...With that said, it does feel like a ton of this is just not properly addressed ingame and instead handwaved away, like most plot points in the expansion.
That makes a lot of sense and I appreciate the clarification since the story tends to leave a lot of gaps in places that can only be understood retroactively.

My one concern is that...the 12th shard was the calamity of lightning and thus was absorbed through the 2nd umbral calamity. As for how the timing works on that...your guess is as good as mine (unless I'm misunderstanding the lore here which you should feel free to correct me if I'm misunderstanding).
