Axx is at worlds end, his planet dying. Fortunately he is able to find a distant planet that his people can inhabit; the surface, plagued with infection, is dead anyway, so it mattered not if it burned for his people's safety. The flying cities above would never be harmed, so nothing of consequence could happen. Sadly, this planet, Earth, was not ready to die without a fight, for a small percentage infected with the plague didn't die, but came back stronger.
