Poderia o Um Anel ser destruído de qualquer maneira além do Monte Doom?

From splendour he fell through arrogance to contempt for all things save himself, a spirit wasteful and pitiless. Understanding he turned to subtlety in perverting to his own will all that he would use, until he became a liar without shame. He began with the desire of Light, but when he could not possess it for himself alone, he descended through fire and wrath into a great burning, down into Darkness. And darkness he used most in his evil works upon Arda, and filled it with fear for all living things.

E em "Do começo dos dias":

And in the darkness Melkor dwelt, and still often walked abroad, in many shapes of power and fear, and he wielded cold and fire, from the tops of the mountains to the deep furnaces that are beneath them; and whatsoever was cruel or violent or deadly in those days is laid to his charge.

Vulcões são explicitamente associados com Melkor no Silmarillion como as cicatrizes remanescentes no mundo depois que os Valar "consertaram" o dano:

In that time the Valar brought order to the seas and the lands and the mountains, and Yavanna planted at last the seeds that she had long devised. And since, when the fires were subdued or buried beneath the primeval hills, there was need of light, Aulë at the prayer of Yavanna wrought two mighty lamps for the lighting of the Middle-earth which he had built amid the encircling seas.

Eu acho que Sauron, sendo o mais poderoso discípulo de Melkor, teria forjado o Anel nos fogos de Utumno, se ele tivesse a oportunidade:

The lands of the far north were all made desolate in those days; for there Utumno was delved exceeding deep, and its pits were filled with fires and with great hosts of the servants of Melkor.

No entanto, a fortaleza de Melkor foi totalmente destruída após sua queda. Talvez o Monte Doom ainda detivesse a maioria dos resíduos ou ecos do poder ou malevolência de Melkor.

Se qualquer outro vulcão estranho pudesse fazê-lo, Gandalf não precisaria arriscar que o Anel caísse nas mãos de Sauron enviando Frodo para o meio de Mordor

Eu acho que fenômenos da física como o calor são irrelevantes aqui. O Ring deve ser destruído no final da Journey , por uma combinação de Magic e Fate . Não é apenas o calor intenso do Monte Doom que o destrói, mas o fato de Mount Doom ser uma característica importante da Terra Média, de volta de um tempo eterno quando ... etc, etc.

Um terror tecnológico como a Estrela da Morte não pode fazer parte do Anel Único, simplesmente porque a arma não é eterna nem mágica por natureza. [Nota: eu menciono a Estrela da Morte porque é sobre a questão original, antes de ser editada] .

Agora, se alguém usar a Força ...: P

Declaração de apoio de Elrond (do filme, infelizmente):

The Ring cannot be destroyed, Gimli, son of Glóin, by any craft that we here possess. The Ring was made in the fires of Mount Doom. Only there can it be unmade. It must be taken deep into Mordor and cast back into the fiery chasm from whence it came.

Ele nunca diz "... ou qualquer outro fogo de intensidade equivalente".

O Anel pode ser destruído apenas pelos Incêndios da Montanha da Perdição, porque esse é o lugar onde foi feito. Os anéis menores de poder poderiam ser destruídos pelo fogo do dragão, como Gandalf menciona:

"Your small fire, of course, would not melt even ordinary gold. This Ring has already passed through it unscathed, and even unheated. But there is no smith's forge in this Shire that could change it at all. Not even the anvils and furnaces of the Dwarves could do that. It has been said that dragon-fire could melt and consume the Rings of Power, but there is not now any dragon left on earth in which the old fire is hot enough; nor was there ever any dragon, not even Ancalagon the Black, who could have harmed the One Ring, the Ruling Ring, for that was made by Sauron himself.

There is only one way: to find the Cracks of Doom in the depths of Orodruin, the Fire-mountain, and cast the Ring there, if you really wish to destroy it, to put it beyond the grasp of the Enemy forever."
