The Plot

One year after the end of the SIVA Crisis, Cabal forces of the Red Legion sever external communications throughout the Solar System and launch a full-scale aerial assault on the Last City, destroying the upper main portion of the Tower. The Guardian and Ghost respond and assist the Vanguard (Commander Zavala, Ikora Rey, Cayde-6, Lord Shaxx, etc.) in the evacuation of civilians, but while assaulting the Cabal command ship of Dominus Ghaul, the military emperor of the Cabal, he attaches a massive mining device to the Traveler and drains it of the Light, a special form of power used by the Guardians. The Guardian loses their powers and is nearly killed by Ghaul. Waking two days after the attack, the Guardian locates their Ghost and the two escape the Last City and find a safe haven known as The Farm in the European Dead Zone (EDZ) with the assistance of Suraya Hawthorne, a non-Guardian human who lives on the outskirts of the Last City and helps refugees.

The Guardian follows a vision they experienced and encounter a shard of the Traveler in a hidden forest within the EDZ. Ghost interfaces with the shard and its Light is restored. In doing so, Ghost is successful in restoring the Guardian's Light as well. After completing a series of missions for Hawthorne and Devrim Kay, an EDZ scout, to restore long range communications, Hawthorne intercepts a distress call from Commander Zavala, urging any surviving guardians to make their way to Saturn's moon Titan to assist in mounting a counter-offensive. It is shown that Ghaul has captured the Speaker, and wishes to carry favor with the Traveler, having taken an interest in harnessing and learning the power of the Light.

The Guardian travels to the former human colony on Titan, only to learn it has been overrun by the Hive. Tasked to complete a series of missions for Deputy-Commander Sloane, power is successfully restored to the facility and Zavala summons the Guardian to retrieve Cabal intelligence for analysis. After doing so, it is revealed that the Red Legion was dispatched to the Milky Way in response to the distress call sent by the Skyburners Regiment during the Taken War two years prior. It is also learned that Ghaul is undefeated and possesses a superweapon known as the Almighty, an orbital space station with a drilling platform capable of destroying stars. Anyone who has resisted Cabal rule in their system has subsequently had their star drained and their star system destroyed in the process. Ghaul implores the Speaker, under duress from torture, to tell him how to commune with the Traveler; the Speaker responds that Ghaul is not worthy of the Light and that the Traveler will never deem him worthy. Regardless, Ghaul refuses to kill the Speaker, stating his intention to torture him until he reveals how to commune with the Traveler. Zavala tasks the Guardian to find Ikora Rey and Cayde-6 to assist in facilitating a counterattack to retake the Last City.

The Guardian locates Cayde on the centaur planet Nessus, who was looking for Vex tech to use against the Red Legion, and Ikora on Jupiter's moon Io, who was looking for answers about the Traveler as Io was the last place the Traveler visited before the Collapse. After eliminating Vex and Taken threats at each location, the team reunites at The Farm and conclude that the only way to retake the Last City and save the Traveler will be to shut down the Almighty first, to eliminate the possibility of the Red Legion destroying the Solar System in the event of their failure. The Guardian proceeds to kill Thumos the Unbroken, the Cabal officer in possession of access codes to a ship that will allow them to access the Almighty. The Guardian is successful in hijacking the ship and subsequently boards the Almighty, eventually destroying the weapon, which also blows up the base in the process. During this time, the Consul, Ghaul's mentor, urges Ghaul to take the Light, but Ghaul is reluctant until the Consul kills the Speaker. Ghaul then proclaims that he will take the Light and strangles the Consul in a fit of rage.

The Guardian returns to Earth to assist in the counterattack and

, after a short rendezvous with Cayde, Ikora, Zavala, and Hawthorne, infiltrates Ghaul's command ship alone to face him and save the Traveler. Ghaul forcibly takes the Light, corrupting it, and uses its power against the Guardian, but the Guardian is successful in killing Ghaul, who uses Radiance in order to resurrect as a massive ethereal figure who then speaks to the Traveler directly. In doing so, the Traveler wakes from its sleep, destroying the device that was harvesting its power before vaporizing Ghaul himself, sending a massive shockwave across the planet, restoring the Light and decimating the Red Legion's forces. The game ends with a posthumous voiceover from the Speaker, reminding those who would oppose the Light may try, but that it can never be stopped.

After this, the Guardian and Ghost convene with Zavala, Ikora, Cayde, and Hawthorne at a lower, undamaged portion of the Tower (and once again a social space), with the Vanguard returning to their old duties and Hawthorne assuming a new post in the Tower. In a post-credits scene, the shockwave sent by the Traveler is revealed to have encapsulated the entire system, ushering in a new Golden Age. The wave of Light extends beyond the Solar System and spreads beyond the entire Milky Way, before panning across a fleet of dark, unknown ships sitting some distance away in extragalactic space.

Following Ghaul's defeat, a massive world-eating ship called the Leviathan appears outside of Nessus's orbit ("Leviathan" raid). A fireteam of Guardians board the ship and are greeted by the Cabal emperor-in-exile, Calus. He invites them to complete a series of challenges before reaching his throne. The Guardians complete his challenges at the Royal Pools, the Pleasure Gardens, and the Gauntlet (the order of which changes weekly), before facing Emperor Calus. As he takes damage, the Guardians discover that Calus is a mechanical doppelganger. After overcoming his strange powers and the automaton, the real Calus speaks through the machine, claiming that what the Guardians know is a lie and that there is a truth beyond what the Speaker had told them.
