After the second trial? Wow you missed out. After... I think it's the sixth trial the story really picks up. They pull an Umbrella Corp on the Aether Foundation. I think one of the main flaws with the main series games is pacing. Unlike PMD, they don't thread the storyline in very well. They did better with SuMo by making it not only a right of passage but also by completing all the trials and such you had a shot at helping found the League, which was pretty cool. But I feel like if they could weave it together better like with the PMD games where every dungeon crawl had some sort of purpose, it would make the games a lot better. I'll be candid here when saying the reason I always have the "no grinding" rule on my nuzlocke challenges isn't because I want to make it more difficult, it's because I don't want to grind. It's boring and tedious, whereas with PMD you're out there saving a pokemon, returning a valuable item to them, catching an outlaw. And the main series games could do this too if they implemented side quests. Like, we have them but not near the amount necessary and they don't provide much replay ability.
