EXPOSED! The Weight Shall Be Used! But against who, exactly?

LYRICS:
I feel exposed it like I'm rockin the emporer's newest attire
Weight of the world is crashing down on my neck and I can't breathe
I feel so cold but must not sleep, I don't intend to die here
Repeat
Do not sleep
Do not sleep
Let your eyes bleed
Just don't fall asleep

I'm losing all but my hope
Just like Sisyphus pushing stone
I must hang on the nightmare's almost over
War after war I'll keep on marching on
Like Horatius I'll stand against the odds
And face the hoards of Pons Siblicius

I feel exposed it like I'm rockin the emporer's newest attire
Weight of the world is crashing down on my neck and I can't breathe
I feel so cold but must not sleep, I don't intend to die here
Repeat
Do not sleep
Do not sleep
Let your eyes bleed
Just don't fall asleep

They say you're not so dead
When your name echoes through the lands
Don't care if I transcend
I just wanna see this till the end

I feel exposed it like I'm rockin the emporer's newest attire
Weight of the world is crashing down on my neck and I can't breathe
I feel so cold but must not sleep, I don't intend to die here
Repeat
Do not sleep
Do not sleep
Let your eyes bleed
Just don't fall asleep
