This was a pretty sweet lore dump for certain monsters, but one of them was an enemy we'd been wondering about since we saw it in the Dungeon trailer. So, after running through the dungeon and encountering a certain construct and reading their data entry...
...I guess we know how the Ixal came to be. They were initialy Allagan creations designed to perform maintenance, and called Ixsalion. They suffered from weakness to the elements, and were prone to genetic degeneration, I think was the word used. That would explain why they lost their wings and can no longer fly, and why they are excellent craftsmen. Most likely they escaped from the Floating Continent when the security systems of Azys Lla began to fail.
So, does this mean that Azys Lla is their fabled Ayatlan? If so...I hope they never get there. Damn Allagans messing around with nature.
