Its all very confusing....
Sounds like we need a thread just dedicated to deciphering the lore....

I believe the intention is for Dalamud to fall

In the quest "two vans are better than one," Legatus Gaius Van Baelsar reminds Legatus Nael van Darnus of a past tragedy where they couldn't control where Dalamud landed.... and Darnus responds that he is in possession of Allagan artifacts that will lead him to another artifact that will indeed control where Dalamud will land...
This conversation is VERY important... because they also reference meteor....

You guys can call me stupid for this.... because I can't figure it out.... but I can't tell if the Legati are using "Meteor" and "Dalamud" as interchangeable terms of if they are truly 2 different phenomenon
