The war's after effects are seen throughout the world, most notably the orphans whose parents and families died during it. A large portion of Laguna Loire's story also occurs during the war.
Vinzer Deling became the president of Galbadia sometime beyond nineteen years ago, whereupon he began to unite the independent nations within the Galbadian continent by amassing a military dictatorship. It is unknown how Sorceress Adel came to her position of power within Esthar, whether it was a coup or election, but she also wanted to unite the world under her power.
The two year-long war spread across the globe with reported events occurring in the Centran, Galbadian and Estharian continents.
The war was initiated by the tyrannical Sorceress Adel, who ruled over the technological nation of Esthar and terrorized it with magic. She attempted to take over Galbadia using a combination of her magic and Esthar's technology, but Galbadia resisted. During the fighting many children ended up orphaned, among them: Squall Leonhart, Zell Dincht, Irvine Kinneas, Selphie Tilmitt, Quistis Trepe, and Seifer Almasy.
Esthar discovered the crystal pillar, a device that could react with the moon to incite a phenomenon called the Lunar Cry. The last Lunar Cry destroyed the Centra civilization, and Adel planned to use it as a weapon against Galbadia by building an enclosure dubbed the Lunatic Pandora around the pillar to amplify the Lunar Cry's power.
Galbadian troops led by Laguna Loire investigated the facility, but were forced to jump from a cliff after being cornered by Estharian troops, leaving them momentarily crippled and the mystery unsolved. The second breakthrough came when Dr. Odine stumbled across the secret of junctioning Guardian Forces to human minds, allowing regular humans access to an incomplete kind of magic known as Para-Magic.
As Adel had no one to pass her empire on to, she began desiring a successor to her sorceress power, and began to search for an appropriate girl to carry on her legacy. The girl she chose was Ellone, a mysterious girl from Winhill who had the ability to send another person's consciousness back in time. Esthar troops raided Winhill and killed Ellone's parents, but she is saved by her next-door neighbor, Raine.
Following the raid, Galbadian troops were stationed in Winhill to fend off future attacks. Esthar attacked again, and Ellone was kidnapped and taken to Esthar where Dr. Odine imprinted her brainwaves into a computer to create the Junction Machine Ellone to simulate her time-traveling powers.
Laguna Loire rescued Ellone and joined the rebellion against Adel that hatched a plan to usurp her. Although she was too powerful for any non-sorceress to defeat, Laguna tricked Adel into a sealing container using Ellone's facsimile, then launched the container into space. The container's anti-transmission waves caused the worldwide radio interference, which would render wireless communication useless for the next seventeen years.
With Adel disposed, Laguna became the president of Esthar and ordered the crystal pillar to be sunk into the ocean. Esthar sealed itself away from the rest of the world, and became known as the Silent Esthar.
The war's aftermath can still be felt seventeen years later with the abundance of war orphans (most of whom are now in their mid to late teens) and the static over radio-wave transmissions. Relations between Esthar and Galbadia were never patched up, as the former had cut itself off from the rest of the world. With Esthar remaining in isolation, Galbadia became the world's de facto superpower.
