As for culture, can I have a bit of Indian influence? also around what year is it?  Also, what are the limits on ethnicity and stuff?

The year isn't important from a fiction-nonfiction comparison. All you need to know is "Bronze age". Like-wise, the area is maybe no larger than a quarter the size of the northern bulge of Vietnam and within the tropical zone. So while geography or hunting range might separate tribes local to the area they'd be within the same cultural feel. Like-wise the farming refugees coming east to escape persecution or annexation by the western Emperor would share a common ancestry best described as not being Indian.

The map to be honest just isn't that big yet.
