RE: Representation of non-whites in medieval fantasy.
I understand and appreciate the argument that when it's strictly fantasy and an entirely fictional setting there's no reason people other than Caucasian could be represented. But I also understand that fantasy settings are frequently influenced by real history. Even though ultimately fictional, the cultures, architecture, topography, clothing, and art draw heavily from the closest historical time period and location. In the case of The Witcher universe all of this is built from a template of Eastern and Northern European middle ages, down to the colour of skin.
And I'm not stating this as an argument against the inclusion of non-whites, so much as the thought process and reasoning behind the aesthetic direction and why it's not exclusion with malicious intent, or nor (in my opinion) said exclusion is disappointing or offensive. It simply is what it is, and for me personally, as someone with an interest in diversity in settings and representation of people, the frustration comes not from deliberate historical influence in settings like The Witcher, but the absence of stories with settings where the alternative is more prominent. Give me a middle ages inspired setting that draws extensively from Spain, Portugal, Egypt, and so on, where European Caucasian is a minority, drawing upon those regional and historically relevant cultures and people. It sucks we don't have those.
