3.2 Sephiroth

[Nalien]

At the very least it would be nice to get more lore outside the game/encounter... Ifrit, Garuda, and Mog were all made far more interesting than they actually are by additional information provided. Ifrit less so, but the story with Garuda and the Lord of Snakes, coupled with Ixalis origin in Azys Lla, and the proximity of Vanu Vanu (who protected the Key to Azys Lla...) who ride snakes... That made the insane harpy more interesting to think about. Likewise, the Mog myth, discovery of Moghome and their relation to Thordan/Nidhogg, all make for a much more interesting story, even if their characterization is none existent/one note.

I have a feeling Sephirot won't have much of a personality other than "kill kill kill!" especially since he's been locked up longer than Bahamut and a Warring triad member

See, that makes me think he should have more personality... He is one of the Warring Triad, a trio that has always just been a plot device, this would be the perfect chance to make them something more.

As for Bahamut, well... He was royally pissed off before the Allag played Space Pokemans with him... Not only was he killed by them, he was summoned back by his beloved who then viewed him as stain on his memory (even if he isn't Bahamut, like Ysayle/Shiva I'd imagine he'd have thought he was the real deal at first). Add to that him and his fighting a losing war, and Dalamud effectively being a torture chamber... Yeah... I don't want to meet the man... dragon... thoughtform... whatever, who is sane after that...

On the other hand, we don't really know what circumstance the Triad fell to Allag... Given their apparent power, one wonders how they were "captured" or why they were put to use on something so menial as creating synthetic crystals... I'd hope for something a bit more true to VI, where the Allag didn't contain the Triad, they found the Triad "sleeping" and set to work harnessing their power without waking them up. It would explain why something like Crystal Tower was required; The Triad might have limitless power, but only a fraction of it was tapped into... Tapping into more would risk waking them up (#ThanksThordan), and then who knows what happens... If they're as strong as they're hyped up to be, one would wonder how we even have a hope of besting them... I would like to think this will be similar to the Ramuh encounter...
