Most nations have a language, culture, territory, and history.
They are one of many peoples who have arisen and declined in the history of the West, and now the only reports of them survive among the descendants of their enemies. Lest all is lost forever, I, a scribe of the West, shall tease out what little is known of this people. There are very few references to the folk of Angmar and we hear of them only in relation to conflict with the Dunedain, after they had had come under the malevolent rule of the Lord of the Nazgul. Our Hobbit adventurer's travelled through Rhudaur and saw the ruins of the castles from which they ruled that land, and Bilbo also passed through old East Angmar returning from Erebor, though we have no accounts of that land from him. For at that time the realm of Angmar arose in the North beyond the Ettenmoors.
