- Venusian Voice: Last Of Man, listen. The craft you are attempting to communicate with no longer exists. Your sister craft no longer exists.The signal you are following is a warning. Had you been able to decipher its meaning, you would not have attempted to trespass on our world.
- Danny: Your world. Who are you?
- Venusian Voice: We are the collective minds of this world your craft now orbits. Be it enough for you to know that during the span of our evolution, our civilization has witnessed the birth and death of worlds and suns untold. But enough. Your time is short. You may not enter our world. We have witnessed the self-destructive powers of the green planet you call Earth. We have no malice toward you. You have destroyed your place in the universe. Last Of Man, listen. Of this we will tell you. Your journey will continue. Something very strange and very great awaits you beyond the rim of the universe. And now, Last Of Man, your journey will begin.
