Final Fantasy Tactics

The story takes place in the kingdom of Ivalice, inspired by the Middle Ages. The kingdom is located in a peninsula surrounded by sea on the north, west and south, with a headland south of the landmass. It is heavily populated by human beings, although intelligent monsters can be found living in less populated areas. Magic is predominant in the land, although ruins and artifacts indicated that the past populace had relied on machinery, such as airships and robots. Ivalice's neighbors are the kingdom of Ordalia in the east and Romanda, a military nation to the north. While the three nations share common royal bloodlines, major wars have taken place between them. An influential religious institution known as the Glabados Church heads the dominant faith, centering around a religious figure known as Saint Ajora.

After Ivalice ended its war with the two nations in what is known as the Fifty Years War, and facing economic problems and political strife, the king of Ivalice has recently died and his heir is an infant, so a regent is needed to rule in place of the prince. The kingdom is split between two candidates named Prince Goltana, represented by the Black Lion, and Prince Larg, symbolized by the White Lion. The conflict leads to what is known in the game as the Lion War. Behind this backdrop is a revelation by the game's historian Alazlam J. Durai, who seeks to reveal the story of an unknown character whose role in the Lion War was major but was covered up by the kingdom's church.

The story is presented as a historical account by Alazlam J. Durai based on recently-discovered documents dubbed the "Durai Report", written by his ancestor Olan Durai. Ivalice is recovering from the Fifty Year War against Ordalia. After the death of its ruler, Princess Ovelia and Prince Orinas are both candidates for the throne. The former is supported by Prince Goltana of the Black Lion, and the latter by Queen Ruvelia and her brother, Prince Larg of the White Lion. The two groups engage in battles in the Lion War. Nobles and commoners regard each other negatively and many commoners joined the Corpse Brigade to fight against the nobles' soldiers.

Ramza, part of the noble Beoulve family of knights, and Delita, his childhood friend who was an ordinary commoner, witness the murder of Delita's sister during an uprising. This causes Delita and Ramza to abandon their ties to the nobility. Ramza joins a mercenary group, led by Gafgarion, who protects Princess Ovelia from being hunted by both sides of the Lion War. Delita joins Goltana's forces. They are reunited when Gafgarion attempts to take Ovelia to Prince Larg. Agrias suggests visiting Cardinal Delacroix of the Glabados Church to protect Ovelia. Along the way, Ramza meets Mustadio, a machinist in possession of a holy relic called the Zodiac Stone. Hunted by a trading company for the power it contains, Mustadio also seeks Delacroix's intervention.
