Speak to the strange raven then follow it to Ghostclaw.
Speak with Ghostclaw.
Meet with Ghostclaw in Thundering Steppes at ( 746, 2, -704 ) Copy/waypoint 746, 2, -704.
Enter the solo instance called Ring of Karana next to Ghostclaw.
Use the item in inventory to collect the quest items. Warning: the item has to be used on a wounded mob (50% or less) and there are only 7 in the zone. They were actually called Wracked Essences for me. If you, like I did, kill some before you get to use the Talisman, just pop out and back in again and you'll have more.
