Emeraude is a scientist from the planet of Fodra. Together with Director Cornell, they found and tried to raise the being known as Lambda. Eventually, against Cornell's wishes, Emeraude decides that Lambda has become too much of a threat and that he must be eradicated. Cornell does everything in his power to stop Emeraude. He eventually manages to help Lambda escape onto a shuttle and fly to Efinea at the cost of his own life. In order to try to stop Lambda from living, Emeraude designs a being known as Protos Heis whose sole purpose is to destroy Lambda. Emeraude, unable to see the fruits of her research, presumbably either turns herself into a humanoid, or injects her consciousness into a humanoid that looks just like her. She then freezes that body in a cryo chamber with the humanoid Psi to look after her. She remains there for 1,000 years until Asbel and his friends find her.
 In Game
Psi awakens Emeraude when Asbel and his friends find her. When asked what happened to the planet of Fodra, Emeraude tells them that Lambda was the cause of it all, when in fact the scientists of Fodra had shut down it's core so it wouldn't kill the human race. Asbel's group, who doesn't know better, trust her completely on the subject. Together they travel to a place called the Citadel to repair Sophie who is in fact Protos Heis. Emeraude heals Sophie, but also reignites her fierce desire to destroy Lambda. The next time the group runs into Lambda infused Richard, Sophie tries to blow herself up to take Lambda out. Asbel is shocked by this turn of events but Emeraude tells them that this is simply how Lambda must be destroyed. The group eventually defeats Richard and forces Lambda out of him. As Lambda is suspended in the air, a crazy thought crosses Emeraude's mind. She takes Lambda into her own body in hopes of him working with her to restore life to Fodra. Lambda's power quickly overwhelms Emeraude who is then put down by Asbel and his friends.
