Isoldiians

The Isoldiian are ancient race of Humanoids [appearing several hundred thousand years after the Progenitors disappeared] and became masters of cybernetics and genetics.

Although these two masteries almost caused the downfall of their race, through genetics they tried to crate the perfect body and then enhance it with cybernetics, unfortunately an unknown virus escaped and contaminated all of their genetic databanks and the population so that when they were born they only had a torso and head [although all the parts of the torso including genitalia were still intact].

Unfortunately even with their advanced genetics knowledge they were unable to ever fix the problem and instead moved on to the cybernetics knowledge and created carriaged with arms and legs and other enhancements to help their now physically crippled race.

Now after thousands of years their cybernetics is the most sought after and have become works of art.
