A disembodied voice that guides the Blanks in Palamecia. No one has ever seen the owner of this mysterious voice, and only Blanks seem to be able to hear him. Vox has complete confidence in his own words, fashioning himself as a godlike entity, though sometimes he shows intolerance toward those who defy him, branding them 'heretics.'
