[Spoilers] Why Zenos is the most important character moving forward

[Iscah]

He's announcing that he's derailed the story for his own selfish desires. Sure, it's related to the story because he's derailing it, but like I said his goals are unrelated to the main story. By assuming the role of main antagonist, he's made it all about himself. But FFXIV wasn't setup to be the Zenos Show all along.

You can't really say that though. He's derailing where we thought the plot was going, but that's doesn't make it unrelated to the story. He's part of the story, and his actions are influencing the direction of it.
