I thought both Necron and the crystal came out of nowhere! I was like

"Dude, WTF?"

But then again, if it was Garland, that wouldn't make sense, because he turned semi-good at the end, then again he didn't....

I think maybe Necron was Soulcage in a different form, then again, it could also be the soul of the Iifa Tree itself...

I like Kuja's Trance Theme, his regular theme, pandemonium, Beatrix's Theme...and gosh, just every piece of music is great!
