The Soulcore

The Soulcore is a science fiction short story. It is mainly intended to delight and entertain; and it is suitable for both youth and adult readers. An extra-terrestrial from the Andromeda galaxy (A distance of 2.2 million light years from our milky way) comes to visit the earth carrying with him “the most precious jewel in the universe.” However, at the gateway into the earth, he is met with arrogance, greed and deception. He is defrauded of the invaluable jewel and virtually expelled. But the hoggish terrestrial fraudster does not know what it is he has taken upon himself for the jewel is in fact not just another precious stone. Simple human error brings him great remorse; and soon Saul is converted to Paul and cast into a crater. From there on, the motif of loss and search get the upper hand.
So who are Mtembezi Ulimwengu and Mwangalizi Thabiti? What does the Soulcore symbolize? What is the crater? What is the human race looking for? Overall, is the Soulcore a story of hope or despair?
