Katerina was a young woman who wore a long Victorian dress. She had long, dark hair which was sometimes covered by a bonnet.
In the past she appeared to be a loving mother.
At some point she met the Earl of Millennium and became close enough to him to cry when he 'disappeared'.
Then when the Earl turned into two infants, she adopted both of them, and named them Mana and Nea. She raised them as her own children in the Campbell Residence. When Mana became ill she watched over him day and night until he eventually recovered.
Some time later, Katerina was badly wounded by the Earl of Millennium, who then announced to Mana D. Campbell that everything had gone back to the way it was. Despite her injuries, it is implied that Katerina survived.
