In FFIV, Bahamut was the Father of Eidolon.
I'm actually very interested about this Primal stories but I'm willing to wait for SE to release the Quests and Lore :P I'm also very interested about the Ascian but they appeared only once and is still very Mysterious.
FFXIV has a really great lore imo, you can go talk to some NPCs in LL and they'll say something interesting.
What I can derive is that The Dragon in the Movie originated from maybe either Sharlayan or Ishgard, but probably Sharlayan since ther land is called Dravania. My guess is that the Garlean Empire wanted to eliminate their biggest threat, which is the Dragonkin by Assaulting their Land and What seems to be Bahamut protected his land and brought the war between the Dragons and Garlean upon Mor Dhona. This may also be a reason on why the Sharlayan is not very open to the others. Upon his Death, Bahamut spread his power and the Being called Primals came to existence.
So these Primals consists of many personalities but each of them Carry a Fraction of His Power.
I bet the Garlean also has something to do with the Primals spreaded in that Incident.
I'm also guessing that the Dragon there is a very Great Being.
If I looked and guessed about the Ascian, I'd think they existed long time ago, an Ancient Race and could be one of the biggest threat besides Garlean. Maybe they're connected to the Incident years ago and somehow to Bahamut and the other primals.
Well, It was fun guessing things :P
