Doriath is the realm of the Sindar, the Grey Elves of King Thingol in Beleriand. Along with the other great forests of Tolkien's legendarium such as Mirkwood, Fangorn and Lothlórien it serves as the central stage in the theatre of its time, the First Age, as described in the tale of Beren and Lúthien from The Lays of Beleriand, parts of The Children of Húrin and The Silmarillion.
