Locate the other half of the Good Luck Charm somewhere on the Felstone Farm in Western Plaguelands and reassemble it. Give the Good Luck Charm to Janice Felstone on the Felstone Farm, Western Plaguelands.
The ramblings of the poor ghost continue:
"I'm so cold, John. Bring me your charm, and we'll be together! Quickly John, before the plague comes to change us into hideous beasts! I can't see you John... but I know you're near. I feel you near me."
Perhaps if the second half of the charm was found and reassembled, this would constitute what the spirit of Janice Felstone is seeking.
