In a faraway land, a middle-aged man walked with two youngsters through the heart of a vast desert.
All three beings had lizard-like tails coming from their backs, covered with sharp spikes.
If one were to ignore the tails, the two youngsters would appear no different from ordinary humans, except for their double pupils in each eye.
The middle-aged man, however, looked nothing like a human. He had a human head, but the rest of his body was mechanical, made from an unknown metal.
It was as if a human had donned robotic armor. For this man, it was his entire existence.
"Soul!" one of the youngsters exclaimed.
"What do you think?" the middle-aged man asked, turning to the other youngster, waiting for his response.
"If it's just the soul without the memories, then will that still be the same person? Aren't the memories we experience what make us who we are? I think it's the memories," the other youngster replied.
