I do believe in reincarnated Deities, as to be deities are a race of beings. While there being no such thing as a reincarnated God/Goddess by title alone.
However, sounds more like the usual demon seen as an old God when a demon is just a demon not a God. Then again I believe in reincarnated demons too so lol.
No. We can recognize each other from the pack of humans. Every race that is incarnate as human as its own flavor (energy). But with that I usual ignore other pantheons and stick to my own family.
Thats the dream isn’t it? A goddess in the flesh. I am pretty happy with Eris though. I wouldnt change what we have for a second, because I know if she wanted to be with me in the flesh she would, and I would never ask anything of her that she would dislike.
