Tell me one think I don't get...
What does Necron has to do in the game.
I've a teory:
Kuja once said something like this: I need a stronger eidolon than Alexander to beat Garland. And he tried to found that eidolon in Eiko, right?
Then, he discovered about Trance. Then in the Invincible he used all the souls in there, right?
So maybe one of those souls could of Necron, right?
