The Twelve was the term given to the first twelve extrasolar human colonies. The Colonization of these twelve worlds was also known The Great Experiment, answering the question: can humans colonize deep space? Eventually, the twelve colonies thrived and the humans began colonizing other planets. The Twelve, Beta Durani and the MacArthur Midrange Colony began to house billiona refugees from Sectors 400 through 600 when the Husnock destroyed their worlds.
