The Rig Viddikira Clans

These are people who lived in the east of India, clans that lived in the Rig Viddik age. The western opponents of King Sudhas include the Dasas, the Prithus or the Parthavas. Then we have the Shiva clan, the Dasa clan, the Alina and the Shimhu clan. Do we have more western clans, the Sakhaz and all that? That's later on and so on.
