I never realized how manipulated both Isaac's and Saturos' groups were in GS1. I mean Isaac is essentially manipulated throughout the first game and half of the second game because the Wise One tricked everyone into thinking that Weyard would be destroyed if the four lighthouses were lit. The Wise One can't interfere with the actions of mortals, so despite foreseeing Alex's plan he couldn't directly do anything, and he decided to lie to the citizens of Vale instead saying that the lighthouses couldn't be lit at all costs or else Weyard would perish.
What's strange is that the Wise One would rather see the world actually perish (manipulating Isaac and co to risk their lives in order to let the world die) than see Alex become a God. It's kind of silly when you think about it, but since the Wise One is a God too, maybe he thought Alex would be a threat to his God status? Makes me think that if we get a final game, this story could really turn into something waaaaaaay bigger than it's been for the past 3 games, focusing on this issue. When you really look at the character's and their motivations, it's very clear that it's Alex vs the Wise One and that every other character is simply a pawn in their game.
Also this is mentioned in the Wise One's trivia section on the Golden Sun wiki (relating to Dark Dawn):
- It is possible to talk to Isaac after you set out with Tyrell from the Lookout Cabin; although Isaac is out of range, it is possible to talk to him by walking right up to his ledge. After talking to him a second time in this fashion, Isaac will comment that he believes someone is targetting the Wise One with an absolute hatred; after the epilogue of The Lost Age, that is likely to be Alex.
Very cool. I hope if we get a final game they explore this. I have no doubt that Alex is responsible for the psynergy vortexes that appear throughout Dark Dawn, and it could be his way of retaliating against the Wise One. This also means that Isaac has to play an important role in this story since he has some of the power Alex needed to become a God. So my guess is the vortex appears at the end of Dark Dawn to capture Isaac, Garet and Ivan's kid and force Isaac to fight. Mia and Amiti are also heavily tied to Alex and have to return.
If Alex is a partial God he could have the same issue as the Wise One in which he can't interfere in the actions of mortals (which is why he needed Blados and Chalis in Dark Dawn to do his bidding, unlike in GS 1&2 where he needed the Proxians in order to access the Mars Lighthouse)
