First: Thanks
@col_caboom for digging out this threat. I always thought that it is strange not to see a discussion of the Empress Ending in the forum. I never would have thought that the last post there would already be half a year old
In my opinion the empress ending is not the worst one. There is always the bad one where Ciri and Geralt are dead. From an emotional point of view.
But I would go with
@Euripides66 that it is the worst one for the continuity of the story
From my point of view, with the knowledge from the books, Geralt would never trust Emhyr enough to bring Ciri to him. This would be completely out of character. He may have abandoned his incest-plans for her in the last moment, showing that he at least has a bit humanity left and not killed everything within himself for the reason of state, but he is responsible for the death of several persons important to Ciri and has been shown as a calculating and manipulative person.
For Ciri this choice seems also unlikely. At one point in the books, I think it was in Tower of the Swallow, she wanted to become Empress, as she heared that that a pretender is going to marry Emhyr and get all the luxus while she was sleeping in barns and living with a band of thieves. Aside from this one part of the books, in which she was a lot of time on fisstech and killed people for fun, she never showed interest in becoming a queen, marry a prince, or being someone important. She wanted to be free, she wanted to a witcher, she wanted to be with her true family, Geralt and Yennefer.
As for her relation with Emhyr, I don't think that she would give him a chance as father. I have read somewhere before that he told here that he is her father in the books when he called her daughter at the end of Lady of the Lake. I have read the german version and there it is translated with Töchterchen, which could also be a form of adress for a young girl by an older man. I'm not sure what the polish version says but by my interpretation she does not know at the end of the book that Emhyr is her father. If she would know that her reaction would be much more shocked. And once she would know the whole story about the death of Pavetta, Emhyrs plans and everything, I think she would be disgusted of him.
As the game ignores the incest-plans and fake ciri it may be better to regard it as a standalone. Without ignoring this two things, it would also be impossible to make an Empress ending at all.
"Okay, the woman you married is not Cirilla of Cintra, but this is the real one and she is your daughter. WTF??"
In the game the Empress ending is explained as Ciri embracing her heritage and accepting the responsibility. She ignores what Emhyr has done (in the journal is only stated that he was responsible for the death of some people Ciri cared for if I'm remembering right) for the greater good and becomes a great empress. So it is shown as a selfless ending.
In the witcher ending she is with Geralt for some time and afterwards hunting monsters alone. She has fun and is free to do what she want. But she only helps people through killing monsters. So it is shown as more selfish in comparison to the Empress ending.
But also in game Ciri stated several times that she wanted to be free. No longer controlled and manipulated by other peoples who have plans for her. Doing the things she want.
But if you have the Empress Ending she decides to give her newly won freedom, no white frost, the wild hunt is gone, up and go to Nilfgaard, leaving her true family behind, go to the snakepit the nilfgaardian court is, possibly full with people like Phillipa and Siggi, marrying Voorhis, and trying to reform the Nilfgaardian Empire.
It sounds good. You could say that she is now grown up, accepts the reality, gives up her dreams and tries to improve the world. But it does not feel like this is Ciri. It does not feel like something that will make her happy. And I'm also not sure if she will succeed.
Forgiving Emhyr: unlikely
Marrying someone she don't love and know: Impossible
After being chased for nearly half her life by people trying to use her and risking her live to save the world just giving up her hard won freedom: Very unlikely to me.
Ciri is also no politician. I think she would hardly make compromisses at things she detests and would earn enemies through this and she has also no experience with politic and intrigues. Eddard Stark was also a good person who tried to do the right things. I think most of us know what happend to him.
Also the problem with the North still remains. What if Kaedwen rebells against Nilfgaard? What would Empress Ciri crush it with all force? Make concessions? What if the other conquered kingdoms want the same? What if they want to fight until Nilfgaard leaves? What will the nilfgaardian military and nobility say?
In the end it is up to everyone which ending he or she choose, but in my opinion the Witcher Ending fits better to the overall story. And considering the books it is no choice at all for me.
