This is all because the sage didn't expect Soverick to be so impressive. Salvos was to be the undisputed leader. But Soverick has risen to the task. It is unfortunate that there can not be two tigers on one mountain. The divine crown that the first sage sought to use to strengthen one battle sage monkey will cause conflict between Salvos and Soverick.
The third problem is the progress that Soverick is making in breaking into the core. It is ahead of time, far ahead of time. The sage expected something like this to happen. He didn't foresee the situation exactly but he knew that it could happen. He expected that something will happen to help Soverick and expedite his gaining access to the core. He is the child of the plane after all.
