(Whee, I'm going on a review spree ... or something.)
I really loved this. Kain/Edge wasn't really something I would have thought up before ... but having just in the last few months gotten myself exposed to FFIV, I did immediately take to the Kain/Cecil/Rosa triangle. I have to say I particularly enjoyed the not-as-game-translation dialogue; somehow Palom and Porom speaking like 20th century teenages always threw me off anyway.
... Now I'm going to have to go look into your other IV stuff. >_>;
