More Allagan ruins, more Allagan descendants (Sadu, in case you missed her copying from the Royal Allagan Spellbook), and yet another new discovery that makes a certain defanged solar power plant feel, well, completely harmless on the sliding scale.
Currently on the table we have:
- The Binding Coil: AKA Dalamud bits everywhere. Deactivated, destroyed, and sealed by the Scions.
- Syrcus Tower, sanitized and then (suddenly) sealed on (an interpretation of) Salina's orders that it might provide "hope" at some unspecified time in the future.
- Azys Lla, everyone's favorite research facility/gift shop, still just sort of there, even without the Triad. Active and airship-accessible. Even to Garleans.
- Omega. Apparently a more direct instigator of Allag's rise to technological dominance, in addition to killing/sealing Bahamut. And wrapping Shinryu up with a bow on top for Zenos to find.
- Heaven-on-High, a completely useless training ground that was important enough to die for. Also built on Salina (and/or Desh)'s orders, though it hasn't stopped a Calamity yet.
- Za Baan, which we didn't even know had anything to do with them until this patch, because sure, why not? Azys Lla came from here, not Meracydia.
- The House of the Crooked Coin, that other giant Allagan power source that basically nobody knew about until now, because sure, why not? Used to power the launch of both Azys Lla and Dalamud, and possibly the real cause of The Burn.
And the bonus round:
- Boulder Downs, an Allagan Ruin unearthed in the calamity that isn't a part of Dalamud, but hasn't really been brought up by anyone (besides Yoshida), in spite of being right there, with a (badly) sealed entrance and everything, since 2.0.
In a vacuum, free from meta concerns about "required" versus "side" content, something has to tie it all together.
And we
still don't know what happened to Nero's modded scanner. It
could have been what led him to Omega, which would have been a feeble but valid payoff for Unei's last moments, but it's very specifically discarded
before Nero makes his way to Omega and reactivates it. It found something very close to the Tower, and it's just been sitting there beeping for ages. Actually, it's probably out of batteries by now.
