Kirena Morok was the creator of the Guild of Poetic Justice on the patriarchal human colony world Kapone, and was the sister of the 8th Doctor's previous companion Jadi Morok. The child of a violent world, she died peacefully at home aged 45.
Life before the Doctor
The eldest of a large number of siblings, she raised her youngest brother Jadi after his mother died in child birth.
Life with the Doctor
Kirena died a number of times. Her first death was on January 12, 2101 in a restaurant in New Cheadle, where she was torn in half by a bomb intended for a local politician. Her biodata was grafted onto a police detective named Ezekial Barnes as part of her murder investigation; although such grafts were supposedly just data, she was able to take control of his body until the Doctor managed to transfer her graft to a clone of her original body, a process fatal to the original host. However, crucial information was lost during each operation, essentially leaving her with Alzheimer's Disease. She returned home to Kapone to witness the birth of her neice, phlegmatically content with her fate but unable to remember why she'd wanted to travel with the Doctor in the first place.
Life after the Doctor
Over the following decade, she lived each day as though the next would be her last. She found herself thinking of ideas for things to do, clever last words to utter, and scrabbling for pieces of paper to write them on. Every day would be full of great new ideas. Every day, the pile of papers would grow larger, as the memories that made her who she was faded away. Admittedly, some days were better than others; some days she would forget who she was altogether, while others she would almost be her old self. She was always surrounded by those who loved her, though. During this time she married, bore a son and moved into a cottage at the bottom of her brother's garden. With both men busy and frequently offworld, it fell to the women of the Morok household to provide the almost constant care she required until the almost total return of her memory heralded her final day.
