Fern destroyed the matriarchal lineage system which was the the rule in Farville (previously known as the Farming village). He found men worked too hard to just let women rule and keep all the wealth they gained with their sweat and blood. And from his personal experience, there was never any guarantee that the women weren't seeking men from other clans and birthing their children too. He did this through force. Anyone who resisted or expressed any type of differing opinion was enslaved in the farming fields annexed to palace and the other affluent families. Quillaq, Nuru, and his grandson Ghalib were of great help to him during this time.
