What am I?

I am a lone wolf, or should you say traveller
Drifting from place to place
Every now and then I get a kick and a prod
Some call me a waste of space

I have many brothers and sisters
A key to a forgotten land
But just to let you know
I am bigger than a grain of sand

And as time goes by
I wonder, what am I?
