Tauriel
Although Tauriel does not appear in this story, she was created by Peter Jackson and his wife and producing partner Fran Walsh for the movie. They did this in order to expand the world of the elves of Mirkwood Forest, and to bring another female to the cast, since it is mostly males. The character is a Silvan Elf, which means she is of a much lower place in Elf society than the elves that had been seen in The Lord of the Rings film series, like Arwen, Galadriel, Elrond, and Legolas. A Woodland Elf, her name has been translated as "Daughter of Mirkwood".
