At a very young age, Quistis Trepe's parents were killed in the Sorceress War, a young lady by the name of Edea Kramer looked after her amongst the other orphans who are also her current friends. Several years later, she was adopted by a family, but because that didn't turn out very well, at the age of 10, she joined the Balamb Garden, and trained using the Guardian Forces. Because of their power, her memory was lost and ceased to remember her childhood and the orphanage. Quistis is seen as a child prodigy, as becoming a SeeD and instructor at the age of 15 was unheard of. She tought many students which included Squall, which we now see links their fates together. However, at the SeeD graduation ball, she received a notice that her permit has been revoked due to the fact that she was unfit to be a teacher. She continues her life as part of the SeeD and to save the world.
