My name is Rosabelle Schaeffer. I'm fourteen, four years older than my sister and have been in My father's creation Lyoko for fourteen years. I was here to oversee the destruction of a project but it never happened. Instead, Dad's program, XANA found me and found out that I held keys to this world. So to get what he wanted, he took me over to an extent and threatened to harm my family that had arrived on Lyoko. The only catch, I couldn't remember who they were, except my father. XANA had taken that memory from me to keep me bound to him. I live in a special sector that my father designed for me due to my inability to become Materialized back to Earth. XANA doesn't know about it nor can he get in. I follow XANA only to save the other member of my family, whoever they are.
I may be working for XANA, but that doesn't mean I'm controlled by him. There is this group of people that keep coming in and then leaving. They might have the key to my escape, and to be honest... I think I actually like one of them...
