak with you about this ... issue I am having?
 * Nymue Elethiel: My name is Nymue Elethiel. I'm a Wizard who collects magical artifacts and I've, well, sort of lost one.
 * Nymue Elethiel: It's kind of a long story, though. Would you mind coming with me to my tower? I'd be more comfortable explaining the situation there.
 * Nymue Elethiel: Ugh, just imagine if any of this got out. How embarrassing!
 * You: Lead the way. (Quest Begins)
 * Nymue Elethiel: Please hurry! The longer the artifact stays missing, the bigger this problem gets!
