"A fortress built on an oasis located between the old kingdoms of Dalmasca and Nabradia. Defended by high ridges and barren sands, long it stood firm against generations of aggressors. Nalbina Fortress and the merchant town that sprung up in its shadow made the area a focal point for local commerce. The treaty to end hostilities in the war with Archadia was signed at Nalbina, yet immediately after the signing, the Dalmascan king was slain, and as a result, the Kingdom of Dalmasca came under complete Archadian Imperial rule. In the two years since the war and occupation by Archadian forces, the fortress has become a key strategic stronghold against the distant, yet ever-threatening, Rozarrian Empire. Works continue to this day to repair the damage which the fortress suffered during the war. Recently, markets where antiques and rarities can readily be had have sprung up in the outer wards of the fortress, taking advantage of the steady flow of traffic which passes through this midpoint between Rabanastre and Nabudis. It is this pivotal location that gives the fortress its unique character. Many are the travelers who visit Nalbina Fortress to witness this ever-booming oasis that refuses to silt over in neglect, or crumble before the blistering winds of war."
During the game's prologue, that also works as a tutorial, the player controls Reks on the Order of the Knights of Dalmasca's quest to save King Raminas from a plot to assassinate him. The player may find two treasures in the Lower Apartments area, and they are both Potions. Later on the player may visit the town that has sprung outside the fortress, but it has no treasures to be found.
It was here, during the Battle of Nalbina Fortress, that the Knights of Dalmasca were decimated, and Prince Rasler succumbed to the arrow of an imperial soldier. A short while later, King Raminas was assassinated in the royal apartments, marking the end of autonomous rule for Dalmasca. A young soldier named Reks also died as a result of being wounded in the assassination, and Dalmasca's Captain Basch fon Ronsenburg was charged with the crimes.
After the imperials took control of Nalbina Fortress, it was utilized primarily as a prison. However, the city itself was rebuilt, and now contains a thriving market and airship dock.
