Hmm. Got to the Halloween party in my replaying, Caribdis seemed to draw a fair bit of attention towards us dressing as Eros, and made sure to say that Eros is the son of Ares and Aphrodite, and husband to Psyche, who we learned at the mansion party is the goddess of the soul or whatever, which is what inspired us to dress as Eros.
If we accept the MC as standing in for Eros, and try to fill in the other relations mentioned, I guess Calypso would probably be the closest one to Psyche? I guess I'm not precisely sure how souls would be involved with her powers, but if Eternum is a collection of afterlifes, then maybe being able to create portals to them would make sense with that? Maybe we'll discover some new aspects of her powers later too, with her powers now unblocked after the latest update, and with the doors of Acheron surely coming upon us within a couple updates or so. Acheron is the entrance to the underworld in Greek mythology, and we're supposed to use Calypso to open the doors of Acheron, so there might be something there.
I would have maybe said Idriel for Psyche since she'd be more straightforwardly involved with souls via the NPCs I guess, but Calypso fits better as being our wife than Idriel would. And I do suspect that Idriel is our "mother" of sorts, which would presumably place her as Aphrodite. As for Ares, I guess it would be the Founder. I'm having trouble putting it to words, but it just makes sense to me, and I am starting to get more on board with the thought that the Founder is our "father" of sorts. And I do suspect that there is some sort of romantic relationship between the Founder and Idriel. I mean, that's what happens in Calypso's story of Anima after all, the evil king woos her and then betrays her and captures her power.
Hmm.... I wonder if it is that Idriel is Anima, then if that could really mean that Idriel is the afterlife version of Anima, whom the Founder managed to find in her own afterlife and then capture. That could possibly explain why it seems like Calypso's story of Anima is just repeating, it is just happening again because the Founder managed to find a way to try it again after death. I dunno though. I'm still not completely sold on the "Eternum is just the afterlife" thing.
Anyways, it's been really fun playing all this back and sensing when there's a line or a sequence that you can tell there's something more to but we just don't know enough yet to say what exactly it indicates.
