FF3 Storyline Summary

As the Empire grows, a resistance group forms, calling itself the Returners. Their members slowly grow in numbers, and a group of them eventually sets out to confront Gestahl and the Empire. Along the way, they find more companions, and discover that Espers are still around - and can give their magical powers to humans. Finally, the group reaches Vector, capital of the Empire, and finds that Espers are being experimented on in a laboratory there. Then Kefka, one of Gestahl's generals, arrives and sees the transformation of Espers into Magicite as they sacrifice themselves and give their powers to the group. The group is forced to run from Vector; they decide to look for the Sealed Gate to the Esper world and seek help from the Espers that remain there. However, when they get there and manage to open the gate, the Espers that fly out head straight for Vector, and the gate closes again and is blocked off by a rockslide. The group returns to Vector to find it demolished by the Espers; Gestahl admits that he was in the wrong to seek power and says he will stop his war. Kefka, meanwhile, is (supposedly) sitting and stewing in a cell for his crimes, including poisoning the people of Doma Castle. The group then heads again for the Sealed Gate along with Gestahl, so he can convince the Espers that he wants peace. However, it turns out that Gestahl had no intention of asking for peace; instead, he and Kefka find their way onto the Floating Continent, where the three "Statues" - three powerful mages from the War of the Magi who ended that war by drawing all magic into themselves and turning themselves into stone - are located. Realizing Gestahl's plan, the group goes after him in an airship. They find Gestahl and Kefka at the Statues; as Kefka gloats over their newfound power, Gestahl realizes that Kefka may have more on his mind than just being a part of Gestahl's Empire. Gestahl tries to talk Kefka out of whatever he's about to do, and then tries to kill him, but Kefka is already too powerful; he kills Gestahl instead. Then he moves the Statues out of their precise alignment, an action guaranteed to cause serious damage to the world. The group runs for their airship, making it out just in time. But then the magical imbalance begins to take its toll, and the face of the world is changed forever...

For the next year, people slowly begin recovering from the destruction, although nature does not. Then the group slowly reassembles itself and goes after Kefka, who, for all practical purposes, is now the source of magic. They finally defeat him... but with the fall of Kefka, magic ceases to exist.
