The Iron Tomb
The Guardian mounts their Sparrow and heads toward Giant's Husk.
The Guardian arrives at the beached tanker, fighting off Splicers as they ascend the stairs towards the interior.
The Guardian heads inside and finds the center of the ship, swarming with Splicers. Threads of SIVA have wrapped itself around most of the terminals and computers inside.
Two cores sit on opposite sides of a small staircase, each guarded by Dregs and Servitors. The Guardian removes one core, walks around to the other side, and places it in the incorrect reactor.
The Guardian repeats the process with the second core, and small explosions start to rock the interior. SIVA nodes start to react visibly, sparks flying and electrical currents surging through the cord-like substance.
One of the explosions opens a hole in another side of the ship, offering a shortcut back outside. Back on their Sparrow, the Guardian races towards the Archon's Keep.
As the Guardian makes their way through the Doomed Sea, more nodes are seen damaged and offline; some even explode in close proximity to the Guardian as they drive past. Upon reaching the Archon's Keep, a massive explosion tears through the observatory in the far distance.
As the observatory smolders in flames, the Guardian continues. As they approach the Forge, the entrance explodes right in front of the Guardian. Several Fallen are seen, either dead or blinded by the blast, staggering outside. Either the Guardian kills them or uses the opportunity to proceed inside.
Encountering a Captain and some Dregs, the Guardian kills them and makes their way into The Warrens.
The Guardian finds a small, narrow vent further within The Warrens, and Ghost is forced to activate his flashlight. A breadcrumb trail of SIVA litters the vent, and the Guardian finds an opening to drop out of. Now underground, the Guardian fights off large waves of devout Splicers guarding the area.
The Guardian comes across a locked door with a terminal sitting near an observation deck. The Ghost is sent to unlock the door, while the Guardian notices a high-ranking Captain with a Scorch Cannon on the bottom floor. After the door opens, the Guardian eliminates the Captain, along with multiple Dregs, Vandals and Tracer Shanks.
The Guardian learns the Captain was guarding a hole in the floor. Looking below, they find an immeasurably long fall, leading down to what appear to be inner caves. More of Rasputin's structures are found built into the natural formations. The Guardian jumps down.
The Guardian uses their movement ability to prevent what would've been a certain death from the fall. A few Splicers exit a room to the Guardian's right. One of them shoots a flare. The Guardian opens fire.
They continue forward, wiping out more Fallen squads. Once they reach the blast door bearing Rasputin's symbol, the door opens for them, revealing the hallway where the Iron Lords made their last stand. The entire area is shrouded in dark red light; there are strong threads of SIVA covering every square foot of the chamber, a haunting sight.
As they carefully journey further in, the Guardian sees the chamber, completely covered—even held aloft—by branches of SIVA. The chamber itself has been separated from the metal hallway, and now sits in an ocean of pulsing blood red; even the bridge across is composed entirely of the element. The Guardian walks inside and finds, among the solidified masses of SIVA, three hanging objects near the center, obscured by more and more red tendrils.
Upon closer inspection, the Guardian and Ghost find a horrifying sight: the objects hanging from the ceiling are dead bodies—the bodies of the Iron Lords. Gheleon, Felwinter and even Jolder's limp corpses line the chamber in a truly sickening display. At the front, an Iron Battle Axe hangs from Felwinter's hand.
The Guardian returns to the task at hand, and finds a small terminal. They send their Ghost to examine it.
A few lights activate as the Ghost continues his work, further illuminating the perversely deformed battlefield. Suddenly, Felwinter's body starts to glow and sway, a swarm of SIVA covering it.
Without warning, the body of Felwinter is yanked straight upwards, into the red abyss. The Iron Axe falls from his hands and lands in front of the Guardian.
Cautiously, the Guardian walks towards the Axe and picks it up. The very instant they do an enormous, SIVA covered being lands right upon the Guardian, sending them flying backwards. The monster, Remnant of Felwinter, towers massively over them and wields a heavy machine gun and what appears to be a prosthetic drill.
As the Guardian uses the Axe against the mutated creature, the symbol of the Iron Lords can be seen on all of Felwinter's armor; the SIVA has taken over it and uses the armor against the Guardian to further empower themselves. The Guardian attacks the Remnant with the Battle Axe vigorously. Should the Axe be fully drained of its power, several torches can be found in the area to Rekindle its flame. The Remnant is finally defeated, and dies in a brilliant flash of sizzling white light. The Guardian's relief quickly fades however—not only do Fallen Splicers appear and open fire on the Guardian, but both Gheleon and Jolder's bodies are absorbed into the chamber and are both made into Remnants at once. Fighting with all their might, and Rekindling their Axe where necessary, the Guardian eventually destroys the reinforcements, and defeat the Remnants of Jolder and Gheleon. The bodies of the Iron Lords are finally at rest.
The Guardian sends Ghost to resume the self-destruct sequence. The symbol for SIVA flashes on the screen, and large explosions shake the chamber. Like a blood-red fountain, dozens of tendrils of SIVA freely spray out from the computer terminal, and the rest of the infection hisses and sizzles, visibly in pain.
As more and more explosions destroy the area, the Guardian runs for their life back the way they came. A few more religiously devout Shanks and Dregs stay to slow the Guardian down, but they ignore them and escape to the exterior outside the hallway. The metal doors slam shut, and the final detonation, though muffled, quakes the entire underground facility. The threat of SIVA is finally over.
The view slowly fades in as the image slowly pans down the large tree inside the Iron Lords' Shrine. Lord Saladin stands at the base, in between the statues of Jolder and Silimar. The Guardian walks up to him, holding an object in their hands. Ghost follows along with them.
The Guardian lifts their hands, revealing Jolder's helmet, worn down with age. Saladin walks toward the Guardian and gently grasps the helmet. A light smile appears on his face.
He then turns towards the statues, revealing a small ceremonial stand bearing the Iron Banner insignia.
Saladin turns back to the Guardian and nods in appreciation.
The Iron Lord places Jolder's helmet on the stand, and above it, gently lifts a large broadsword. Holding the sword in both hands, he turns to face the Guardian.
The Guardian walks the last remaining steps to Lord Saladin. The Ghost looks closely at the sword.
Saladin holds the sword, The Young Wolf's Howl, up to the Guardian.
The Guardian retrieves the sword from Lord Saladin's hands, examines it, then turns toward the center of the Shrine, holding it in their hands, and gently touching the sharp tip of the blade to the ground. The camera cuts to a wide view of the Iron Lord Shrine, the statues honoring the Iron Lords of the past, and the reverent stance of the Iron Lord of the future.
Cut to black.
