Teacher: Earth that was could no longer sustain our numbers, we were so many. We found a new solar system, dozens of planets and hundreds of moons. Each one terraformed, a process taking decades, to support human life, to be new Earths. The Central Planets formed the Alliance. Ruled by an interplanetary parliament, the Alliance was a beacon of civilization. The savage outer planets were not so enlightened and refused Alliance control. The war was devastating, but the Alliance's victory over the Independents ensured a safer universe. And now everyone can enjoy the comfort and enlightenment of our civilization.
