From what I understand Elidibus and Emet were the last two Ascians that were used/part of he project to make Zodiark the first time to save their sun. Fandaniel while an Ascian yes isnt he still a sundered soul thus making him weaker. I just wanna punch his face in for he took the one body of the one character I hated in all of the game. Cant wait to cast his body to the flames and hopefully never see that face again.
I doubt we will not see anymore after this. Remember their souls go back to the 13th world. Unless we trap their souls on our shard they will keep coming back. Elidibus and Emet only got killed by being gut punched by enough light to shatter what fragments of them were left. Emet from the amount of light either in us and Elidibus from the endless power of the Crystal tower. And Laha was for we trapped his soul in White Auracite and had to shatter it with the eye of Nidhogg. They dont die easy at all. We can send them back easy enough but killing them out right has been a major pain.
