In the Great Clone War, most of the technological advancements of the 20th and 21st centuries were wiped out. Slowly, the survivors of the war began to rediscover and rebuild some of these inventions.
There was a child, seven years of age when the clone wars hit, named Orlando Poon, Jr. His father had been killed in the war, but before he died, had laid a burden on his son's shoulders: Clean up the toxic ravines. This was no easy task, but Orlando Poon, Jr. had his father's conscience, and knew that he must somehow achieve this. He set about reinventing engines, balloons, robots, and bombs to achieve his aim.
The toxic ravines were quite a mess. No human could safely enter the ravines, because of various gases and radiation. They were dangerous as well because of various creatures that inhabited them, all the misfortunate stepchildren of failed genetic research. Mixed in with all the toxic waste, there were also nondescript capsules which contained the PANG clones, and Orlando Poon, Jr. was determined that these nice little people should be rescued. He soon discovered that more PANG clones had escaped from their capsules, and were hidden in caves at the bases of the ravines. They could not leave the caves, because of the toxins, and they had sealed the entrances to protect themselves from the denizens of the toxic ravines. These too, Orlando vowed to save.
Orlando built blimps and hired blimp pilots to drop cleanup bombs on the toxins, and to send remote control rescue robots down for the PANG clones. These pilots soon discovered another danger of the ravine -- the toxic wraiths.
These wraiths grew from the very worst of the toxins -- those vile substances that had seeped into the ground beneath the ravine. Any cleanup bomb that accidentally hit the ravine floor would release dozens of these wraiths, who would come up and decay the fabric of the blimps. So only the most skilled of pilots could be hired...
