Vecna is depicted in 3rd and 4th edition D&D as the god of secrets. Is there a information (ideally in official sources, but failing that in well detailed unofficial sources) that outlines Vecna's relationship with Prophecy?
Does Vecna's secretive nature abhor prophecy as a method of unveiling truth?
Does the riddle and potential misunderstanding inherent in prophecy appeal to Vecna as a form of comedy, or even as a method of separating the worthy from the unworthy?
Is prophecy something to which Vecna is indifferent?
Or something else entirely?
