Answer:
I am the hole in the night, the ever watchful eye. I return in a cycle, to enlighten the sky.
Iron roof, glass walls, burns and burns and never falls.
You will find me with four legs, but no hair. People ride me for hours, but I don't go anywhere without needing to be tugged. Jerked or turned on, I always manage to be ready for work.
The higher I climb, the hotter I engage. I cannot escape from my crystal cage.
