OH SHIT THAT MAKES SO MUCH SENSE. It also explains why the demons can't help but be subservient to her since she would be THE leader of hell. She is also always depicted as a biblically accurate seraphim with 6 wings covered in eyes. I just fell in love with this story even more.
Also, her name? Evangaline, meaning "the word of God"? Peak. And a quick google search reveals "Rohanson" translates to "Spiritual Child" with Rohan meaning "Spiritual" in Arabic.

When the ML complimented MC on her dress, saying that she looked like the brightest star, I feel like that had some hidden meaning. After the god Rachel, the stars were the next most revered (but seen as disgusting and revolting by followers of Rachel), and the people who worshipped the stars were sorcerers who were exterminated. She’s a star, opposing Rachel’s influence and changing the faith of those who see her, while gathering demons and the like around her, like the sorcerers. I just find it fascinating.
