The Arkies were just kids, and they had surprisingly little exposure to the GPop. The arklets they lived in couldn’t really change their positions in the swarm. Moving from one arklet to the next was nearly impossible—it was an epic journey in a space suit, requiring some fancy tricks with orbital mechanics. Small utility spacecraft, called Flivvers, were available to squire people around, but there were only so many of them, and qualified pilots were few. Markus, following suggestions from Luisa, had tried to make up for this by "stirring the pot," meaning that about 10 percent of the Arkies at any given time were living and working aboard Izzy. But most of the time, most of them were stranded in individual arks or on triads or heptads, their only connection to the General Population being through videoconferencing ("Scape"), social media ("Spacebook"), and other tech that had been transplanted from the earthbound world. Moira would be astonished if some girls weren’t pregnant already, but no one had approached her about getting an embryo frozen.
