Kezzia

Kezzia was a human colonist living on Gliese 581 D in the far future.

She was a member of the set-up team awoken from stasis in advance to ensure the proper function of the city. Kezzia was responsible for overseeing the pollination of the wheat fields by the Vardis.

While she was doing a routine inspection, Goodthing contacted her desperately warning her not to come back to the city, as the Vardis had begun killing anyone who showed signs of negative emotions such as grief. However, Kezzia didn't head her warning and at some point was killed by the Vardis.

The Doctor and Bill later came across her bones that were being used as fertilizer.
