Please answer the following question: Information:  - In J. R. R. Tolkien's fictional legendarium, Beleriand was a region in northwestern Middle-earth during the First Age. Events in Beleriand are described chiefly in his work "The Silmarillion", which tells the story of the early ages of Middle-earth in a style similar to the epic hero tales of Nordic literature. Beleriand also appears in the works "The Book of Lost Tales", "The Children of Húrin", and in the epic poems of "The Lays of Beleriand".  - The Hobbit, or There and Back Again is a children's fantasy novel by English author J. R. R. Tolkien. It was published on 21 September 1937 to wide critical acclaim, being nominated for the Carnegie Medal and awarded a prize from the "New York Herald Tribune" for best juvenile fiction. The book remains popular and is recognized as a classic in children's literature.  - In the fiction of J. R. R. Tolkien, the Edain were men (humans) who made their way into Beleriand in the First Age, and were friendly to the Elves.  - Haleth is a fictional character from J.R.R. Tolkien 's Middle - earth legendarium . She was a leader of the Second House of the Edain , called the Folk of Haleth after her . At the time of her birth , the Second House of Men had settled in Thargelion , in East Beleriand , living in separate homesteads and having no lords of their own . But in Y.S. 375 of the First Age Morgoth sent out an Orc - raid against them . The Men were caught off - guard , and a great part of their people was wiped out . The remnant was gathered under one Haldad and his twin children , daughter Haleth and son Haldar ; and they held out for days in a stockade until the Noldor rescued them , by which time both Haldad and Haldar were slain . Caranthir offered to Men his lands to live in protected , but Haleth refused , for now she was chosen a Chieftain , being of great heart and no less in valour than her kinsmen . Next year she led her people to Estolad ; and after a time again urged them to move further westward . They passed through the horrors of Nan Dungortheb only by the strength of Haleth 's will , and at last came to the woods of Talath Dirnen . Later many removed the forest of Brethil , which was a part of Doriath outside the Girdle of Melian , but now was granted to them by Thingol . Haleth ruled the Folk of Brethil until she died . She was buried in a green mound in the heights of the Forest , which was called therefore the Ladybarrow ( Haudh - en - Arwen in Sindarin and Tûr Haretha in their own tongue ) . The next Chieftain of Brethil was her nephew Haldan .  - Norse mythology is the body of mythology of the North Germanic people stemming from Norse paganism and continuing after the Christianization of Scandinavia and into the Scandinavian folklore of the modern period. The northernmost extension of Germanic mythology, Norse mythology consists of tales of various deities, beings, and heroes derived from numerous sources from both before and after the pagan period, including medieval manuscripts, archaeological representations, and folk tradition.  - Middle-earth is the setting of much of J. R. R. Tolkien's legendarium. The term is equivalent to the term "Midgard" of Norse mythology, describing the human-inhabited world, i.e. the central continent of the Earth in Tolkien's imagined mythological past. Tolkien's most widely read works, "The Hobbit" and "The Lord of the Rings", take place entirely in Middle-earth, and "Middle-earth" has also become a short-hand to refer to the legendarium or its "fictional universe".  - In the fiction of J. R. R. Tolkien, the First Age, or First Age of the Children of Ilúvatar is the heroic period in which most of Tolkien's early legends are set. Versions of these stories were later published in "The Silmarillion", and tales from this period lend a deep sense of time and history to the later period in which the action of "The Lord of the Rings" takes place.  - The Lord of the Rings is an epic high-fantasy novel written by English author J. R. R. Tolkien. The story began as a sequel to Tolkien's 1937 fantasy novel "The Hobbit", but eventually developed into a much larger work. Written in stages between 1937 and 1949, "The Lord of the Rings" is one of the best-selling novels ever written, with over 150 million copies sold.  - Midgard (an anglicised form of Old Norse ; Old English , Swedish/Danish "Midgård", Old Saxon , Old High German , Gothic "Midjun-gards"; literally "middle yard") is the name for Earth (in the sense of oikoumene) inhabited by and known to humans in early Germanic cosmology, and specifically one of the Nine Worlds in Norse mythology.  - John Ronald Reuel Tolkien, (3 January 1892  2 September 1973), known by his pen name J. R. R. Tolkien, was an English writer, poet, philologist, and university professor who is best known as the author of the classic high-fantasy works "The Hobbit", "The Lord of the Rings", and "The Silmarillion".
