What is The Eye doing?

[Morningstar1337]

WoL... just for the sake of power(?).

While that is a possibility, the WoL's motivations are a cipher due to the blank slate thing. With that said, it is more likely that he would desire the power to aid in his Primal slaying (The only one he actually faced by the point Jobs are unlocked was Ifrit) or to protect those that are dear to him, the world, or some other stereotypically heroic thing
