Ishten, I hear what you're saying but this is what is said in the OP:
"It doesn't make sense in this medieval European setting to darken the pigment up of one nation. Where do these sub-Saharan esque people come from? Why aren't they more prevalent considering that historically, negroids reproduce more rapidly than Caucasoids and negroid features are dominant compared to recessive Caucasoid features when interracial mingling occurs?
What are the Rivaini people? They cant be white, gypsy and black. If there are both white, gypsy and black people in Rivain, are there any racial tensions?"
Like, okay, you want to make a point about wanting to understand more about Rivain! So cool! We all want to see it all, play it fully, experience the culture for sure.
But now Dragon Age is medieval? Ah yes, I recall my ancestors had to fight the white horned giants from the northern isles! Then they visited a spirit world which was physically accessible by thinking really hard or by having enough poison, magical rocks! Or they popped down to the subterranean kingdom that spanned continents so that they could take tea with a giant boob monster!
I would also love to hear more about if the DA creative team has thought about how they choose to represent racism and race in the DA world. But, the lack of people of darker skin tone to this point could very well be due to ignorance from a largely white creative team as much as the engines. Not a hateful thing but that's often how racism works, white is the default and if you are white, you don't realize that.
So asking if Rivaini people are being represented as darker as the series progresses isn't necessarily offensive but the context of that question is absolutely offensive in this case.
