Two days before the news that the North had known the Dusty Island's location spread there, there had been thorough preparations in Amerta.
Eros Wang, the Second Guardian Commander, has now been appointed the First Guardian Commander and Warlord. In this critical time, the Guardian system has been strengthened and tightened. All citizens of Amerta, Primary and Secondary, are prohibited from traveling abroad indefinitely. This policy certainly made a lot of Primary People complain. Still, for the Secondary, they felt there was not much change.
Jared Park is the one who sent Eros to his son's place. Even at the first Jared was so worried about Cakara until he felt like he might pass out, but he finally made his own decision. After he heard that Cakara and several other Secondaries were taken to the South with their own willingness, he won't be easy on Cakara anymore.
