Why raise him? I don't mean to step on Death's toes, but people do die for a reason, it is not for the Gods to interfere with this process.
not that I would mind, I like Vivi, but him being dead works out better for me. Perhaps if the right people knew of this ceremony...
And what if he does not wish to return? You would merely be forcing him back into a life he does not desire. He certainly won't be the Vivi you remember, death has a habit of changing people.
Do we know perchance how it was that he died?
(ooc: of course the God of Chaos wouldn't want him brought back, with the number of things his life has an impact on, Vivi being dead is certain to cause a good deal of Chaos, powerful beings who cared for him, overcome with emotion, unable to maintain balance, and all that jazz)
