IF YOU DO NOT WANT TO BE SPOILED< DO NOT READ MY POST!!!Well it's complicated because at the end of the game when everything starts to turn back the creatures just disappear, yet at the start everyone turns into a creature so I suppose Marche was killing off some people or lots because they all disappear and god knows where they went. But the next march and mewt were talking to lyle, colin and guiness who were surley those undeads. So I can't really come to a conclusion but I suppose all the other might have not appeard in st Ivalice might be dead. I also do agree with skyblade for some so i'll save myself some time from typing.
