Back in the day, Katerina was a young woman wearing Victorian clothing. She had darkly colored hair, and wore a long dress and a bow tie. She is now an old lady with long straight white/grey hair. She has a strong nose and wears a long dress and earrings.
In the past he appearead as a loving and smiling mother. She seems to be a nice vigorous lady.
At some point she met the Earl of Millennium and became close enough with him to cry when he 'disappeared'.
Then the Earl turned into two infants, she adopted the both of them, named them Mana and Nea, and she raised them as her own children.
When Mana became ill she watched over him day and night until he eventually recovered.
At some point, an a bit older Katerina was badly wounded by the Earl of Millennium. The Earl then announced to Mana D. Campbell that everything was back to what it used to be. But Apparently Katerina survived.
