Sven was Norma's teacher when she was young and lived on the Mainland. At some point, Sven discovered Norma's abilities as an Eren and enrolled her in an expensive school. The aloof Norma, however, was never serious and often did not believe the things Sven told her. Eventually, he left in search of the Everlight and did not return. Some time later, Norma heard news of Sven's death aboard the Legacy and decided to leave her home in order to travel to the Legacy and find the Everlight in order to complete her teacher's work.
