Moriantum is a place briefly mentioned in the Book of Mormon. In the Book of Moroni, Moroni copies a second letter that his father Mormon has written to him prior to being killed by the Lamanites. Among the things Mormon tells his son is the brutality of the Nephites in Moriantum. Having taken many of the daughters of the Lamanites prisoner, the Nephites would take their chastity and virtue. Then they would torture them until they died. Finally, they would devour their flesh. All this they would do as a token of bravery.
