|Affiliation:||Lyran Star Empire, Lyran Starfleet Medical|
Dr. Mandy Guilmain was a medic that served, alongside her sisters, Cindy and Sandy, onboard the Stoneship. All three of them were capable to fly Lyran shuttles in combat and (presumably) as space ambulances. (Star Trek: The Stoneship Files: "Highly Illogical")
Upon departure of Sulivac for the Zedgar, Mandy became both the chief medical officer and the first officer of the Stoneship, taking a liking to Katola and Peokaa, even briefly becoming a college counselor to them. It was also revealed that she studied at Kinda Sorta College (a fresh matriculant there as of My Carpet, Tis of Thee, set in 2385) before attending medicine school at Spoiled Rotten University. In order to put all three sisters in college, the Guilmains took a mortgage to pay for college and medical/dental school. (Star Trek: The Stoneship Files: "Educational Armageddon")
