Jack and his allies embark on a journey through time and space, guided by an enigmatic moogle spirit. They travel to Central, a city in another dimension, where they observe a myriad of worlds and dimensions. However, it takes only the mad delusions of one Lufenian to bring it all to ruin. Jack strides deep into the heart of this ghostly city to break the fetters of this karmic juggernaut once and for all. Along the way, they encounter the Emperor, a powerful entity who is also seeking the power of the crystals and chaos. They also come across Omega, an interdimensional weapon with the power to destroy gods. Jack and his allies must use their new jobs, such as Musketeer, Hunter, and Gambler, as well as their new blacksmith features, such as Imitation Materials and Fabrication, to save Lufenia from interdimensional interference and fix a broken future.
