What Zeke and his companions do not know is that, a wave of soldiers, the primary ones, have already been deployed in every continent. In short, they arrived a second too late in order to stop Gallio. And this is mainly due to Pier's tampering of the transportation.
He made it so that, Zeke and his allies would come to Elysium a week later. This is possible because, the god of mischief and deceit has a hundred minor gods backing him up. Within this span of time, a lot of things have already occurred. The first is Gallio's deployment of his forces to every other continent.
