So is there an explanation why the First has the same racial variations as the Source with this new information? I just assumed Hydaelan intentionally turned everyone into the same multitude of races then repeated that variation accross the reflections, now it's evolution? I get that The source and the reflections were carbon copies of eachother straight down to insigificant details and so it's possible whatever environmental conditions combined with the unique physical deficiencies the sundered ancients had would end up eovlving in the same ways, but I mean it's kind of a stretch of believability. "It's just Hydaelan's magic" was a simpler explanation.

Then again the Amal'jaa, whom I guess are also sundered ancients since they appear on the First too, are hairless on the Source but their First equivalents are covered in fur suggests evolution was similar but not 100% the same for everyone across reflections.

But I'm really curious how the sundered ancients would evolve into actual beast races like the Hrothgar.
