So given the trailer
Bozja
More lucavi specifically Adremmelech was shown off, have type-0 enemies and bosses so can probably see more getting pulled from that game in future, story looks like someone is getting possessed (most likely turning into Adremmelech).
Weapon saga
Get in the ava, adventurer. Sorry couldn't help myself, but that is exactly what we are doing so props to the person who called out it was ironworks that made it, also ironworks seem to be progressing technology faster than Garlemald does, i'll chalk it up to Cid.
Yorha
Bunker time, though looks to be mostly original bosses this time with only the androids helping one of them out as adds/aoes. Interested to see where this all goes.
MSQ
So Exarch G'raha is dying but still up in air on the how seeing how we see him get stabbed, exhausted, crystallise all in the same trailer. Ryne headpat of sadness. Looks like we are facing a barbarian as the final boss of the dungeon particularly someone who is a berserker(possibly have aggro issues), I wonder if the bosses are mutated WoL because they big.
So we have pure light people attacking the citizens mayhap an over exposure to Hydelyan forced by the starshower ala Leviathan's drowned from Satasha HM.
