i think necron is just one of those "im the REAL bad guy" type scenarios just put in there for token effect and shock factor......just when you think its all over FF has a habit of having the main bad guy coming back from the dead or some other dude just showing up to try to destroy you lol its just there to take the palyer by surprise just like movies do when the hero thinks he's killed the badguy when he hasnt and then the badguy takes his chance and trys to shoot the hero in the back....its purely a suspense and surprise device of directors thats meant to give one last thrill before they lay the game/film to rest......
