[quote][Quistis's name is reportedly of French derivation and is pronounced "KEY-stis".]

Like I said, it's a french derivation and most people call it ''Key-stis''
But there's no K in Qu...
And one question, are you french, if so, try saying Squall in french...
( it's a little funny.)
Know what I mean?

The kana for Quistis' name is something like (doesn't remember 100%) Kisutisu, which leads to the 'KEY-stis' pronunciation.

I used to call it 'Qwi-stis' before, but we all used to say 'Yuf-fee'.

Irvine: Er-vine
Edea: Is it Edee-a? That's how I've pronounced it. I'd have to wait and see though.
Kiros: Key-ros
Adel: Ah-dell

The rest I either forgot about or are obvious.
