Selar
Doctor Selar originally appeared in the TNG episode "The Schizoid Man", where she was played by Suzie Plakson. She is the Chief Medical Officer on board the Excalibur. It is revealed in the opening New Frontier novel story arc that her husband, Voltak, suffered a fatal heart attack years earlier when they were consummating their marriage during pon farr. As a result, she never completed the act, and was in a suppressed state of incomplete pon farr until she met the Excalibur's Chief Engineer, Burgoyne 172. The two began a relationship, and Selar bore them a son, Xyon. In the 2009 novel Treason, Selar, desperate for a cure for the rapid ageing that afflicted Xyon, was telepathically manipulated by a race called the D'myurj into kidnapping Cwansi, the infant son of Robin Lefler and Si Cwan. In atoning for her act by rescuing Cwansi, Selar sacrificed herself by destroying the D'myurj's base of operations in an explosion that took her life. Previous to that, she decided to ease the hurt she had done to Burgoyne by using a mind meld to erase the pain from his memories of their relationship.
