Progenitor

The Progenitors are the legendary first (and doctrine dictates only) species to evolve intelligence and technology to the level of space-flight without being genetically engineered by another species. They began the great chain of uplift from which all species owe their patron-client lineage. While revered by all races in galactic civilization, no specific information about them as a race survived in The Library after their disappearance billions of years ago.
