Bring the Faded Shadowhide Pendant to Theocritus the Mage.
<You hear a disembodied voice...>
Do not be alarmed. I am Theocritus, High Mage of Tower Azora in Elwynn Forest. The pendant you are holding is a method of communication between the Shadowhide Gnolls and their master, Morganth.
Through months of research, I believe I too can communicate through these pendants. If you can hear this message, then my spell was a success.
Bring me this pendant and I will reward you for the service.
