This quest was marked obsolete by Blizzard and cannot be obtained or completed.
Find Ol' Emma in Stormwind and see if she is in fact Emma Felstone. If she is, then perhaps she'd like the package Janice Felstone made for her.
My name is indeed Emma Felstone - you're the first person in years to call me that. Who... who are you?
You say you knew... my sister?! Is she still alive? Who am I kidding, of course she isn't. When the plague broke out in Lordaeron, I had come to expect the worst. So many of my family died... or worse. Here I am now, crazy Ol' Emma, all alone. What are you, a grave-robber or something? Looking for your next target?
