Dorthonion

In the fictional world of J. R. R. Tolkien's Middle-earth, Dorthonion ("Land of Pines"), later Taur-nu-Fuin, was a highland region of the First Age, lying immediately to the north of Beleriand, and south of the plains of Ard-galen (later Anfauglith) that extended north to Morgoth's stronghold of Thangorodrim. It is notable in its function as a dangerous stage and scene in the adventures of many major characters in several of Tolkien's books and other works such as The Silmarillion, The Lays of Beleriand, and most recently The Children of Húrin. Similar to the other great forests of Tolkien's legendarium such as Mirkwood, Fangorn and Lothlórien it provides a transitional device in the invented history of Tolkien's Middle-earth and important episodes in the heroic quests of his characters such as Beren, Lúthien, Beleg and Túrin.
