Fair enough, I couldn’t find any reference one way or the other except for presumption of the humans by humans part.
Though Ciri does show a way to be a female Witcher trainee with no signs but her own powers. Maybe you could choose a Lodge sorceress, an elven rogue style, a dwarven warrior or Witcher so they have their own weapons and skills etc.
I’m just spitballing here but as long as the game is well crafted and has Marcin Przybyłowicz do the music I am sold!
Ciri did the witcher trainings but didn’t undergo the mutations so she wouldn’t be able to use elixirs and wouldn’t have the usual witcher benefits. Also, the mutations would kill her because she’s a girl, so they can’t implement that. And her fate after The Witcher 3 depends on a playthrough so it might prove difficult to continue, unless they just make one of the endings the official one.
As fun as it would be to play any class in the world of the Witcher, I think the protagonist should be a witcher to fully focus on witcher builds etc. for the game to stand out from other fantasy RPGs. Perhaps they could introduce different witcher schools to choose/develop. But since the game will include Geralt, I sense he’ll be our trainer and hence it will the school of the wolf. Let’s wait and see.
