Answer:
What is it something that you always have but you always leave behind?
I cannot be other than what I am, until the man who made me dies. Power and glory will fall to me finally. Only when he last closes his eyes.
I am whole but incomplete. I have no eyes, yet I see. You can see, and see right through me. My largest part is one fourth of what I once was.
You can see nothing else, When you look in my face, I will look you in the eye, And I will never lie.
What is never used unless it's in a tight place?
I will disappear every time you say my name.
