A folk hero among the salarians, essentially the mythological founder of the practice of psychiatry. He famously defeated a demon with 1000 days of questions, a mirror, and a single gaze. He was the first salarian healer of minds, and over the years he and his students taught many others how to heal the psyche, among all the clans.
"Even though we now have medicines and therapies and surgeries unimaginable to the first healers, every salarian who helps the mentally ill can trace the names of their teachers, and their teacher's teacher's, and all who taught them before, back to Siirit Empata."
The legend is recounted in detail here.
