Things that jumped out at me...

The Garleans have a really, really bad navy. And apparently it's just because they aren't interested in sea travel. No wonder the Limsan pirates raid them. And that's good news for everyone in Aldenard who wants to get to Othard and Hingashi. All they have to do is not go too near the Ilsabard coast...

Zenos is Varis' oldest son. How many other kids does Varis have? Will we meet any of them?
It makes a lot more sense now why Varis wasn't initially that annoyed with Zenos dying. I can see him having someone else in mind for the title of Crown Prince(ss) now who would be more suited for the role. And then Elidibus ruins that by inhabiting Zenos' body... There's a lot of potential in that fact.

Aulus mal Asina is mentioned as dying at Ala Mhigo.

Red Mage's sword techniques being related early Coerthen sword techniques is cool. So is the fact that their rapier design was originally from Coerthas.

Love, love, love the page on lore behind the specific polearms. Getting to read the other weapon's pages is going to be so much fun.

Finally! We have a post-1.0 lore source for the Garlean definition of what a beast tribe is! And yes, it does revolve around if a people group have summoned primals or not. To bad we had to wait until the Namazu page to get it...
