Hey all, I had a thought that I haven't seen posted here before. Tell me if I'm repeating something that has already been volunteered.
I'm playing through PSIV again, and the coincidence between Alis and Alys has always been something that I found interesting. In addition to having (at least in the translated edition) the same sounding name to the heroine of Yore, Alys, Rune and perhaps Grandfather Dorin seem to have the makings of a Dark Force fighting posse, one that the Lutz of the time was likely assembling for around the 1000 year mark.
I'm thinking that up until the unexpected death of Alys at the hands of Zio, Rune could have believed that she would be the heroine to defeat this iteration of Dark Force. There was no knowledge of the Profound Darkness' existence until far later in the game, and it could explain Rune's switch from discrediting to supporting Chaz following Alys' death. When you can't have your first choice, you support your second
