Twelve Worlds Centrum was a consortium of twelve gigantic fortified worlds which had been chosen, built and modified over generations of posthumans. Nobody knew if these twelve worlds were geographically and dimensionally close to each other. In fact, there isn't any real alliance between them. In the early days, some of the large worlds didn't even know of each other's existence.
Due to their natural resources and level of development and modifications, they were gradually grouped together and named Twelve Worlds Centrum. Even though this wasn't Lin Sanjiu's first meeting with a resident from the Twelve World Centrum, she was very curious and had many questions. Unfortunately, it was difficult to ask them these questions now.
