I've been watching some of the live letter over the past few days (didn't catch it at the original broadcast time, and I haven't had much time since), and I noticed something at about 3:01:30 -- there's a journal that seems to be relating the story of what happens in the Sil'dih Subterrane. The top lists 'Total 1/12,' which suggests to me that there are twelve different stories we can experience there, and the one on display is called 'A Father's Dearest Wish.' My Japanese is rusty enough that I'm only slowly working my way through it, but it seems that after a battle with some Sil'dih zombies, you come across a group of Amalj'aa from Zahar'ak making a base. I'll keep working on it when I have time, but if someone who's better with Japanese wants to look over it, there's probably a decent amount of info there.

A couple of things from freeze-framing the trailer: at 2:15, we see what looks for all the world like Ferdiad, along with a headless horseman-type enemy and the WoL and a lance-wielding Varshahn. Just from the way they're positioned, I suspect that this is a trash pull in Troia. Which brings up the question -- are we fighting the real Ferdiad yet again (as a trash mob, no less), or is this the first case of his model being reused? (I believe Forgiven Rebellion uses his skeleton, but I don't think anything else has used his model at all.)

Also, there's some evidence that suggests Scarmiglione might be both a dungeon boss and the trial, as has been suggested. At 1:09, we see him fighting with the WoL, Y'shtola, and lancer Varshahn. A second later, though, there's a shot with the WoL, Y'shtola, Estinien, and Varshahn again, this time wielding a sword and shield. Also, the unnamed Reaper is leaping around the arena defeating succubi to eliminate their AoEs. The Reaper could just be a mechanic for the fight, like Brayflox at the second boss in the Longstop, since her motions don't match up to anything a player Reaper can do, but having two sword-and-shield characters in the same fight is unusual, at least. Though on the other hand, the arena doesn't look like it's got enough space for there to be three or four more fighters behind the camera. And elsewhere in the trailer, we see Paladin WoL and Haurchefaunt in the Vault. So it's not impossible that they're using alternate roles for the characters (though I struggle to think of why they'd give Varshahn a sword and shield to be a healer), or just dummying in the WoL as a healer to give split-second shots of the characters they wanted. (Also, at 1:16 we see another bit of the fight(s), and this time it's WoL, sword-and-shield Varshahn, Estinien, and the Reaper, this time all just attacking.) Either way, there's definitely something curious about the party compositions we're seeing, and I'm looking forward to seeing if it's implying something, or just trailer weirdness.
