What building has the most stories?
Without a bridle or a saddle across a thing I ride a-straddle. And those I ride by help of me though almost blind are made to see.
I rise and fall no matter what, only at finals rest do I not budge. What am I?
A dragon's tooth in a mortal's hand, I kill, I maim, I divide the land.
I can generate fear and some say I come out of your ears. I am as quiet as a mouse but not welcomed in the house. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
