My Heart is in Your Hands

You need to get 5 Desperate Mojo to summon the ghost troll.
When you have them return it to the ghost troll and grab the new quest "Voices From the Dust".
Now move back to main town Amberpine and leave 3 questes and grab 3 new quests, "An Exercise in Diplomacy", "Thinning the Ranks" and "Secrets of the Flamebinders".

You are now going to finish "Thinning the Ranks" and "Secrets of the Flamebinders" south of Amberpine at Voldrune.
