Answer:
A dragon's tooth in a mortal's hand, I kill, I maim, I divide the land.

I am tomorrow's yesterday and yesterday's tomorrow. What am I?
I move without wings Between silken string I leave as you find My substance behind.
I am the book one can never finish reading
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
