Need some advice, in my mod im using some myths to provide a starting plot, it starts when most civs are starting to develop, India will be the most developed area with the harappan culture in place. And im using the myth of the lost continent of Lemuria, where most or part of the inhabitants of india came from. There's one or more theories that see Aryans and Dravidas as two tribes of Lemuria that were in constant wars with eachother, and when Lemuria sunk they migrated to India and took their wars with them. There's the Aryan invasion theory that says the Aryans were invaders from the north, and there's the other theory thats gaining support (i think) that says the Aryans were indigenous to india and migrated out. I prefer the later one, combined with the Lemuria myth, the Aryans came from Lemuria to India, and later migrated to other areas.
But what about Harappa, should I make them a separate civ or combine them with the Dravidas from south India? Or were they Aryan? Do I make another civ to represent the Aryans? Im thinking of Aryans as some sort of culture group, not a unique civ, should I think of the Dravidas in the same matter?
What about names for civs to represent the two "cultures"? Aryan and Dravidian
Thanks in advance, need to make this decision so i can move on to other areas of the mod.
