Saving Durin {Hobbit/Thorin}

My following words of yore and spite may shock you to the very core. They acknowledge a fact known to few, and even less, known to heart. But please, by the whim of mind and patience of soul, I beseech you to listen all the clear.
Tolkien's tale of Middle Earth has fallen from its original translation. His story of Thorin Oakenshield's company once bore truth, but fate was reconstructed in light of a prophecy:

The girl born of flame,
fostered by the dwarves,
royal in her name,
and her child's birth.

She is the one and only
protector of Middle Earth,
guardian over Mordor,
savior of our royal dwarf.

Her knowledge will be countered
by family's unknown survival,
though fate will turn it right
as in sacrifice of her royal line.

It isn't just a story,
but the Valar's greatest mistake;
let the heavens toll loud
to save Durin's sons

After the war of the ring and the destruction of Sauron, the Valar decided to repeat the past, starting at the union of the company within a small hobbit hole in the typically quiet Shire. Why, you may ask, did they decide to do this? Originally, the Valar had ignored the prophecy stated above (as they had done in the past), allowing the Durin line to be exterminated by the Pale Orc, Azog. However, the reign of Dain and his heirs as they took Erebor's throne turned out to be heartless and cruel, unlike the intended fate of Erebor foretold. Therefore, the Valar decided to turn back the clock, 60 years, giving Gandalf the idea to invite the "girl of fire" to the meeting in Hobbiton. Indeed, this did bring about the intended fate of the Lonely Mountain as well as infinite happiness to the company of heroic dwarves.
This is her story, as she sacrificed her line in saving Durin.
