Not only is she a transmigrator, she's also the author of that f*cking novel phil treats like a bible. Well not anymore but she used to.
The original story used to be very different than the one written on that book. But one person didn't like it, she hated philomel with all her being and decided to write her own version where phil is a villain and the princess is the female lead.
In the original story, philomel didn't even do that much evil deeds, like any minor villain you'd see in other manhwas. Not evil enough to want someone dead or even try to kill them.
Anyway, this bitch wrote a novel and many people liked it and it got famous..then she somehow ended up in the novel..in princess elincia's body. Mind you the og princess is still there..just that another soul has the control of her body.

Yeah. And i read the spoiler long ago i mistook some things. The original was an otome game, not a novel. Here's the piece of spoiler i got from NU.

The story really begins with the fact that the in the original story of our MC (Philomel) is from a otome game. In the otome game, Philomel is just your average villainess; however, she isn’t a bad-bad person. Philomel in the otome game is just a petty child who wants attention. She doesn’t do anything evil, the most she gets is a slap on the wrist.
While playing the otome game in real life, the author in of the book that Philomel reads gets upset and decides to wire a fanfic/spin-off story of the otome game. Let’s call this person author. So, in this fanfic that the Author writes, it’s a darker version to the otome game. The Author decided to write a darker version because she hated Philomel and wanted Philomel to have a bad ending. The Author overall just hated the original otome story. This is the story that Philomel reads and decides is the prophecy. The story of how Philomel gets executed because in the otome game original story, Philomel doesn’t get executed. The real life audience liked this darker version to the story so much that it becomes an official story to the game. From this point on, the author of the fanfic does and gets transmigrated to the current world and story of Philomel.
And this is what happened. The princess soul is still there somewhere, if not in her og body. I'm not so sure now. And about how this fake knows so much about the imperial palace. Because she played the game before, so she knows.
so elincia is a transmigrator right? it makes the most sense. ig she’s trying to get her happy ending and is confused as to why philomel is acting differently lmaooo
