The Ascians can't make up their minds when it comes to the WoL...(Major Spoilers)

[Devtek]

I think they have a grand plan to release Zodiark but some of them have different views on how to make that happen. Even the Ascian's have an Ego.

There are 13 Black Robe Ascian + Elidibus. We have only met 3 of them though. All 3 of which are now dead.

Loghrif
Mitron
Emet-Selch
Pashtarot
Fandaniel
Altima - Seen in a Cut scene
Halmarut
Nabriales - Dead
Igeyorhm - Dead
Deudalaphon
Emmerololth - Seen in a Cut scene
Lahabrea - Dead

Im not convinced that Elidibus is even an Ascian to begin with.

There are more black robed ones with generic names in the Summoner 50-60 quests. Blah Blah of the 12th Chalice etc. Killed 5 of them in the 60 quest alone (although probably not dead dead). Team Rocket of the bad guys.
