A Sith-Humanoid hybrid 5000 years before the Battle of Yavin. He was thousands of years before the Great Hyperspace War and Tens of Thousands of years before the Sith Wars.
A highly guarded secret of the Aristocra of the Chiss Ascendancy, the knowledge of who the Sith Lord Marka Ragnos was and what he meant to the Chiss.
We always knew that we, the Chiss, were genetically engineered. Sith Lord Ragnos created us, in his “own” image and we, the Chiss are his disciples to bring forth his return.
But much has changed since that time. Ragnos died. We migrated to The Unknown Regions and populated the planet, Csilla.
In Ragnos’ genetic creation of the Chiss, he gave us Force Sensitivity. Since our colonization of Csilla, our scientists have done everything to suppress the Force in Chiss.
I believe, it is the reason the Decadent Chiss were democided at the Csillan equator. Then the Chiss Ruling Families decided to excise the genes responsive to the Force. Enter crossovers stopped at tetrad meiotic division with a suicidal poison vectors. More Chiss died than those who survived. When finally, there were only three Ruling Families.
Over hundreds of years, we had more Ruling Families to encourage genetic diversity. Undesirables have been removed from our society. We are an elite military in The Unknown Regions with great efficiency to all planets in Chiss space. We are an oligarchy inclusive democracy society where our pursuits are for the Chiss, family, houses, and our continued existence.
