The Minions of Culuthas

A few weeks ago, the Burning Legion moved into the Ruins of Farahlon, thwarting our plans to excavate the site for its artifacts. Then earlier today, I learned that one of their dreadlords, Culuthas, somehow killed off all of the other Burning Legion. He has since summoned in demons that serve him. <class>, I want you to go up to those ruins to the northeast and rid them of their demon infestation.
