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.
Thranduil
Thranduil is a fictional character in J. R. R. Tolkien's Middle-earth legendarium. He is a supporting character in "The Hobbit", where he is referred to as the Elvenking, and he figures briefly in "The Lord of the Rings", "The Silmarillion", and "Unfinished Tales". Tolkien describes Thranduil as having a crown made of red leaves and berries in the autumn, and wearing a similar crown of flowers in the spring. "The Hobbit" describes the woodland king "with a crown of leaves upon his golden hair". Like most of the Sindar, he would have been beardless, tall, and grey-eyed. The name "Thranduil" means "vigorous spring" in Sindarin.
