Final Fantasy VI

In the town of Narshe, Terra participates in an Imperial mission to seize a powerful Esper encased in ice. Upon locating it, a magical reaction occurs between Terra and the Esper; as a result, the soldiers accompanying Terra are killed and Terra is knocked unconscious. Upon awakening, Terra is informed that the Empire had been using a device called a "slave crown" to control her actions. With the crown now removed, Terra cannot remember anything more than her name and her rare ability to use magic unaided. Terra is then introduced to an organization known as the "Returners", who she agrees to help in their revolution against the Empire. The Returners learn that Imperial soldiers, led by Kefka, are planning another attempt to seize the frozen Esper. After repelling Kefka's attack, Terra experiences another magical reaction with the frozen Esper; she transforms into a creature resembling an Esper and flies to another continent. Upon locating Terra, the party is confronted by an Esper named Ramuh, who informs the group that Terra may require the assistance of another Esper imprisoned in the Imperial capital city of Vector.
