The Black Garden
The Guardian makes their way to the Valley of the Kings, returning to the massive Gate they previously discovered.
Blinding light surrounds the Guardian until they are teleported to an unknown location. The gate closes behind them.
The area is occupied by dozens of Vex, seemingly frozen and completely oblivious to the Guardian's presence. Moss and plant life hang from their limbs and heads, a sign that they have been inactive for years.
As the Guardian continues walking, some of them start to come to life and attack. The Guardian kills them and makes their way through the Black Garden. They eventually come across a cliff overlooking the Garden itself.
The Guardian continues slaughtering Vex, until they come across a large force field blocking their exit. In front of the barrier is a Major Hydra, the Divisive Mind.
The Guardian kills the squadron of Vex, including the Divisive Mind.
The Guardian makes their way further below, coming to a stop in a large square pavilion. A locked circular door sits on the far side, and dozens of Vex teleport in through spawn clouds.
The Guardian fights their way through multitudes of Vex and reaches a cluster. They let Ghost analyze it.
On a large plateau in the center of the pavilion, a massive obelisk of light begins to form, taking a rectangular shape.
The Guardian makes their way to the other cluster and sends the Ghost to scan it.
The 'box' of light on the plateau disappears and a Spire takes its place. The Guardian heads to the circular door, where a Conflux appears. The Ghost activates it.
The Conflux disappears, and a small grid of light in the shape of a door appears in front of the Guardian. It eventually solidifies in place, then suddenly lifts high in the air. Behind the Guardian, the Spire fires a beam of light, and the 'door' breaks into several smaller pieces. The light reflects off of each piece, pointing towards the circular locked door. The door succumbs, each segment pushing back in eights, before the bottom half splits open slowly.
The Heart's darkness turns the bright teal environment into an abysmal dark brown. As the Guardian walks through the large door, the camera cuts to black.
The Guardian walks slowly forward, as the camera pans upward to show the Heart of the Black Garden, pulsing with arcane energies. Three gargantuan stone statues of Gate Lords surround the heart, as if defending it. On the ground below, several Vex Goblins and Hobgoblins kneel in front of the heart in their own form of worship. Upon sensing the Guardian's presence, they slowly start to activate, and turn to the source of the intrusion, red lights glowing as if they are angry. They start to rise and advance on the Guardian.
The camera focuses on the Heart, as one of its electronic pulses slowly reach out towards the center statue. Fades to black.
The Guardian leaps into the center of the coliseum, killing the Disciples of the Sol Divisive. Once the Vex are eliminated, the Heart sends a pulse of energy to the statue on the left. It cracks, ruptures and breaks, revealing light underneath. The pedestal on which the statue stands slowly starts to sink, rotating as it does so.
The rubble eventually explodes, revealing a Sol Progeny, the Eschaton Mind. It removes an enormous Torch Hammer from its back and proceeds to fire on the Guardian. More Vex units appear to support it. They are all eventually destroyed.
The Heart sends another pulse, now to the statue on the right. It starts to come to life as the Eschaton Mind before it. The Imminent Mind, along with its subordinates, is eliminated. Finally, the Heart sends a pulse to the final statue in the center. The final Sol Progeny, the Primeval Mind, battles the Guardian, with Minotaurs and Harpies providing assistance. Eventually however, the Primeval Mind is destroyed. The coliseum starts to violently shake as the Heart starts to expand and falter, surging with energy. An explosion of white light washes over the Black Garden, temporarily blinding the Guardian. When their vision clears, nothing is left of the heart but floating embers, still lit. The environment's color has returned, and a peaceful quiet surrounds the Garden.
The camera fades in on a shot of the Traveler, panning down to the Tower in The Last City. The plaza is nearly overflowing with Guardians, watching with reverence as the Speaker addresses them from the front of the plaza.
The camera cuts to the hangar of the Tower, with The Guardian's ship is docked. The Exo Stranger stands at the end of the hangar, and the Guardian is seen walking towards her, Ghost in tow. The Speaker can still be heard in the distance.
The Guardian reaches the Stranger at the edge of the dock.
The camera cuts to a shot of them looking out towards the Traveler, and beyond. The Stranger picks up her weapon and hands it to the Guardian.
The Guardian picks it up and lets it settle into their grip as they look it over.
She steps forward, off the platform, and dissipates into blue-white energy. The Guardian turns and walks toward their ship. It powers up and takes off, departing from the Tower, and Earth's orbit, as they start their new adventure. Fades to black.
