What's the name of this song?

I only know a few lyrics to the song and I was wondering if someone knew what the title would be?
Okay well its only a chorus and a piano. The intro line is 'Give me peace the sapphire lights flicker.' Then something like 'Hunters and Jackals sing of the fall.' 'Heal their pain, the wounded are crying.' or '... dying.' one of the two.
'Fire burns their hearts, something something skin'
Then it goes 'steel...'
