Guru of Drakuru is an achievement awarded for a lengthy chain of quests from a Drakkari Troll named Drakuru. The chain is split into two sections. The first section begins in the Grizzly Hills, the second in Zul'Drak.
At this time, Drakuru is caged in Granite Springs in Grizzly Hills. The player is tasked with obtaining several artifacts for Drakuru under the guise of attempting to cleanse Drak'Tharon Keep. This section culminates in Drak'Tharon Keep upon completing where Drakuru reveals his true motives as an ally to the Lich King. The Lich King promotes him to an Overlord and places him in charge of building a Scourge army in Zul'Drak.
The second section of the chain begins in Zul'Drak. The player obtains a choker from one of the undead Trolls near Ebon Watch. Upon delivering the choker to Stefan Vadu, the player goes through a series of infiltration missions into the necropolis of Overlord Drakuru, Voltarus. This section culminates into a final battle with Drakuru on top of Voltarus.
