Sting (Middle-earth)
Sting has the magical ability to detect orcs or goblins nearby, glowing blue in their presence, as it did when the Fellowship encountered orcs in the mines of Moria. Tolkien establishes this as a common property of First Age Elf blades, particularly those forged in Gondolin. Sting is also exceptionally sharp. Bilbo manages to thrust it without effort deep into a wooden beam at Rivendell. Frodo also wounds a troll in Moria, after Boromir notches his own sword with his attempt. Sam uses Sting to cut through the giant spider Shelob's strong webs with ease, and also wound the spider, driving it away from the paralyzed Frodo.
Tauriel
In 1937 J. R. R. Tolkien published the fantasy novel "The Hobbit", whose plot centres on a group consisting of the titular Bilbo Baggins, Gandalf the wizard and thirteen dwarves, who go in search of a treasure guarded by the dragon, Smaug. During the course of their travels, they enter the black forest of Mirkwood, where they find themselves in the dungeons of the Silvan Elves. During the climactic Battle of Five Armies at the end of the story, the dwarves, men and elves band together to fight an army of goblins and Wargs.
Although the character Tauriel does not appear in this story, she was created to be the head of the Elven guard by Peter Jackson and his writing partners Philippa Boyens and Fran Walsh, (who is also Jackson's wife and producing partner) in order to expand the world of the elves of Mirkwood Forest, and to bring another woman to the cast, which is otherwise dominated by men. The character Tauriel is a Silvan Elf, which means she is of a much lower order than the elves that had previously been seen in "The Lord of the Rings" film series, and holds a lower social status than characters like Arwen, Galadriel, Elrond, and Legolas. A Woodland Elf, her name has been translated as "Forest Daughter."
