If you notice, ASOIF has ABSOLUTELY NO racial mixing in the north. They are all white. And if you compare the locations of witcher 3 to ASOIF, witcher 3 would be set in the north.

CDPR did not make the witcher world.

If you didnt notice, it takes place in the north, and there is little to no immigration in the witcher world. so please, fuck off with your feminist and blacklivesmatter bullshit.
