Europe IV

Europe IV is a space city in the Bunker World. Sported a typical football-shaped design, its distinguishing characteristic was the lack of a common artificial sun. Every district had its own miniature fusion sun, and the tiny suns hovered about two hundred to three hundred meters high to provide illumination. The advantage of this approach was that the weightless axis could be more efficiently utilized.

The axis of Europe IV was taken up by the longest—or tallest—building among all the space cities. It was forty kilometers long and connected the north and south poles of the football. Since the interior of the building was weightless, it was mainly used as a spaceport and commercial entertainment district. Europe IV had the smallest population of all the cities, only 4.5 million. It was also the wealthiest city of the Bunker World. Cheng Xin visited this space city in the Death's End.
