Calamities explained

[MrThinker]

If Lahabrea or Elidibus could have taken Tupsimati at any time before the WoL, then why didn't they?

Simple, it wasn't a factor in their plans at the time. Or rather, Elidibus wasn't really active as a force until we beat Lahabrea, so it is actually more "wasn't a factor in Lahabrea's plans".

It's best not to try and divest the plot of every little thing, because it will fall apart.

Actually, doing this is the exact reason the lore forum exists. And then we gather up the questions with the most glaring plotholes and present them to Koji or Oda or even Yoshi-P to try and cover them up.

Also, if shard Ascians could touch down on The Source unassisted, free to sow chaos to their heart's content and bring on the next ardor, then why didn't all 13 members of the Convocation do just that once we'd cast out Lahabrea and ruined their plans the first time? To me a restriction on their coming and going makes the most sense.

The true answer? Arrogance, a staple trait for most Final Fantasy villains (not all ofc). They believed themselves better than us, and payed the price. What I find less believable is that the Ascian Overlords do not have a sense of camaraderie regarding their shared origin. Remember when Nabriales got destroyed? (Lahabrea: Eh, he brought it upon himself). How about with Igeyhorm and Lahabrea (Elidibus: those idiots left a huge mess for me to clean up), and Elidibus in general (Elidibus: I do not mind if you kill the black robed guys if it is part of your plans) (Note:granted this can be retroactively ascribed to being able to bring most of them back through their other shards, with the excption of Lahabrea), but all in all that is most likely due to a change in direction of writing rather than everything else.
