Elix Barus was a Betazoid diplomat in the mid-24th century. In the early 2350s, he was part of a diplomatic mission to Rutia IV. In 2352, Barus and the rest of his team were assassinated by Ansata terrorists. He unknowingly left behind a son, Ciaran Shean, the result of an affair with a Rutian woman. (Star Trek: Pendragon)
