a magical ability to decapitate those against whom it is wielded. In the works of J. R. R. Tolkien such as The Lord of the Rings, many magical swords, usually with powers for good, are wielded by important characters. Gandalf uses his sword Glamdring in his battle with the Balrog, which wields its own sword of flame. Glamdring's sister blade, Orcrist, is buried with Thorin Oakenshield under the Lonely Mountain in The Hobbit. Bilbo, Frodo and Samwise carry the sword Sting. It and Glamdring both glow blue when orcs are near. Aragorn bears the sword Andúril, a potent weapon against the evil of Mordor and a symbol of his right to rule. Turin Turambar, the main character of The Children of H%C3%BArin, wields the sword Gurthang. He eventually kills himself using the sword, which speaks to him before he dies, telling him it will kill him. This story is based on the Finnish hero Kullervo, whose sword also agreed to kill him. In addition, in Farmer Giles of Ham, the protagonist is given and wields a magic sword named Caudimordax which, in the story, is translated to mean "Tailbiter". Hal Foster's Prince Valiant wields the Singing Sword, which makes its bearer undefeatable if he fights for a good cause. In Margaret Weis and Tracy Hickman's Darksword series the Darksword is a sword capable of absorbing magic. Michael Moorcock created a sinister magic sword in Stormbringer, wielded by Elric of Melniboné. This black sword has the power to suck out the souls of its victims and transfer their energy to its holder. It also appears to have a mind of its own, sometimes striking against its "master's" will. Mercedes Lackey's creation, the sword Need is similarly independent, although along less sinister lines. The Twelve Swords of Power are the primary plot device in Fred Saberhagen's Books of the Swords. Lawrence Watt-Evans's The Misenchanted Sword (1985) involves the difficulties of dealing with the sword of the title; the protagonist must kill a man when he draws it, can only kill one, will die if he ever kills a hundred men with it – and will not die without killing them, but will ceaselessly age. The Blue Sword contains a blue sword, known as Gonturan, that is both a symbol of power (as it can only be used by a damalur-sol, a woman hero), an amplifier of magic and a very sharp sword.
