Answer:
I'm a ruler with 12 agents. Half of them work in the darkness. Who am I?
I come in different colors and shapes. Some parts of me are curvy some are straight. You can put me anywhere you like but there is only one right place for me.
I say everything I hear to others around. Iām not an animal nor part of the human race. I will immediately repeat after you; But only if my tail is in place.
Glittering points that downward thrust. Sparkling spears that never rust. What am I?
I ask no questions but receive a lot of answers
I'm the source of all emotion but I'm caged in a white prison.
