When the disaster rocked Utopia, it led to countless victims and the death of all plant life. But the desert was soon filled with new forms of life such as gigantic spiders, enormous carnivorous worms, and bombers with bellies full of explosive liquid. They were all spawned and controlled by a single entity, the mighty Xi, which hides deep within the planet.
Among the hordes of this army of hostile creatures are people who have almost lost their human appearance. They worship Xi as a god. According to their faith, the disaster freed Xi from the shackles of its lengthy imprisonment. Xi will soon regain its power and transform the universe. The old world will be destroyed, and there will be a Great Convergence of all things in the new world. The Great Convergence can be made to come as soon as possible by exterminating all of Xi's enemies, which is what his faithful followers are doing.
