Sdan was a mixed-race man of the 24th century. He was a mercenary in the Silver Paladin's band. Sdan's heritage was a mixture of Human, Orion, Romulan, Vulcan, and, he joked, Aldebaran shell-mouth for stubbornness. His great-grandfather was a Human man, a trader who married an Orion woman, and began a successful hybrid line, with Romulan and Vulcan following. They lived within the Federation. Sdan's ancestors were intelligent, producing scholars, scientists, mathematicians, and doctors. They were also prolific, and Sdan had three brothers, five sisters, and uncounted cousins, all some variety of scholar.
