Druids murdered! Who did this? Someone's gonna bleed for this! But first we need to find them.
Find and convince Empoor to tell you what he knows.
I don't know what to make of all of this, but I do know how we can find more clues.
Fine, fine... I'll tell you what I know, but it's not much!
You talk to Empoor, then he and his bodyguard attack you. You have to get Empoor down to 20-30% health, at which point they both stop attacking. Then you can conclude the quest.
This is not a prerequisite.
