So, I've been thinking - and replaying FFIX - and I'm starting to draw some parallels between Kuja and Fandaniel. Obviously things won't play out in exactly the same way but...

- Both of them have a strong focus on the concept of dying.
- Both of them want everybody else to die.
- Both of them are 'incomplete' and lash out at their respective 'Master'. In Kuja's case, it's Garland. In Fandaniel's case it's the Unsundered Ascians.
- Both of them are very theatrical in terms of their mannerisms.
- Both of them have a dragon as a companion/pet.

So, I'm tentatively speculating that we may see 6.0 involve heavy IX themes and inspiration. The game had a very whimsical fantasy style to it not unlike what we see of Sharlayan, too.
