Father Urhney the hermit priest is a grumpy NPC who lives in a small house on the southern side of the Lumbridge swamp directly next to the mine. He is involved in The Restless Ghost quest. The Priest of Lumbridge refers to him as a friend and expert on ghosts.
During the course of The Restless Ghost, Father Urhney gives the player a Ghostspeak amulet, which is required to communicate with the ghost in the quest. If the player loses the Ghostspeak amulet before finishing the quest he will provide the player with a new one.
