Answer:
I am two-faced but bear only one. I have no legs but travel widely. Men spill much blood over me. Kings leave their imprint on me. I have greatest power when given away yet lust for me keeps me locked away.
I drift forever with the current and flows to your everyday life. I make living easy but I am good at killing people too.
Drop me and the world will shatter. You can always find me where you empty your bladder. What am I?
I am whole but incomplete. I have no eyes, yet I see. My largest part is one fourth of what I once was. What am I?
I fly yet I have no wings. I cry yet I have no eyes. Darkness follows me. Lower light I never see.
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
