A word I know, six letters it contains, remove one letter and twelve remains. What is it?

I have one eye and sometimes blink, I see the world and can remember what I think, I steal your soul, some people say, But only when you look my way. A moments pause, a breath held tight, Exposure made, now locked in light.

I allowed you to be and even thrive, I'm known by all on Xbox Live

I move your hand but leave no trace, I’m both your prison and your grace. I vanish the moment you’re forced to choose, Yet I’m the very power you fear to lose. Kings can’t command me, gods can’t refill. Name the quiet rebel ruling you still.

I can solve the the most incredulous of crimes. And I’m known to weave the most intricate of patterns. Sometimes I bite, I won’t let go and finally need cutting off.
