PORTAL: Where Is Here?

"Okay, so it's definitely water," Jeremy said. "But how did it get here?" "Where *is* here?" Sarah asked. "I think that's what we really have to ask. What I wouldn't give for a way to know *that*." Suddenly, they heard something fluttering through the air. They looked up into the red alien sky and saw something white twisting this way and that. And a short time later, it fell to the sandy ground only a few feet from them. Jeremy picked it up and looked at it, seeing that it was a piece of folded up paper. After unfolding it, he looked up and stared at Sarah. "What?" she asked. "Take a look," he said, showing it to her. "I don't believe it." "What?" Lizzy asked. "What is it?" Sarah held it up so they could all see it. "It's a map." It was almost as if what she most wanted at that moment had come true.
