Dragon Hero. Song

Уважаемые носители английского языка, перевожу сам. Подскажите, аутентично ли? Спасибо.


When you fight a dragon for so long,
Everything goes by the law, by the canon.
You drop your faithful sword with a groan —
You've killed the dragon, and you become the dragon.

And you're indifferent to gold, as you once were, it's said,
But you shed your armor, which was dented in the fight,
Now your eyes are yellow, they used to be blue,
Not a mouth, but a slobbering maw, with claws of golden light.

Chorus:
Hero after hero comes to die,
And now for you there is no hell or sky,
You're doomed to loneliness upon your gold,
Until a hero-dragon comes again, behold...

Now a cave upon a high mountain is your home,
Now you laugh at the law and at the canon,
Now the fire burns not from your heart, but from your throat.
Now until death, you are a slave to death, and power's gloat.

And memory presses down, like a joint that aches.
And the laws and canons crawl back, making mistakes.
But then the dragon's head was severed, one clean blow,
It seemed the canon had you cleared, or so...

Chorus:
Hero after hero comes to die,
And now for you there is no hell or sky,
You're doomed to loneliness upon your gold,
Until a hero-dragon comes again, behold...

Again, a hero cries out by a cave on a peak,
He's called the dreaded serpent for an equal fight to seek.
So tired of being a dragon, yet he lived, through endless nights...
And laid his head beneath the hero's strike.

Chorus:
Hero after hero comes to die,
And now for you there is no hell or sky,
You're doomed to loneliness upon your gold,
Until a hero-dragon comes again, behold...
