Suddenly, following a noise of gears and locks, the door started to open, giving way to a dark corridor with pipes and things that looked like cables with a light at the end.
Dan and RAY started to head up the corridor aided by the light emitted by the robot.
The light was coming from some large rooms that were bustling with activity. At the end of the corridor, they entered a factory were some robots were being built. He could also see different doors that led to what seemed to be other rooms.
