Yah thats the only thing that doesnt fit with some of the Allagan lore. Allag gets destroyed- think we can guess how now. The naming convention of the 12 makes me think high court. Azemya is literally a warden, Oschon the absentee noble, etc. But what is interesting is for a pantheon of gods- there is no zeus. There isnt a king. The king gone mad with power becomes a force of destruction his vassals seal him allag falls end of an era- rinse repeat~.

The voices in answers make me think they are people of some type, every other FF song had plot details hidden in it.
