Find Sethir the Ancient and bring back any clues that you may discover to Syurna.
We believe there is one being that may be able to help us understand what is happening to the forests of Teldrassil. Unfortunately, getting the creature to cooperate has proven disastrous.
He hides on a branch at the outskirts of the Oracle Glade. All who have so far approached the satyr, whether through force or diplomacy, have met with doom. Perhaps stealth is the answer, <name>.
Find what Sethir the Ancient carries in his packs and report back to me.
