The Restless Ghost Quest

Start this quest in Lumbridge Castle. Speak to the priest in the small church in Lumbridge, and he will tell you of a ghost in the graveyard. You can visit the ghost now, but he will only moan at you. You need an Amulet of Ghostspeak. You can get the amulet from an old hermit who lives in a swamp south of the castle. Then return to the graveyard, put on the amulet, and talk to the ghost to hear of his plight. He cannot go on to the next world because his corpse has been defiled, and it's skull has been taken away. The skull is in the wizard tower, which is over a long bridge near Draynor Village. Go into the basement of the tower and you should find the skull. Be careful when you pick it up, as a level nineteen skeleton will appear from nowhere and attack you! Return the skull to the graveyard and use it on the coffin. The ghost will disappear and you will have completed the quest.
