Zavala: Oryx could be anywhere on the Dreadnaught. With time, we could find him, but we don't have time. The Cabal have been there long enough to have real field intelligence. The path to Oryx lies on their ship.
Ghost: The Cabal are still holding out. Multiple survivors.
Zavala: Survival's a temporary condition. Cut through them, and get inside their ship.
Ghost: Who fights this hard to protect a crashed ship?
Zavala: That's not a crash site, it's a beachhead. Only way those doors will open is to send reinforcements. Draw them out.
The Cabal send for reinforcements
Ghost: I think you got their attention.
Zavala: When those doors open, fight through it.
Ghost: Zavala, we're in. What's next?
Zavala: Cabal protocol is to detonate any ship that crashes. If they haven't after all this time it must be a base of operations. They're looking for something on the Dreadnaught. See what they know about Oryx.
Ghost: Oh nice! There's a terminal nearby. It should have the info we're looking for.
Ghost: The Cabal have located Oryx. He's protected in the center of the Dreadnaught, reachable only through something they call 'a rupture'...
Zavala: Must be some kind of portal. Have the Cabal found one?
Ghost: They've got a team heading for it right now.
Zavala: Then I suggest you get there first.
Mausoleum, Dreadnaught, Saturn's rings
The Cabal, lead by Valus Ta'aun, battle with Taken
Ghost: We found the Cabal team headed for the rupture. They're outnumbered by Taken.
Zavala: Forget what they say about "the enemy of my enemy". Something stands between you and the rupture, put it down.
Ghost: Those Cabal won't last much longer.
Ghost: Oryx just recruited a Centurion.
Zavala: Let him take all he wants. He won't be around long enough for it to matter.
Ghost: That must be the rupture.
Zavala: Eris, what's their next move?
Eris Morn: Toland spoke of statues the Hive use to navigate ruptures.
Ghost: We'll look for them.
Ghost: I'll see if it's still active.
Ghost scans the first statue
Ghost: It's linked to the rupture but I can't understand how the Hive control it. Let's try another statue.
Ghost scans a second statue
Eris Morn: Yes, the statues control where the rupture leads. They could deliver us to Oryx!
Ghost scans a third statue
Ghost: It's dead, but something's happening at the rupture.
The rupture opens
Zavala: The rupture's opening.
Thrall begin coming through
Eris Morn: The Thrall will smother your Light! Do not underestimate them as Tarlowe did!
Zavala: Forget about the Thrall, get through that rupture.
The rupture pushes the Guardian back, preventing access
Ghost: I don't think we're going that way.
Eris Morn: Then it's true, only the Ascendant can will a rupture to open.
Ghost: There's something Ascendant passing through right now...
An Echo of Oryx emerges from the rupture
The Guardian defeats the Echo of Oryx
Ghost: The rupture is closed.
Eris Morn: It will only open for Ascendant Hive.
Ghost: Then how do we reach Oryx?
Eris Morn: Become your enemy. Become Ascendant.
Zavala: We'll sort this out, Guardian. Head back to the Tower when you can.
