Answer:
I am an activity involving pins flying in the air.
I roam through the lands hoping to rescue my love. I search high and low and will stomp on you if you get in my way!
I am longer than a decade and shorter than a millennium
So cold damp and dark I am. To stay you would refrain yet those who occupy me do never complain.
I run up and down the stairs without moving. What am I?
What is always coming but never arrives?
