Re: Arcadion Black Cat

If we go with FF9 vibes, the only thing I can speculate from the words "Black cat" related are the Gimmie Cat (with a weird gimmick to get a lotta gil; kinda like Metal Slime giving XP from DQ), or, alternatively, the Black Waltz characters.

Re: S9
My vote is the Enigmatic Maiden is the AI/MCP for S9. Or a surviving Allagan.


Wild Speculation Time:

S9 is the City of Gold that was sealed off. It's been in a time/Stasis bubble. The people are surviving Allagans, or their descendants.

Alternatively, something something Kairos.
