Because every competitor of each power returned to their own elders and leaders after the spatial gates, only the Jamai Sect knew that the twins did not come out. Of course, the Rambram Sect and the other three were included, but they knew how to keep their mouths shut since it was the Rambram Sect that promoted the competition for the Free Continent.
With that said, Folesve called the Jamai Sect over and began an interrogation. Or, to be more specific, he and his Rambram Sect were checking if the twins were within one of the competitor's Pocket Dimensional Realms. After all, the twins' cultivation was two entire realms below the Space Bending Realm's participants. It wouldn't be a problem for them to keep the twins inside.
