Sara Kingdom

Sara Kingdom was a security officer from the 41st century who joined the Doctor and Steven Taylor during their battle with the Daleks. She was killed when the Daleks' Time Destructor was activated on the planet Kembel.

Biography
Sara was a Space Security Agent, the sister of Bret Vyon, another agent who was aiding the Doctor in trying to defeat the Daleks. Told that Vyon was a traitor by Mavic Chen, the Guardian of the Solar System (who was in league with the Daleks) and ordered to kill whoever was working with him, she shot her brother and was about to do the same to the Doctor and Steven when they were all transported across space to the planet Mira. There she learned, to her horror and grief, that her unquestioning obedience had not only led her to unjustly kill her brother, but also that by doing so she had prevented Vyon from warning Earth of the Dalek plot. She then joined the Doctor in his fight.

When the Doctor activated the Time Destructor as part of his plan to stop the Daleks, he ordered his companions back to the TARDIS for their protection. However, Sara followed him, not knowing the nature of his plan but concerned it might fail. As a result, she was caught in the field of the Time Destructor as it rapidly aged everything around it. While the Doctor, being a Time Lord, could withstand the effects better, Sara, being human, could not. As Steven and the Doctor watched helplessly, Sara died, her remains aging to dust.

Sara was by turns aggressive, independent and ruthless in her pursuit of what was right, a single-mindedness that blinded her to the larger implications of her orders. Meeting the Doctor changed that, and she turned her formidable skill and intellect to the defeat of the Daleks.
