“There are none now alive who know the truth of when or by whom this elder primal was first summoned into the world. ”
I think that a character of such importance to be called elder, should have his own trial or a dungeon with quests centered around him.

I experienced a few small Gridanian quests centered around his release from whatever imprisoned him in the shroud, however for a legendary friend and foe alike that has been central in the universe of many Final Fantasy games, and even featured as a major part of A Realm Reborn's opening cinema, a huge FATE bustling with effects that you can barely see Odin is no place for such a character.
