Every world has their own skeletons to deal with. Each has a past that results in very different cultures manifesting.
The Drengin used genetics to create super soldiers Called the Korath.
The Precursors was the name given to a collection of beings not even technically the same species to begin with.
Earth has several political groups largely based in geography and it's military force, over the decade, has splintered off.
The Altarians are made up of several distinct sub races. This should come as no surprise To anyone. They aren't humans. They simply look human for reasons outlined so e in Altarian Prophecy. the reason different sub races look different differs from race to race; from culture to culture.
To me, the suggestion that we shouldn't allow these civilizations to have different sub cultures or internal divisions strikes me as absurd. Of course there will be vying powers and internal intrigues. we will see them time and time again because sentient beings are messy.
i wouldn't get too uptight about the naming error. we are deep in the sausage factory here. It'll be corrected. Unfortunately, what happened to Elsys is tragic. She won't be coming back. It's not the Altarian Republic, it's the Altarian Resistance. It has been a very dark time.
