nice.
Only real comments I have for this one are... well, first off i didn't understand Kefka very well. I assume what he talks about will make more sense later.
The thought of someone driven more insane then Kefka scares me.
And Mog /Locke got very weak after the few weeks without fighting. falling to simple enemies like those? :p
And something I thought of before.. Kefka has a lot of magic left in a world without magic. one would think when he was defeated, the magic he held would try to return to the statues... which you destroyed, thats why Magic no longer exsists. If he still posses the magic from the statues, everyone should still have thiers.
