米那斯魔窟
In "The Lord of the Rings", "Morgul" is the Sindarin elvish word for "sorcery." The word is used in frequent association with the Nazgûl and their leader, the Witch-king of Angmar. The poisoned blades wielded by the Nazgûl were known as Morgul-knives, the land of the Witch-king in Mordor was known as the Morgul Vale (from which the Morgulduin river flowed), and his fortress there was named Minas Morgul.
