The Hexadric Hegemony and its successor state were both ruled by the six matriarchal dynasties.
These were the modern family organizations that had come to dominate the Hexer people since they established their roots in the Komodo Star Sector four centuries ago. Their power over their own society had become so entrenched that no other Hexer dynasty managed to challenge their rule.
Even the hasty and messy evacuation to the Red Ocean after the Hexers lost the Komodo War did not change this fundamental status quo. The six matriarchal dynasties retained enough of their wealth and power that they thought they could continue to stay on top even as greater developments affected the rest of human society.
They were wrong.
Another influence within the Hex Federation rose up as of late. Many Hexers started to display less deference towards the matriarchal dynasties. This was a concerning trend to the established rulers.
