My problem with the Astral Body thing for Zeira is her appearance, Mavis has an appearance which she had when she was alive, regardless of her appearance when she died. Zeira, on the other hand, if she died in the war, ... well, she shouldn't have that appearance. Unless Astral Bodies can take any appearance that they want ... in which case Mavis has no need to worry about the curvaceousness department. XD That's why I think that it's far more likely that she's an imaginary friend.
