Interesting thought. What do you think would have happened to the Kingdom of Figaro and more importantly, Sabin and Edgar?
I'd figure Sabin would continue his martial arts training and pass it down to the military, kinda like Fabul in FFIV. I doubt they'd be on good terms with the Empire, as Sabin was a lot more vocal about his dislike of them during the flashback scene. Conversely, I picture Edgar just trolling for opera floozies all day in Jidoor and having a house littered with crazy inventions.
What do y'all think?
