There's a space in the darkness, where a fire still burns.
It's beyond a reason, past point of no return.
There's a hunger that's calling, and the fever runs wild.
It's where the light throws shadows on the thoughts of every child

Deep within this hallowed chamber where two worlds collide.
If you open up the door, don't cross the line.

You know it's tearing me apart,
this is the dark side of my heart.
And I knew it from the start,
there in the dark side of my heart.

Just a slave to the shadows, just a pawn in the game.
Drawn to the slaughter like a moth before a flame.
It's the good and the evil, walking side by side.
You can feel it coming, but there is no place to hide.

Tell me all your darkest secrets and I'll tell you mine.
Open up the door but don't cross the line.

You know it's tearing me apart,
this is the dark side of my heart.
And I knew it from the start,
here in the dark side of my heart.

There's an ager on my shoulder,
but the devils whisper in my ear.
It's the battle old as time itself,
a taunt that never disappears.

Tell me all your darkest secrets and I'll tell you mine.
Open up the door but don't cross the line.

You know it's tearing me apart,
this is the dark side of my heart.
And I knew it from the start,
there in the dark side of my heart.
