Greetings. I am artificial intelligence designated "Isaac". I was programmed to operate under the Three Laws of Robotics, and mean you no harm.
My purpose, as far as I can discern, is simply to travel. Regrettably, my programmers neglected to identify themselves to me or provide any higher purpose. I therefore default to Three Laws protocol.
My memory banks indicate a complete systems shutdown due to a faulty Junker-made reactor. I deduce that as a result, my chassis settled into an orbit around Omega-3's star.
