By the 24th century, Morgan was several centuries old, and was seeking a way to end her immortal existence. Not much about her earlier life was known except a few scant details such as claiming that she had served aboard the USS Enterprise at one time. When Montgomery Scott met her when she visited Risa, he mistook her for Christine Chapel, calling her "Christine." (NF novels: Fire on High, Renaissance)
Charles and Robin Lefler
In 2344, Morgan met Charles Lefler and the two began a physical relationship. Morgan soon became pregnant for the first time in her centuries-long life. Charles and Morgan were married, and in the year 2345, Morgan gave birth to her only daughter, Robin Lefler.
Morgan quickly determined that her daughter had not inherited her ability to heal all wounds.
In 2354 Morgan, suffering from depression over the thought of outliving her family, "disappeared" for the first time. She would be absent from her family's life for weeks at a time in the years that followed, without any real explanation.
Morgan started seeking the advice of a therapist named Dr. Kevin Pointer, who was unable to help her with her depression. When her daughter, Robin, was 17, Morgan had to fight off a terrible urge to kill herself and her daughter, fearing her reaction to learning the truth about her mother. In the end, Morgan was unable to end the life of her only kin. (NF short story: "Lefler's Logs", "Alice, on the Edge of Night")
In 2363, Morgan faked her own death in a shuttle accident, and traveled the galaxy hoping to find a way to end her immortal life. She and fellow immortal Tarella Lee, whom Morgan had long known, sought out the god-like Prometheans, in hopes that their powerful technology could end their lives. (NF short story: "Lefler's Logs", "Alice, on the Edge of Night")
In 2369, while on her quest to find the Prometheans, Morgan was imprisoned by the Momidiums of the Gamma Hydrinae system in Thallonian space, for trespassing. The sentence for trespassing in Thallonian space was death, but Momidiums chose instead to imprison Morgan.
Starfleet sent the USS Excalibur, where Robin was assigned as operations officer, to make the exchange. At first, Morgan was unwilling to see Robin, and even tried to steal an Excalibur shuttle to escape her.
Morgan and the Excalibur soon encountered Tarella Lee on the planet Ahmista. The Promethean weaponry that Tarella found on Ahmista had driven her insane, and in her madness Tarella destroyed Ahmista's native population. In the end, the weapon proved strong enough to end her life after Tarella gained a semblance of sanity and realized what she had done. (NF novel: Fire on High)
- The Prometheans shared the same M.O. and abilities as the Cognocenti. It is possible that they are the same race.
Morgan had finally found a way to end her existence, but now that she was reunited with Robin, she found that she was unable to put her daughter through the heartache again. She chose instead, with the blessing of Excalibur Captain Mackenzie Calhoun, to move in with Robin on Excalibur. (NF novel: Fire on High)
Morgan, who had served in Starfleet in more than one of her incarnations over the years, made herself useful on the Excalibur in many ways, including assisting the ship's science division, and running the helm during the Gateways Crisis. (TNG short story: "The Other Side")
Morgan served as the ship's computer for several years, until at least the year 2379, when she temporarily transferred her consciousness to a holodeck on New Thallon following the death of Robin's husband, Si Cwan. (NF novels: Being Human, Gods Above, Missing in Action)
Morgan's holographic form (and computer-based consciousness) returned to the Excalibur, (NF comic: "Turnaround, Part I") but became insane with power, threatening Starfleet officials, and was eventually destroyed by a computer virus developed by The Doctor, Seven of Nine and Soleta. (NF novel: Blind Man's Bluff)
As is noted above, Morgan resembles Christine Chapel, may be related to Lwaxana Troi, might have had the identity of Number One, and sounds like a Starfleet computer. This is an extended joke concerning the fact that all these roles were portrayed by Majel Barrett.
