On that day, the World was changed forever...
The end of the world is the destruction of the World of Balance in Final Fantasy VI. The event is alluded by several characters, both playable and non-playable, being referred to as "the very day the world collapsed", the "cataclysm" and as collapse of the world (世界崩, sekai kuzure?) in the Japanese version. Witnessing the end of the world in the mobile/Steam version earns the Washed Up on Solitary Island achievement.
After the attack on Thamasa, Emperor Gestahl and Kefka Palazzo raise the Floating Continent, uncovering the Warring Triad, a trio of petrified deities. When the Returners attack the Floating Continent, Kefka attempts to revive the Triad, but Gestahl, knowing the gods' alignment affects the shape of the planet, urges him to stop. Gestahl uses a variety of powerful magic to attack him, but Kefka uses the power of the Triad to defeat him before pitching his body off the Floating Continent. Kefka begins repositioning the Triad, destabilizing their magical field.
Through the intervention of Shadow, the Returners escape to Setzer Gabbiani's airship and flee the Floating Continent. If the party waits for him, within the last five seconds of the Floating Continent's destruction Shadow will arrive, stating, "I'll be blown to bits before I can even collect my pay..." and join the rest of the party on the airship. If the party doesn't wait for him, Shadow will die.
The Triad being out of alignment results in imbalance of power, shattering the world's main continents into a series of islands, releasing many sealed monsters like Deathgaze, Humbaba and the eight legendary dragons, killing countless people and animals and destroying Setzer's airship, from which the party bails just in time, though they wind up separated in the chaos. The new world comes to be called the World of Ruin where many plants refuse to grow, monsters infused with magic roam the wasteland, and Kefka is worshiped as a god. Now the sole ruler of the world, Kefka rains down doom and destruction with the Light of Judgment from his tower.
After Kefka is killed by the regrouped Returners, the people begin to rebuild and undo the damage the world has sustained.
The track that plays during the end of the world scene is "Metamorphosis".
Eschatology is a part of theology, physics, and futurology concerned with what are believed to be the final events of history, or the ultimate destiny of humanity. This concept is commonly referred to as the "end of the world" or "end time".
- The end of the world is briefly foreshadowed in the game's title screen with the thunderstorm, as well as the text for the game being engulfed in flames and cutting to what is implied to be destroyed towns.
