Golin Shel-la was a humanoid male and the leader of the Ennis for several hundred years. Shel-la and his group, as well as Zlangco's Nol-Ennis faction, were exiled to a moon in the Gamma Quadrant by his homeworld Tevlin-De's leaders for not finding a way to stop their long-running war. As an additional punishment, Tevlin-De's leaders created nanite-like bio-mechanical microbes that resurrected people after death, forcing the Ennis and the Nol-Ennis into an eternal war. Shel-la and his people died countless times over decades and were always resurrected and healed of their injuries. (DS9 episode: "Battle Lines", DS9 novel: Rising Son)
