On top of the other Wolf School characters that may or may not be alive by the end of the third game, and at a minimum that's one other person, there are also the other schools that could be used as a way for custom character creation. Wolf, Bear, Cat, Gryphon, and then all the others added later like Viper from the second game onwards, Manticore from the third game [used as a potential DEI excuse since the others were all white dudes], and now also Crane which is from some other story, means a lot of potential for a player created story rather than yet another RPG where players take the role of an established character. But then that has its own merits since it can flesh out a character far more than someones shitty OC so pros and cons both ways.
The Witcher, no. Other witchers, yes.
