In Book 1 of this series we found out how the invention of the power module by Albert Simpson changed the Earth. It brought on an era of prosperity and scientific development unlike anything the people of Earth experienced before. The inexpensive and unlimited power that the power module provided replaced every previous form of energy. It powered our cars, homes, businesses, trucks, ships, and even airplanes. The money that was previously used to pay for energy was instead used for scientific and medical research. We quickly eliminated most known diseases and began exploring our solar system. After we developed the ability to travel to other solar systems we had our first encounter with aliens. As a result of that meeting Earth became the newest member of an interstellar trade group. Book 2 begins with the exploration of Procolt 2. The atmosphere, temperature, and gravity there were almost identical to Earth. During the exploration of Procolt 2 the first non-humanoid intelligent beings in our part of the galaxy were found. Our involvement with them enabled Earth to become the most prosperous member of the trade group in less than fifteen years.
