Terra Branford/Opera Omnia

Summoned into the conflict by Materia, Terra is recruited by Mog at the Snowy Peaks of Crudelis. She is initially under the control of Kefka and set as the pilot of a Magitek Armor unit. She engages Mog's party and is defeated by them, whereupon a magical device falls from her head. Although some in the party worry over her allegience, they decide to help her. Terra remains unconscious for part of their journey through the Peaks. When she awakens, she explains that she had fought Kefka and was defeated, whereupon he brainwashed her and forced her to fight.

Terra retains most of her memories except those of her time in the new world. She is deeply remorseful over her actions, but Cloud and Bartz assure her that it wasn't her fault. Believing that Kefka wishes to destroy the new world as well as their own, Terra immediately agrees when they ask if she will join them. Though defeated by Kefka when she was alone, she willingly confronts him when the party finds him again.

Although she appears in the same circumstance at the beginning of her own game, Terra is a member of the Returners when she enters the new world, as she knows Shadow and refers to him as a friend when they encounter him in the Palace of Malitia. She is, however, irritated with him in the Imber Manor when Layle tells her that Edgar is leading the Returners, a fact which Shadow neglected to tell her.

As doubts surface about their mission in the world and Mog, Terra tries to reassure the Warrior of Light that they've made their own choices. Although she acknowledges that she doesn't know how far they can believe their moogle guide, she still chooses to trust him in spite of the warning from Edgar that Layle passes along. Her trust in Mog is damaged in Utopia Niveus when he admits that he can't be sure none of them will be tempted by the Emperor's offer. Terra is appalled and reminds him that he personally brought each one of them into the party. She is even more horrified when Mog accepts Kefka's dimensional coordinates. After it is revealed that Mog has been possessed by the Blackened Will, Terra is the most insistent that he can be saved and returned to his normal self.

During the party's journey into the World of Darkness, Kefka again resurfaces with a plot to "rebirth" the Blackened Will using the Dark Manikins of Celes and Terra as vessels. Terra is particularly determined to put an end to Kefka's destructive scheme, just as she did in their homeworld, in spite of the others' concern about her emotions. When the party encounters the broken and berserk manikins, she and Celes both insist on fighting them and allow them to pass away peacefully after their defeat.
