-The evil Paramekia Empire has an iron
grip on the world. A rebel army, led by the king of Phin, tries to organize a
coup against the Empire, but fails time and time again.
-The empire is able to overrun the kingdom of Kashuon because of the actions of Borgan, its general, who betrayed the kingdom. Gordon and Scott, the princes of Kashuon, travel to Altea help the king out in his ventures.
-In an attack to attempt to regain Phin Castle, both the king of Phin and Scott of Kashuon are fatally wounded. The king's daughter, Hilda, takes the king to Altea, the rebel base, and takes over in his stead. Scott, unable to escape, is hidden underground by a member of the Rebels.
-Four youths, Frioniel, Guy, Maria, and Lionheart, are also fighting against the Empire. They are wounded in battle. Lionheart is taken by the enemy, but the rebels rescue the other three. They are taken to Altea.
-Lionheart is brainwashed by the Paramekian Emperor and takes on the persona of a Dark Knight. He is put in charge of the mission to build a giant Warship for the Empire, which is based in the city of Bofsk.
-The three youths decide to search for Maria's brother Lionheart. Their first stop is Phin, where the passwords they learned from Hilda gain them access to Scott's deathbed. They take Scott's ring to Hilda, where they learn more of the rebels' plans. Without the legendary metal, Mithril, the rebels have no chance against the Empire. Hilda sends the three youths, along with her magician Minh (Minu), to Semite Cave to procure some. Minh has a canoe which allows them to travel east.
-They travel from the city of Palm by sea to Poft, and from there via an airship owned by a man named Cid, to reach Semite Cave. Villagers from the city of Salmando are forced to mine for Mithril here. Two of the miners are Paul, a thief, and Nellie, the daughter of Josef from Salmando. They are rescued by the three youths and Minh, who also find a cache of Mithril, which they return to Altea with.
-Hilda now decides to send the youths and Minh to Bofsk to stop the building of the Warship. When they arrive they overhear rumors that the Dark Knight has been called back to Paramekia, and Borgan has taken his place as overseer of the Warship project. However, Borgan is sloppier than the Dark Knight, and the youths manage to sneak in via the sewers. However, the Dark Knight is waiting for them, and informs them that the Warship is already complete; he and Borgan escape on it. They strafe several cities and kill many people. Gordon escapes to Kashuon to attempt to retrieve an item called the Sun Flame; most think he just ran away. Before leaving Bofsk, the three youths pick up a pass that the Dark Knight leaves behind.
-Cid in Poft tells them that the only way to destroy the Warship is by throwing Sun Flame into its engines. The Flame resides on the lowest floor of Kashuon. However, to be able to carry the flame they require the Ergil Torch, which itself resides on the highest floor of Kashuon. To be able to get even there, however, they also require the Goddess Bell to open the door. The Bell is hidden in the Snow Cave to the north.
-Josef of Salmando knows the way to the Snow Cave, but in order to cross the Snow Field they will require the Ice Sled, which is hidden back in Semite Cave. Josef and the three youths travel there and pick up the Ice Sled. They travel to the Snow Cave. Aided by friendly beavers (whom apparently only Guy can understand) they find the Goddess Bell. However, Borgan the traitor shows up. He is defeated by the party, but causes an avalanche which forces Josef to sacrifice himself to save the others.
-The three youths now travel to Kashuon, where they meet Gordon, who joins them. Together they collect both the Ergil Torch and the Sun Flame. Hilda and Cid arrive in Cid's airship to take you back to Altea, but they are intercepted by the Warship and both Hilda and Cid are taken prisoner.
-The pass left by the Dark Knight gains the three youths and Gordon access to the Warship. They sneak inside, rescue Hilda and Cid, and throw the Sun Flame into the Warship's engine, destroying it.
-Back in Altea, the wounded king rewards Gordon by giving him a post in Altea; he also sends the magician Minh to look for the legendary ultimate magic spell, Ultima. The king sends the three youths to Dist Castle, home of the Dragoons, in hope of gaining their support. The king then passes away.
