As the judge of souls, Pharasma is intrinsically opposed to the existence of the Final Blades. Pharasmins have made several attempts to destroy Final Blades. While it isn't known if destroying a Final Blade will release the souls or destroy them, it would certain prevent more from being captured. In light of this campaign of destruction against a symbol of the Revolution, Pharasma is banned with almost as much prejudice as Asmodeus.
