>>46795801You go up a mountain with your father, sister and your dad's co-worker to investigate mysterious slabs you and your sister are able to open. You wind up unlocking the way into the Shrine for Team Tundra. Their home island got buried under fucking ice when a disaster hit the region in the ancient past and the guardians, Latios and Latias, didn't protect it with the rest of the region.
They beat you up, steal the Soul Jars, AKA the Not-Elemental Stars from golden sun, and run off. You and your sister go after them and to find these like... Okay so there aren't Gyms in the game, but their are people in charge of area's who are basically ordained keepers. So battling them is more earning their trust (there's only one so far.) You do two dungeons, the villains succeed, which causes the town to start withering and dying and ghost pokemon and blight to start appearing. And that's where it ends.
So in short, you're chasing down the villains who want to restore their frozen homeland by going to not-lighthouses to not-awaken the power of Alchemy.
It's LITERALLY Golden Sun.
