An alien ship drifts silently toward Earth. Inside, two figures lie in hibernation, their bodies still but their minds alive, linked by telepathic exchange.
One is the captain — a being who can sense and process the endless streams of electromagnetic waves around every celestial body they pass. The other is his son, still learning, still stretching his mind under his father’s guidance.
As Earth comes into view, the son asks:
"Father, what is it the people of this planet yearn for so deeply?"
"Love."
"And the other things they chase?"
"Shadows and dust, my son."
