You know what I would have done with this plot which had prudential, it might sound too much like the Zanpaktu rebellion arc in Bleach, but here goes.

A wizard who loves celestial spirits so much, that he wants to free them from human "slavery", so he uses his magic to brainwash and manipulate the Zodiacs to follow him, citing Celestial wizards are mostly selfish cruel vile creatures and treat celestial wizards like slaves. Which he actual has a good point, consider most of the celestial wizards we meet (Duke Everlue, Karen, Angel, that guy in Grimore Heart whose name I forget) don't treat their spirits like friends like Lucy does.

Turns out this celestial spirit loving wizard is a celestial spirit himself who like Loke did at the beginning of the series was able to live like a human for years, he had a cruel master who died because he got such a big ego and died because of that. In the end, he dies.
