Go back to the church in Lumbridge. Next to the church is the graveyard with a ghost floating around. Talk to the ghost (you don’t necessarily have to buy DFO Gold wear the amulet to talk to him).
Tell him you can understand him. He’ll tell you of why he can’t rest in peace because some warlock has stole his head. He says it was a warlock that lives in a big tower in the sea southwest of here.
By this, he means the Wizard’s Tower. Before heading there, make sure that you’re prepared to fight a level 19 skeleton.
