SE I am disappoint (Possible Spoilers)

[Ibi]

You're going to give us three statues that look an awful lot like the esper gods of FFVI, yet not have them play any role in the story, or even show up in the lore? Sad Panda I am.

Though they don't appear in the main story, the Extreme primal quests are essentially based around the Triad, and the potential threat they represent.

It's suggested that:

1) they were the real reason that both Thordan VII, along with his Heaven's Ward, and the Garleans went looking for Azys Lla in the first place, and
2) Bismarck and Ravana both have the means, if given the opportunity, to seek out the Triad in Azys Lla as a source of immense power, and that this must be prevented at all costs.

Naturally, this being only the start of the expansion, things are left very open ended, but you can expect them to feature heavily in future patches.

Given a choice, I'd prefer more characters like Matoya or Hilda: recognizable names with recognizable common details, but otherwise proper FF14 characters in their own right.

I think that's exactly what we'll be getting here.