-The three youths take a ship from Palm to Dist. However, it turns out to be a pirate ship, led by a woman named Layla. However, the youths defeat the pirates, and Layla joins their quest and lends them her ship.
-In Dist Castle, there are only two survivors, a woman and child. They tell the party that all the Dragoons have been killed, and there is only one dragon (Hiryuu) left. However, no non-Dragoon can understand the Hiryuu without a magical Pendant which is hidden in Dist Cave.
-They find the Pendant. The Hiryuu tells them that it is dying. It mentions that there is one Dragoon named Richard, who escaped the destruction of Dist when he left to look for Ultima as well. Finally, the Hiryuu asks the party to take its egg to the Spring of Life inside Dist Cave. They do so, and return to Altea.
-On their arrival they discover that Hilda has been captured, and a doppelganger (a Lamia) has been ruling in her place. They dispatch the monster and learn where Hilda is being held: at an Arena, where the Emperor plans on giving her away as a prize to whoever beats the monsters there. Gordon accompanies the youths there while Layla stays in Altea.
-The youths and Gordon beat the monster, but are betrayed by the Emperor and taken prisoner. However, they are rescued by Paul, the thief, as a reward for rescuing him from Semite Cave. They regain Hilda and return to Altea, where Gordon stays.
-With the help of Mithril and Layla's pirates, the rebels have organized themselves to be ready to attack the Emperor's stronghold in Phin Castle. Everyone has moved to a camp near the castle. They succeed in defeating Gotus, the guardsman, and Phin is retaken.
-Hilda tells them that since Minh has not returned from his quest for Ultima, they should go to Mysidia to search for him. To do so, though, they need the White Mask hidden in the Phin Castle Basement. With a hint from Paul, they find it and head for Mysidia.
-They learn that the Ultima magic is hidden in Mysidia Tower. To enter, they need the Crystal Rod hidden in the Mysidia Cave; to gain access to that, they need the Black Mask hidden in Black Mask Cave. They collect the mask and rod, and head to the tower, which lies inside a crescent-shaped coral reef.
-Before they can get there, they are swallowed by Leviathan, a sea monster who defends the Ultima spell. Layla disappears. They find an entire village of people swallowed by the monster as they searched for Ultima; included in these is the Dragoon Richard, who joins them. Eventually they find their ship and escape Leviathan's maw to enter Mysidia Tower. They find four crystal orbs and the Ultima magic inside the tower; Minh sacrifices himself to break the seal to the Ultima magic.
-When they come out they discover that the Paramekian Emperor has unleashed a whirlwind which destroyed Altea, Gatea, Palm, and Poft, and Phin is under attack. Powerful monsters have been unleashed on the world as well. Layla is in Phin, having gotten out of Leviathan by herself. They discover that the egg from Dist Cave has hatched into a Hiryuu, which flies them to the Whirlwind, where the Emperor hides.
-They manage to reach the Emperor and defeat him, but he has signed a pact with the Devil after which he is allowed to return from death. Before he does so, though, the Dark Knight takes over the Emperor's throne and rules from Paramekia Castle.
-Cid, who was fatally wounded by the Whirlwind, leaves his Airship to the three youths and Richard. They use it to reach the mountain-bound Paramekia Castle. When they reach the throne room, the newly-resurrected Emperor tries to kill the three youths, Richard, and the Dark Knight, who reveals his real self as Lionheart. Richard distracts the emperor long enough for the other four to escape, but is killed for his efforts.
-The emperor changes Paramekia Castle to Pandemonium, which is connected to Hell. The four youths manage to reach the new castle by going through the magical Jade Portal. They confront the Emperor and defeat him for once and for all. Side Quests: -South of Kashuon is a secret forest where a Chocobo lives. If you catch it you can ride it without being accosted by enemies. -If you visit Richard's house after he dies, his wife gives you the Excalibur sword.
