Biography
Dr Corwyn was born around 2044 (PROSE: The Wheel in Space) and married a man who died in the asteroid belt circa 2076. By 2079, she was the medical officer aboard the Wheel and second-in-command to Jarvis Bennett.

Concerned that there might be life aboard the Silver Carrier, Dr Corwyn tried to convince Bennett not to destroy it. She examined the Second Doctor and Jamie McCrimmon upon their arrival, reporting to Bennett that Jamie was lying about their presence on the Carrier, and introduced them to Zoe Heriot. She believed the Doctor's concerns about the Cybermen and attempted to persuade Bennett of them without success.

Dr Corwyn managed to warn the Doctor of the Cybermen's plan to poison the air supply, but was killed by a Cyberman whilst trying to flee from it. The Doctor informed her colleagues of her death, telling them that she sacrificed her life. (TV: The Wheel in Space)
