My Warmth Gone Cold

I saw you there, so fair and true
I knew not what you planned to do
Your eyes went dark, your light had gone
How was I to right your wrongs?
I saw the blood, I could not speak
You held a weapon, and I was weak
That shell of you, it stood before me
And when I spoke it did ignore me
I will not tell you how it ended
For I did things I had not intended
But forgive me if I hold you too closely
Or watch your eyes a little more
For though I know you are not my demon
I'd hate to find it at my door
