Plot Elements

 * Rex, an orphaned salvager who collects treasure from below the Cloud Sea for money, is hired by Argentum Trade Guild Chairman Bana to aid the Drivers Jin, Malos, and Nia, part of a group named Torna, in the salvage of an ancient ship. In the ship, they find Pyra, a legendary Blade known as the Aegis.
 * When Rex reaches out to touch Pyra's sword, Jin fatally stabs him. Rex awakens on a field with Pyra, who reveals they are in a memory of her old home Elysium. She asks him to bring her to Elysium and in exchange gives him half of her Core Crystal to revive him.
 * With help from his Titan companion Azurda (whom Rex calls "Gramps") and Nia, who has defected from Torna, Rex escapes to the Titan Gormott, but Azurda is wounded and reverts to his larval stage. Soon after, they arrive in Gormott's capital Torigoth and are joined by the Nopon Driver Tora and his artificial Blade Poppi.
 * The group try to get to Elysium, but are stopped by Ophion and swallowed by the Titan Uraya.
 * After the group battles the mercenary Driver Vandham while escaping Uraya's stomach, he joins the party and Rex begins to look to him as a mentor.
 * The group later learns that Jin and Malos are the leaders of Torna, a terrorist group named after a Titan destroyed in the Aegis War 494 years ago. Led by Jin, an embittered veteran Blade of the Aegis War, and Malos, later revealed as the other Aegis, they seek to destroy humanity by unleashing Aion on Elysium.
 * During a battle with Malos and fellow Torna member Akhos, Vandham is killed and Pyra unveils her true form Mythra. They have shared memory and consider themselves sisters, switching back and forth as needed.
 * The group's search for a way past Ophion leads them to join forces with Mòrag, special inquisitor of Mor Ardain and elder sister of the Ardainian Emperor, Niall; and Zeke, prince of Tantal.
 * In Tantal, the group battles Jin, who forces Pyra to surrender.
 * While Azurda leads the group to the third Aegis sword to save Pyra, Malos siphons Pyra's power to regain his full strength.
 * After the group finds the third sword, phantoms of Pyra's former Driver nearly kill Rex, but he is deemed worthy of the third sword.
 * The group confronts Jin and Malos at the Cliffs of Morytha, during which Rex unlocks Pyra and Mythra's true form Pneuma.
 * Rex, now matched with Jin's power, forces Malos to summon Ophion, who knocks the group into Morytha, the devastated land beneath Cloud Sea.
 * In Morytha, the group is forced to work with a weakened Jin.
 * Malos' driver, Amalthus attacks by controlling various Titans. The group severs his connection to the Titans, only for him to kill all Torna members except Malos and Jin, with Jin defeating Amalthus as he dies.
 * The group arrives in Elysium and meet the Architect, a scientist named Klaus who explains that he had discovered a device that sends objects into different dimensions, the use of which split his body in two and destroyed the old world.
 * Sensing that his other half is about to die, which will result in his own death, Klaus sends the group to stop Malos, who was corrupted by Amalthus's malice and has obtained Aion.
 * After Malos's defeat and death, Klaus dies, but not before granting Rex and the party a "final gift".
 * Klaus's death causes Elysium to begin crumbling.
 * Pneuma helps the group escape, but sacrifices herself to detonate the World Tree, preventing its debris from destroying Alrest.
 * The group barely survives when Azurda, thanks to Pneuma, returns to his adult form and flies everyone down to Alrest.
 * On returning to Alrest, the Cloud Sea fades to reveal a rejuvenated world, the Titans merging to form a new landmass.
 * Afterwards, Pyra and Mythra are revived in separate bodies and reunite with Rex.
 * Mid-Credits Scene: Unfortunately, the reunion is short-lived as Rex suddenly disintegrates into golden dust particles right in front of Pyra and Mythra's horrified eyes.
