Answer:
My life can be measured in hours, I serve by being devoured. Thin, I am quick. Fat, I am slow. Wind is my foe.
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard.
A dragon's tooth in a mortal's hand, I kill, I maim, I divide the land.
Metal or bone I may be, many teeth I have and always bared. Yet my bite harms no one. And ladies delight in my touch.
Someone walked into a room and you heard a crash! Someone died. What happened?
Iām grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
