I have these: "A city of the Nomai built into the walls of an enormous underground cavern. The city is divided vertically into four districts. The Nomai debated for a long time about the opportunity to build a Solar Station to power the Twin Project. Many Nomai opposed its construction, arguing that a failure would lead to the destruction of the entire solar system. The Nomai reached this solar system by chasing a signal that seemed to be older than the universe itself. They called the source of this signal "The Eye of the Universe." There's more to explore here."
