Illyrian
The Illyrians were a spacefaring humanoid species native to the Delphic Expanse. Their original settlement was located in the Vaultera Nebula, though they also had colonies across a wide swath of space, including one located at Hetemit IX.

History 
In 2154, the Starfleet vessel  – badly damaged by the recent Battle of Azati Prime – was assisted in its repair efforts by an Illyrian starship that had been disabled by an anomaly field. Enterprise helped the Illyrians in turn. They were unwilling, however, to trade their warp coil because not having it would mean a three-year journey home. Needing the warp coil in order to save Earth from the Xindi, Captain Jonathan Archer and several MACOs boarded the Illyrian craft and stole their warp coil, leaving the Illyrians stranded. ()

Due to the ban on genetic augmentations in the United Federation of Planets, in the 23rd century, they were considered outcasts in the Federation. Illyrians could not join the Federation or Starfleet, and there was a directive against mixing Human and Illyrian blood. The Federation also banned the use of any Illyrian medical technology. ()

Physiology 

Illyrians were avid practitioners of genetic engineering; they believed in adapting their bodies to the new planets they settled, rather than changing the planet to suit themselves. As a result, Illyrians varied widely in appearance as well as in capabilities. 
Some Illyrians were externally indistinguishable from Humans, while others exhibited various traits such as cranial ridges, webbed hands, pointed ears, and differently structured eyes. 

Some Illyrians, like Una Chin-Riley, were also modified with enhanced strength and an immune system that could literally burn out infectious agents from the body rather than rely on antibodies. (; )
