Star Ocean : Integrity and Faithlessness
The game occurs in Space Date 537, set between Star Ocean: The Second Story and Star Ocean: Till the End of Time, centuries after humanity has spread out from Earth. After multitudes of trials and the spread of the Galactic Federation, humanity is on the verge of peace. However, on the planet Faykreed, embers of conflict have begun to stir.
Most of Integrity and Faithlessness takes place on Faykreed, where the player explores its three kingdoms, Resulia, Trei'kur, and Langdauq. The Kingdom of Resulia is at war with Trei'kur, but has a peace and cooperation agreement with Langdauq. This war sets the stage for the conflict of the game.
Although Trei'kur would normally be a match for Resulia, their soldiers have begun to wield mysterious weapons that cause a flash of light and then death to whomever they target. This gives Trei'kur an edge in the war and is forcing the Resulians into retreat, causing them to recruit aid from the signeturges of Langdauq, the most powerful ones in the world.
