Battlestar Galactica is set in a distant star system, where a civilization of humans live on a group of planets known as the Twelve Colonies. In the past, the Colonies had been at war with a cybernetic race of their own creation, known as the Cylons. With the unwitting help of a human scientist named Gaius Baltar, the Cylons launch a sudden sneak attack on the Colonies, laying waste to the planets and devastating their populations. Out of a population numbering in the billions, only approximately 50,000 humans survive, most of whom were aboard civilian ships that avoided destruction. Of all the Colonial Fleet, the eponymous Battlestar Galactica appears to be the only military capital ship that survived the attack. Under the leadership of Colonial Fleet officer Commander William "Bill" Adama and President Laura Roslin, the Galactica and its crew take up the task of leading the small fugitive fleet of survivors into space in search of a fabled refuge known as Earth.
Aquarions are highly educated, liberal, tolerant, and peaceful, and think nothing of paying for services rendered with a painting, a song, or a good story, and will accept such payment just as casually. The society is small enough for individuals to remain fully accountable, so the system usually works very well. The colony was founded as a utopian outpost for those who prefer not to be bothered with gods, planetary identity, politics, or other sources of division. As a result, they have developed a strong self-perception as a place where the human spirit and its creative expression can reach their maximum potential. Anyone who disrupts the social balance will find themselves permanently banished to another colony with a simple two-thirds vote, usually finding themselves on Scorpia, or on trial on Libran, never to come back.
