The number of known previous civilizations that have crumbled to dust, has increased from single to double digits as we discover more of our own history.Some historians believe that external causes, such as conquest, the use of lead by the Roman Empire or the black plague in Europe, drive civilizations to their demise. All seemingly after attaining the apex of technological advancement of their time. These and other externalities may have contributed to the decline of the civilizations which they affected. However, if one accepts such externalities as the reason for the decline of entire civilizations, one must also accept that they are chance, the luck of the draw for that civilization. Then one must wonder if it is just coincidence that such bad luck occurred to every civilization preceding ours.The protagonists in this story discover they are in conflict with a culture that, from unreachable orbiting space ships, has destroyed entire continents by dropping asteroids on them. An enemy whose most powerful weapons are economics and social engineering. To survive, they seek and discover the answers to the age-old questions:What causes civilizations to rise and fall?What tax rate makes a person a slave?
