Rath only ever scanned TWELVE newborns. They don't scan new children for each one born in Underworld. Instead, they took the copies of the twelve newborn Fluctlights, erased any differences among them, and created a blank-slate template that could then be copied indefinitely for each new person born in Underworld. The process is entirely automated, seeing as no one's going to be able to do it manually when Underworld is sped up at least 1000x the majority of the time.
