The Shadow Surgeons were an unidentified humanoid race that once served the Shadows. Serving their masters as medical technicians, they are known to have prepared sentient beings with cyberweb implants and installing them as living CPU's in Shadow Vessels, as well as examined potential hosts for Drakh Keepers. Following the departure of the Shadows after the Shadow War, this species remained allied with the Drakh, another race that were allied with the Shadows. They followed them to Centauri Prime and hid inside the many forgotten secret passages within and beneath the Centauri Royal Palace.
