Rebecca Horne was the teacher of Amanda, Henri Valjean and Luther. She was born in the year 1200 BC in Mycenae. She became Immortal after being killed by a jealous slave. In 850, Rebecca met newly Immortal Amanda who she taught about Immortality, The Game, how to fight, and they become good friends. Amanda, however, could not let go of her thieving ways and, and one day, tried to steal the crystal Methuselah's Stone in Rebecca's care. She was caught, but Rebecca forgave her. Amanda was moved by this and started to learn how to become a proper lady and to have a proper life. Amanda eventually left Rebecca's abbey, a refuge for Immortals, in 853. Rebecca gave one part of her crystal as a parting gift, as she had done with other pupils.
