Qual'do Herm was a male Aqualish who worked as a major for the Rebel Alliance in the Hidden Rebel Base on Corellia. Prior to this, he had studied alien surgery at the Scientarium Academia along with his friend I'klee'trao who specialized in acoustic technology. He used to be the best surgeon for 10 parsecs around Corellia, but had to stop when he could no longer deal with his nerves.
