The Eryn Vorn (S. "Black Wood"; Du. "Coit Du" Os. "Urnin Morn", Q. "Mornorni") was a large forest on the Cape Vorn, a remnant of the ancient old forest of Eriador and was the most dangerous wild country nigh to Harlindon. This dangerous forest covered most of the peninsula called the Rast Vorn (S. "Dark Cape"), about 560 square miles. The cape was too rugged for most mannish inhabitants, but various tribal relics of the Elder Days still dwelt here, along with Trolls, Orcs, Awakened trees, and other evils driven into hiding by the Eriadorans and Numenoreans during the Second Age. Of the tribesmen, only the Beffraen raided beyond the bounds of the forest into Girithlin and Saralainn. They once had controlled much of Minhiriath during the early Second Age, and hoped to do so again as Cardolan
