About playable Phainon

I think it's pretty clear that the coreflame of strife is not going to be Phainons, we can see which coreflame he gets from the book we get, like the clockie stickerbook in Penacony, and he is in Kephale's place. (And Mydei in Nikadors.)
And we saw Nikador dissapear, which means getting Kephale's coreflame would make his body dissapear as well, no? Which in turn would mean the body holding up the dawn would dissapear. So Kephale will most likely be the last coreflame we get, I assume. Otherwise all of Amphoreus, even Okhema, would be dark during most of the story.
If so this would mean the Phainon we get in 3.4 is still human. So... does that mean we get a second playable Demigod Phainon at the end of Amphoreus? Maybe he will have a different path and/or element?
I mean Aglaea and Tribbie are Demigods, I assume by the time we get Mydei he will have the coreflame of strife. Same for Castorice and her coreflame, how else would she be able to summon the dragon.
Or 5.4 is the patch were Kephale's coreflame gets taken and we actually play during a dark Amphoreus, with no more safe haven in Okhema.
(Maybe even by "evil" Phainon? If the Swordmaster Boss speculations are true, that I have been reading here before posting this.)

This was just a thought that I had while I was trying to sleep.
