"Deceased" is not to include characters which, while no longer "among the living", are still very much active.
Characters which are "no longer living and breathing" yet somehow *active*, such as Ghosts and other form of Undead, are to be *reassigned* to a New Category: Undead.
Further more, to be considered as Deceased, a character MUST FIRST Be or Have Been Alive, and THEN MUST be seen or mentioned as dying/destroyed. Any lacking the latter will NOT be considered as Deceased, but at best only apparently deceased, and thus stated as such in their Article and left out of Deceased.
This policy will be included in the forthcoming Manual of Style.
