I am needed for most animals and hardcover books. What am I?
One pace to the north. Two paces to the east. Two paces to the south. Two paces to the west. One pace to the north.
I cannot be other than what I am until the man who made me dies. Power and will fall to me only when he las closes his eyes.
It’s in your hand though you can not feel it. Only you and time can reveal it.
