Which Ascians are left? (Spoilers up to 5.4 obviously)

The only evidence we have now (Fandaniel's speech), however, points to Fandaniel being an omnicidal maniac with no other goals. It's possible there's something deeper - in fact, I will be very disappointed with the writers if there is not - but anything else is pure speculation, with nothing in-game to support anything over anything else.

To be honest, I would probably be at least a little disappointed if Fandaniel's "true goals" (as hinted in the Endwalker reveal showcase) was something deep and meaningful and had absolutely nothing to do with his current declaration of wanting to kill everything and everyone.

Mainly because it would be kind of eye-rollingly exasperating if the reason he did all that was entirely because he had an overblown sense of drama and wanted to troll a reaction.
