Ya know, this dialogue makes me wonder if there’s a belief in an afterlife in Ivalice. Do the other Ivalice games talk about such a thing?
Vagrant Story’s supplementary materials briefly mention the existence of an afterlife, but only in contrast to Leá Monde’s cycle of rebirth and undeath. Aside from that, the only information we have about life after death comes from religious ceremonies held by either the Light of Kiltia or the Church of Glabados. (The funeral rites in the epilogue of Tactics and the opening of XII share the exact same wording, incidentally.)
I rather like that Ivalice doesn’t strive to make a sweeping statement about the existence of God, only about corrupt religious organizations. The story of Saint Ajora may have been a fabrication, but Ajora is much more of a Messiah-like figure than a god, and Ajora’s possession by Ultima neither proves nor disproves the existence of deities in Ivalice. There’s never any one moment where an Ivalice protagonist is forced to battle, say, Faram the Father… and I really appreciate that.
